CLASSIFICATION: No AWS Class

Select 4130C is the metal cored version of Select 4130LN. This electrode is designed to match the properties of certain quench and tempered steels following post-weld heat treatment. It is not recommended for as-welded applications.

APPLICATIONS: Select 4130C is ideal for welding 4130, 4140, 8630 and similar alloy steels that are to post-weld heat treated. The weld deposit contains less than 1% nickel making it suitable for most oilfield applications.

DIAMETERS: .045", 1/16"

SHIELDING GAS: 98% Ar/2% O2

WELDING POSITIONS: Flat and Horizontal

CHARACTERISTICS:

  • Provides weld metal properties that closely match those of certain quench and tempered steels in the heat treated condition.
  • Smooth arc transfer with minimal spatter.
  • Contains less than 1% nickel in the weld deposit.
