High-Performance Mild Steel TIG Welding Rod. SAE 4140 TIG welding rod. AISI: 4140 grade. Class: 4140. SAE4140 is a low alloy, 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. 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 (Mild steel tig welding rod - sae 4140-1/16"- 1LB. pack was posted and is owned by: Jared Gill) |
