Stainless Steel AISI 314
Data sheet
DIN EN 10095
Grade AISI 314 / EN 1.4841
AISI 314 / EN 1.4841 is an austenitic stainless steel which has good heat resistance and strength at high temperatures. The scaling resistance is increased by the silicon content of 1.5 - 2.00 % to about 1150°C (in air). 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.
