AISI 431 | EN 1.4057 | DIN X17CrNi16-2 is a rust- and acid-resistant martensitic chromium steel with the addition of nickel. The formation of chromium carbides and associated chromium-depleted areas makes this grade susceptible to intercrystalline corrosion. It cannot be cold worked because the grade has a high yield strength.

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.
