AISI 410 stainless steel X12Cr13 DIN 1.4006 SUS410 coils

AISI 410 (UNS S41000), X12Cr13 (DIN 1.4006), and SUS410 are cross standard designations for the same martensitic stainless steel, all containing 11.5% -13.5% chromium and low carbon (≤ 0.15%), with corrosion resistance, wear resistance, and heat treatment strengthening properties. The chemical composition and basic properties of the three are consistent, but the scope of application of the standards is different: AISI and SUS are commonly used grades in the United States and Japan, while DIN 1.4006 is a European standard applicable to semi-finished products such as steel coils and plates.

After quenching and tempering, the hardness of the material reaches HRC 35-45, and the tensile strength is ≥ 515 MPa. In the cold-rolled state, annealing is required to improve the processing performance. DIN 1.4006 emphasizes the dimensional tolerances of hot-rolled coils, SUS410 refines the surface treatment requirements under JIS standards, and AISI 410 is mostly used in industrial equipment and tool manufacturing.

AISI 410 steel coil is widely used in automotive components, pumps and valves, and food machinery. When selecting materials, it is necessary to consider regional standards and working conditions. Attention: DIN 1.4006 imposes stricter restrictions on sulfur and phosphorus impurities. Welding requires preheating and controlled cooling rate to avoid performance deviations due to standard differences.
