Electrode Hardness General
Name Rockwell C Description
Build-Up
Wearshield ® BU 23-28 For carbon and low alloy steels. Builds up worn steel parts to produce tough, forgeable,
machinable surfaces of moderate hardness.
Wearshield ® BU-30 31-38 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.
Metal-To-Metal Wear
Wearshield ® MM 52-58 Martensitic deposit. Heat treatable weld metal. Can be tempered, annealed. Can be used on
carbon and low alloy steels.
Wearshield ® MI 50-58 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.
Severe Abrasion
Wearshield ® 60 60-65 Excellent abrasion resistance. Fuses to carbon, low alloy, stainless, and manganese steel.
Limit 2 layers. Use Wearshield
® BU, Mangjet ® or 15CrMn for preliminary layer(s).
Wearshield ® 70 69 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.
Metal-To-Earth
Wearshield ® ME 49-59 Use on carbon and low alloy steels, cast iron, austenitic manganese and austenitic stainless
steels. Use Wearshield
® BU or 15CrMn for preliminary layer(s).
