AISI 405 | EN 1.4724 | DIN X10CrAlSi13 is a ferritic stainless steel supplemented with aluminum. It is characterized by resistance to sulfur-containing gases. The steel is heat-resistant: resistant to temperatures of 950 °C in air. Due to the low chromium content, EN 1.4724 is not as resistant to high-temperature oxidation as EN 1.4742.

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.
