SelectWear BU-S

Hardsurfacing / Submerged Arc / Flux Shielded

Resources

Features

  • Deposits a low alloy steel with good compressive strength designed as either an underlay for further hardfacing, or as the final layer for low stress metal-to-metal wear applications
  • To be used on carbon and low alloy steels
  • Unlimited layers can be deposited with proper welding procedure
  • Applications include: Continuous rolls, shafts, wheels (mine cars, cranes, etc.), pulleys, cast steel wear parts
  • The softest of our submerged arc build-up products (BU24-S and BU30-S being the other options)
