AISI 403 / 410S | EN 1.4000 | DIN X6Cr13

Ferritic stainless steel EN 1.4000 | AISI 403 / AISI 410S | DIN X6Cr13 with a small addition of aluminum minimizes the formation of austenite at high temperatures, thereby limiting the hardening ability of the alloy. The result is a soft, plastic state when the material is cooled sharply above the critical temperature.
