Stainless Steel AISI 310S

AISI 310S Stainless Steel Data Sheet

Data sheet
DIN EN 10095
Grade AISI 310S / EN 1.4845


AISI 310S / EN 1.4845 is an austenitic stainless steel which has good heat resistance and strength at high temperatures. The resistance to scaling in air is 1050°C (for higher temperatures we recommend the material AISI 314 / EN 1.4841). This stainless steel grade is well suited for welding, forging and cold forming.
Typical areas of application are in apparatus engineering, furnace construction or the chemical industry.
