Alloy 410 - SS Weldability

Back To Weldability Alloys

Using all standard techniques Grade 410 can be easily welded, but the materials should pre-heated at 150 to 260°C followed by post-weld annealing treatment, to reduce cracking. For tempering and post-hardening Grade 410 welding rods are suggested. In the "as welded" conditions, grade 309 filler rods can be utilized to achieve a ductile joint. As per AS 1554.6 standards, grade 309 electrodes or rods are approved for welding 410 stainless steels.
