Alloy 310 / 310S - Weldability

Back To Weldability Alloys

Alloy 310/310S is promptly fabricated by a standard commercial process. In comparison to carbon steel, stainless steels are tougher and tend to work harden quickly. By using all of the common welding processes Alloy 310/310S can be easily welded. By using fusion or resistance technique most of the austenitic stainless steels can be quickly welded. Oxyacetylene welding is not suggested. Filler metal should be AWS E/ER 310.
