SAE 4130 - AISI 4130

SAE4130 is a low alloy, copper-coated wire designed for the welding of heat-treatable, low alloy steels such as the SAE / AISI 4100 or 8630 series, as well as steel castings with similar hardening characteristics.

A pre-heat of 300°F - 350°F is required for some of the higher carbon grades to prevent cracking.

Many other grades can be welded without preheat.

Proper heat-treating procedures will produce tensile strengths of 150,000 - 160,000 psi.

(Rods priced per lb, sold in 10 lb boxes)
