Note: Rods per pack is an approximate and varies on metal type.

SAE 4140 - AISI 4140

SAE4140 is a low alloy, metal-cored (not copper coated) wire designed for the welding of heat-treatable, low alloy steels such as the SAE / AISI 4100 series where higher carbon grades are used or where greater tensile strengths are required.

4140 is a metal cored wire designed for welding and build up on mild & low alloy steels having a smooth stable arc transfer, spatter free, excellent bead contour, with a high deposition rate and nearly free of slag weld bead.

This wire is formulated to weld flat and horizontal which has deoxidizers that helps where mill scale may be present.

This metal cored wire is typical used on dies, forgings, castings and other base metals where heat treating is required.

Preheat and interpass of 500-650° F is found on AISI 4140 grades of base metal followed by slow cool and post weld heat treating to required hardness.

A pre-heat of 375°F - 450°F is required for some of the higher carbon grades to prevent cracking.

Proper heat-treating procedures will produce tensile strengths of 175,000 - 200,000 psi.

Hardness varies with heat-treating.
