General
Description
For carbon and low alloy steels. Builds up worn steel parts to produce tough, forgeable,
machinable surfaces of moderate hardness.
Moderate hardness to resist shock. Used as final overlay on parts which must be machined
or forged. For mild, medium carbon, low alloy and high tensile steels.
Martensitic deposit. Heat treatable weld metal. Can be tempered, annealed. Can be used on
carbon and low alloy steels.
Provides wear-resistant surface of martensite, with substantial retained austenite. Resists
metal-to-metal wear, impact, mild abrasion. Can be used on carbon and low alloy steels.
Excellent abrasion resistance. Fuses to carbon, low alloy, stainless, and manganese steel.
Limit 2 layers. Use Wearshield BU, Mangjet
®
Resists very severe abrasion at temperatures up to 1400°F (760°C). Use with mild, low alloy,
stainless and austenitic manganese steels. Limit 2 layers.
Use on carbon and low alloy steels, cast iron, austenitic manganese and austenitic stainless
steels. Use Wearshield ® BU or 15CrMn for preliminary layer(s).
EO = Easy Open Hermetic Can
