Directory of stainless steel grades

AISI 306 | EN 1.4361 | DIN X1CrNiSi18-15-4 is an austenitic stainless steel developed for primary forming into forged products. It is used for parts exposed to hot concentrated nitric or sulfuric acid. It is resistant to intercrystalline corrosion, which develops in very concentrated (over 90%) nitrogen environments up to the boiling point.

AISI 317LMN | EN 1.4439 | DIN X2CrNiMoN17-13-5 - austenitic stainless steel which is an improved austenitic version of steel grades AISI 316 and AISI 317. It has a higher content of nickel, molybdenum and nitrogen in its composition, which significantly increases the product's resistance to pitting and crevice corrosion.
