DETAILS

Ideal for building up on carbon and low alloy steels. Use as an underbase for carbon steel parts prior to hardfacing. Great compressive strength under heavy loading. Deposits are generally crack free, machinable and can be flame cut. Deposit thickness is unlimited.

Features

  • Delivers deposits with moderate hardness for build-up or as final overlay
  • Provides some resistance to metal-to-metal wear and moderate impact
  • Unlimited layers with proper preheat and interpass temperatures and procedures

Typical Applications

  • Rolls
  • Shafts
  • Pump and shovel parts
  • Pulverizer
  • Plows

Welding Positions

  • Flat/Horizontal

Shielding Gas

  • 75-90% Argon/Balance CO2; 98% Argon/2% O2
