SelectWear BU24-S

Hardsurfacing / Submerged Arc / Flux Shielded

Resources

Features

  • Deposits a low alloy steel with good compressive strength designed as an underlay for further hardfacing, or the final layer for low stress metal-to-metal wear applications.
  • To be used on carbon and low alloy steels
  • The intermediate hardness level of our build up alloys, with SelectWear BU-S being softer and BU30-S being harder
  • Applications include: steel mill rolls, shafts, mine car wheels, pulleys, cast steel wear parts
