AISI 442 | EN 1.4742 | DIN X10CrAlSi18 is a heat-resistant ferritic chromium stainless steel with the addition of aluminum. It is characterized by resistance to sulfur-containing gases. Due to the higher chromium content, it is more resistant to high-temperature oxidation than EN 1.4724, but less resistant than EN 1.4762, which contains even more chromium.

AISI 303 | EN 1.4305 | DIN X8CrNiS18-9 is an austenitic, corrosion-resistant stainless steel with the addition of sulfur to improve cutting properties (randomly machined steel). Its corrosion resistance is limited in acidic and chloride environments. When used in such environments, pitting or strip corrosion may occur.

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.
