PRODUCT OVERVIEW
Vecalloy 800 has been specifically designed as a
Manganese steel compatible hardfacing overlay.
In many mining processes where Manganese
steel is used, the steel is gouged or wears away
before it has a chance to work harden.
Vecalloy 800 is welded as a hardfacing overlay
that protects the Manganese steel substrate from
extreme abrasion, while giving it a chance to
work harden as it was designed to do.
Vecalloy 800 is patent pending.
DESIGN APPROACH
The design process for Vecalloy 800 and all SCOPERTA materials involves a proprietary high
throughput computational metallurgical process to evaluate millions of candidate alloy compositions.
Potential candidates are then experimentally evaluated using an advanced screening process where
both properties and alloy microstructure are measured.
The combined computational and experimental approach allows SCOPERTA to rapidly design the final
material with a much better accuracy than conventional experiment-based methodologies.

WEAR AND IMPACT PERFORMANCE
Vecalloy 800
at
1,000X
With an ASTM of G65 of 0.36 grams of mass
loss, Vecalloy 800 exhibits superior wear
performance compared to traditional Manganese
steels.
The wear performance of Vecalloy 800 will
increase the lifetime of the product, while
providing the ductility to enable the work
hardening of the Manganese steel substrate.
WORK HARDENABILITY
Due to the high Manganese content and the austenitic matrix, Vecalloy 800 will typically work harden up to
63-65 HRC under impact, providing greater wear resistance the longer the overlay is in service.

PREVENTING DEFORMATION
Vecalloy 800 does not deform as drastically as As-Cast Manganese steel does. Vecalloy 800 will protect
Manganese steel substrate from deformation in high stress environments.

CRACK RESISTANCE
Vecalloy 800 was designed using fine, dispersed carbides preventing the propagation of cracks through the
coating when welded on Mn steel. Not only does the crack resistance lead to the superior impact
performance, but it prevents cracks from forming during the welding process.
Since no cracks form during the welding process, Vecalloy 800 can be welded as a double-layer overlay
without fear of underbead or lateral cracking.

SUGGESTED APPLICATIONS
Vecalloy 800 coatings are suggested for use in
any Manganese steel applications where
improved abrasion resistance is required. The
revolutionary improvement in abrasion and
impact for an as-welded Manganese steel overlay
will lead to longer lifespans for Manganese steel
plates in the mining industry.
