Material Ratings and Definitions
INTRODUCTION
This Chemical Resistance Guide has been compiled to assist the
piping system designer in selecting chemical-resistant materials.
The information given is intended as a guide only. Many conditions can affect the material choices. Careful consideration must
be given to temperature, pressure and chemical concentrations
before a final material can be selected.
The physical characteristics of thermoplastics and elastomers
are more sensitive to temperature than metals. For this reason, a
rating chart has been developed for each.
MATERIAL RATINGS
FOR THERMOPLASTICS & ELASTOMERS
Temp. in °F
= “A” rating, maximum temperature
which is recommended, resistant
under normal conditions
B to Temp. in °F = Conditional resistance, consult factory
C
= Not recommended
Blank
= No data available
MATERIAL RATINGS FOR METALS
A
= Recommended, resistant under normal
conditions
B
= Conditional, consult factory
C
= Not recommended
Blank
= No data available
Temperature maximums for thermoplastics, elastomers and
metals should always fall within published temp/pressure ratings
for individual valves. THERMOPLASTICS ARE NOT RECOMMENDED FOR COMPRESSED AIR OR GAS SERVICE.*
This guide considers the resistance of the total valve assembly
as well as the resistance of individual trim and fitting materials.
The rating assigned to the valve body plus trim combinations
is always that of the least resistant part. In the cases where the
valve body is the least resistant, there may be conditions under
which the rate of corrosion is slow enough and the mass of the
body large enough to be usable for a period of time. Such use
should always be determined by test before installation of the
component in a piping system.
In the selection of a butterfly valve for use with a particular
chemical, the liner, disc, and stem must be resistant. All three
materials should carry a rating of “A.” The body of a properly
functioning butterfly valve is isolated from the chemicals being
handled and need not carry the same rating.
mercial sanitary systems. The residential DWV system can be
exposed in service to a wide temperature span. ABS-DWV has
proven satisfactory for use from -40°F to 180°F. These temperature variations can occur due to ambient temperature or the
discharge of hot liquids into the system. ABS-DWV is very resistant to a wide variety of materials ranging from sewage to commercial household chemical formulations. ABS-DWV is joined by
solvent cementing or threading and can easily be connected to
steel, copper, or cast iron through the use of transition fittings.
CPVC — Chlorinated Polyvinyl Chloride Class 23447 conforming to ASTM D1784, has physical properties at 73°F similar to
those of PVC, and its chemical resistance is similar to or generally better than that of PVC. CPVC, with a design stress of 2000
psi and maximum service temperature of 210°F, has proven to
be an excellent material for hot corrosive liquids, hot or cold water distribution, and similar applications above the temperature
range of PVC. CPVC is joined by solvent cementing, threading
or flanging.
PP (Polypropylene) — Polypropylene is a polyolefin, which is
lightweight and generally high in chemical resistance. Although
polypropylene is slightly lower in physical properties compared
to PVC, it is chemically resistant to organic solvents as well as
acids and alkalies. Generally, polypropylene should not be
used in contact with strong oxidizing acids, chlorinated hydrocarbons, and aromatics. With a design stress of 1000 psi
at 73° F, polypropylene has gained wide acceptance where its
resistance to sulfur-bearing compounds is particularly useful
in salt water disposal lines, crude oil piping, and low pressure
gas gathering systems. Polypropylene has also proved to be an
excellent material for laboratory and industrial drainage where
mixtures of acids, bases, and solvents are involved. Polypropylene is joined by the heat fusion process, threading or flanging.
At 180°F, or when threaded, PP should be used for drainage
only at a pressure not exceeding 20 psi.
PVC — Polyvinyl Chloride Class 12454 conforming to ASTM
D1784. PVC is the most frequently specified of all thermoplastic materials. It has been used successfully for over 40 years
in such areas as chemical processing, industrial plating, chilled
water distribution, deionized water lines, chemical drainage, and
irrigation systems. PVC is characterized by high physical properties and resistance to corrosion and chemical attack by acids,
alkalies, salt solutions, and many other chemicals. It is attacked,
however, by polar solvents such as ketones, some chlorinated
hydrocarbons and aromatics. The maximum service temperature of PVC is 140°F. With a design stress of 2000 psi, PVC has
the highest long-term hydrostatic strength at 73°F of any of the
major thermoplastics being used for piping systems. PVC is
joined by solvent cementing, threading, or flanging.
THERMOPLASTICS & ELASTOMERS
ABS — Acrylonitrile Butadiene Styrene Class 32222 conforming to ASTM D3965 is a time-proven material. The smooth inner
surface and superior resistance to deposit formation makes ABS
drain, waste, and vent material ideal for residential and com-
PVDF — Polyvinylidene Fluoride is a strong, tough and abrasionresistant fluorocarbon material. It resists distortion and retains
most of its strength to 280°F. It is chemically resistant to most
acids, bases, and organic solvents and is ideally suited for handling wet or dry chlorine, bromine and other halogens. No other

Material Definitions
solid thermoplastic piping components can approach the combination of strength, chemical resistance and working temperatures of PVDF. PVDF is joined by the heat fusion process,
threading or flanging.
EPDM — EPDM is a terpolymer elastomer made from ethylenepropylene diene monomer. EPDM has good abrasion and tear
resistance and offers excellent chemical resistance to a variety
of acids and alkalines. It is susceptible to attack by oils and is
not recommended for applications involving petroleum oils,
strong acids, or strong alkalines. It has good ozone resistance.
It is fairly good with ketones and alcohols and has an excellent
temperature range from -20°F to 250°F.
POLYCHLOROPRENE (CR) — Polychloroprenes were one of
the first synthetic rubbers developed. Polychloroprene is an allpurpose polymer with many desirable characteristics and features high resiliency with low compression set, flame resistance,
and is animal and vegetable oil resistant. Polychloroprene is
principally recommended for food and beverage service. Generally, polychloroprene is not affected by moderate chemicals, fats,
greases, and many oils and solvents. Polychloroprene is attacked by strong oxidizing acids, most chlorinated solvents,
esters, ketones, aromatic hydrocarbons, and hydraulic fluids. Polychloroprene has a moderate temperature range of
-20°F to 160°F.
NITRILE (NBR) — BUNA-N is a general purpose oil-resistant
polymer known as nitrile rubber. Nitrile is a copolymer of butadiene and acrylonitrile and has a moderate temperature range of
20°F to 180°F. Nitrile has good solvent, oil, water, and hydraulic fluid resistance. It displays good compression set, abrasion
resistance and tensile strength. Nitrile should not be used
in highly polar solvents such as acetone and methyl ethyl
ketone, nor should it be used in chlorinated hydrocarbons,
ozone or nitro hydrocarbons.
FLUOROCARBON (FKM) — Fluorocarbon elastomers are inherently compatible with a broad spectrum of chemicals. Because of this extensive chemical compatibility, which spans
considerable concentration and temperature ranges, fluorocarbon elastomers have gained wide acceptance as a material of
construction for butterfly valve o-rings and seats. Fluorocarbon
elastomers can be used in most applications involving mineral
acids, salt solutions, chlorinated hydrocarbons, and petroleum
oils. They are particularly good in hydrocarbon service. Fluorocarbon elastomers have one of the broadest temperature ranges
of any of the elastomers, -20°F to 300°F; however, they are not
suited for steam service.
PTFE — Polytetrafluoroethylene has outstanding resistance to
chemical attack by most chemicals and solvents. PTFE has a
temperature rating of -20°F to 400°F in valve applications. PTFE,
a self-lubricating compound, is used as a seat material in ball
valves.
GRAPHITE — Graphite is the packing and seal
material of choice for most fire-rated products, primarily
4
because of its high temperature rating of approximately 2000°F.
Graphite has excellent chemical resistance, can retain compressibility at all temperatures and has a low coefficient of friction. Graphite is not recommended for use in strong oxidizing
atmospheres.
METALS USED IN VALVES & FITTINGS
COPPER — Among the most important properties of wrot copper materials are their thermal and electrical conductivity, corrosion resistance, wear resistance, and ductility. Wrot copper performs well in high temperature applications and is easily joined by
soldering or brazing. Wrot copper is exclusively used for fittings.
BRONZE — One of the first alloys developed in the bronze age
is generally accepted as the industry standard for pressure-rated
bronze valves and fittings. Bronze has a higher strength than
pure copper, is easily cast, has improved machinability, and is
very easily joined by soldering or brazing. Bronze is very resistant to pitting corrosion, with general resistance to most chemicals less than that of pure copper.
SILICONE BRONZE — Silicone bronze has the ductility of
copper but much more strength. The corrosion resistance of
silicon bronze is equal to or greater than that of copper. Commonly used as stem material in pressure-rated valves, silicon
bronze has greater resistance to stress corrosion cracking than
common brasses.
ALUMINUM BRONZE — The most widely accepted disc material used in butterfly valves, aluminum bronze is heat treatable
and has the strength of steel. Formation of an aluminum oxide
layer on exposed surfaces makes this metal very corrosion resistant. Not recommended for high pH wet systems.
BRASS — Generally, brass has good corrosion resistance. Susceptible to de-zincification in specific applications; excellent machinability. Primary uses for wrot brass are for ball valve
stems and balls, and iron valve stems. A forging grade of brass
is used in ball valve bodies and end pieces.
GRAY IRON — An alloy of iron, carbon and silicon, gray iron
is easily cast, and has good pressure tightness in the as-cast
condition. Gray iron has excellent dampening properties and is
easily machined. It is standard material for bodies and bonnets
of Class 125 and 250 iron body valves. Gray iron has corrosion
resistance that is better than steel in certain environments.
DUCTILE IRON — Ductile iron has composition similar to gray
iron. Special treatment modifies metallurgical structure, which
yields higher mechanical properties; some grades are heat-treated to improve ductility. Ductile iron has the strength properties of
steel using similar casting techniques to that of gray iron.
CARBON STEEL — Carbon steel has very good mechanical
properties and is resistant to stress corrosion and sulfides. Carbon steel has high and low temperature strength, is very tough
and has excellent fatigue strength. Mainly used in gate, globe,
and check valves for applications up to 850°F, and in one-, two-,
and three-piece ball valves.

Material Definitions and Standards
3% NICKEL IRON — 3% Nickel iron has improved corrosion
resistance over gray and ductile iron. Higher temperature corrosion resistance and mechanical properties. Very resistant to
oxidizing atmospheres.
NICKEL-PLATED DUCTILE IRON — Nickel coatings have received wide acceptance for use in chemical processing. These
coatings have very high tensile strength, 50 to 225 ksi. To some
extent, the hardness of a material is indicative of its resistance to
abrasion and wear characteristics. Nickel plating is widely specified as a disc coating for butterfly valves.
400 SERIES STAINLESS STEEL — An alloy of iron, carbon, and
chromium, 400 series stainless steel is normally magnetic due to
its martensitic structure and iron content. It is resistant to high
temperature oxidation and has improved physical and mechanical properties over carbon steel. Most 400 series stainless steels
are heat-treatable. The most common applications in valves are
for stem material in butterfly valves and backseat bushings and
wedges in cast steel valves.
316 STAINLESS STEEL — An alloy of iron, carbon, nickel, and
chromium, 316 stainless steel is nonmagnetic with more ductility
than 400SS. Austinetic in structure, 316 stainless steel has very
good corrosion resistance to a wide range of environments, is
not susceptible to stress corrosion cracking and is not affected
by heat treatment. Most common uses in valves are stem, body
and ball materials.
630 STAINLESS STEEL — 630 stainless steel is a martensitic
precipitation/age hardening stainless steel, offering high strength
and hardness. 630 SS withstands corrosive attack better than
any of the 400 series stainless steels, and in most conditions
its corrosion resistance closely approaches that of 300 series
stainless steel. 630 SS is primarily used as a stem material for
butterfly and ball valves.
