Mild steel tig welding rod - sae 4130 - 1/8"- 1LB. pack
High-Performance Mild Steel TIG Welding Rod. SAE 4130 TIG welding
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.
