Stainless Steel AISI 302
Data sheet
DIN EN ISO 6931-1
Grade AISI 302 / 1.4310
Grade AISI 302 / 1.4310 is an austenitic stainless steel with a high content of chromium and nickel. A typical application for this stainless steel grade is the industrial production of springs. The material AISI 302 / 1.4310 is suitable for cold forming and owns good polishing qualities.
Please note that the magnetizability changes due to cold forming.

Welding
Since the stainless steel material 1.4310 / AISI 302 is a stainless spring steel wire, this stainless steel material cannot be welded or only with great effort. The very poor welding properties of the material 1.4310 / AISI 302 are primarily due to the high carbon content.
We advise you to use our CEV calculator to assess the weldability.
