Select 4130C
Low Alloy / Metal Cored / Gas Shielded
Features
- Can be used for welding 4130, 4140, 8630, and similar alloy steels that are to be post weld heat treated.
- This electrode was designed to meet the properties of quenched and tempered steels, and therefore should not be used for as-welded applications.
- The recommended shielding gas is 98%Ar / 2%O₂, however, 90%Ar / 10%CO₂ may be used as well.
- Contains less than 1% nickel, making this electrode suitable for most sour service applications.
