Stainless Steel AISI 316L

Data sheet
DIN EN 10088-3
Grade AISI 316L / EN 1.4404

AISI 316L / EN 1.4404 is an austenitic stainless steel with very good corrosion resistance. This stainless steel grade has very low magnetizability, excellent welding properties and is suitable for cold forming. The material can be used at temperatures up to 550 °C.
The processing possibilities include cold heading and polishing.
