ASTM 317L - EN 1.4438 - Austenitic Stainless Steel - Stainless steel

ASTM 317L - EN 1.4438

Alloy 317L is an ultra-low carbon adaptation of the 317 chromium-nickel austenitic variety. It integrates molybdenum, which enhances overall corrosion protection and increases resistance to pitting in chloride-containing solutions. It is not magnetic in the annealed state and can't be hardened through heat treatment, yet it will harden with cold working.
