SelectWear 8620-S

Hardsurfacing / Submerged Arc / Flux Shielded

Resources

Features

  • Deposits a low alloy steel designed for the buildup of carbon and low alloy steels, especially AISI 8620 steel.
  • Provides a tough underlayment upon which subsequent hard facing layers may be deposited, particularly in steel mill roll applications.
  • Excellent compressive strength, and can also be used in some low stress metal-to-metal abrasion situations.
  • Typical applications include steel mill rolls, shafts, wheels, and drums.
  • Unlimited layers can be deposited with proper welding procedures.
  • Deposit has good machinability and will not cross crack.
  • Neutral fluxes are recommended.
