SAE 4130

High-Performance Mild Steel TIG Welding Rod.

Approximate number of rods per 1 lb. pack for each diameter:

• .035" (0.89mm): 50 - 54
• .045" (1.14mm): 36 - 40
• 1/16" (1.6mm): 26 - 30
• 3/32" (2.4mm): 12 - 16
• 1/8" (3.2mm): 8 - 10

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.
