Worldwide equivalents of grade 410 stainless steel (USA: AISI, ASTM, UNS)

Grade 410 stainless steel corresponds to a unified material in AISI, ASTM, and UNS standards. AISI 410 (UNS S41000) is the basic grade, while ASTM A240's 410 type refines the plate specifications, with a composition of 11.5% -13.5% chromium and low carbon (≤ 0.15%). The performance of the three is consistent, ensuring strength, corrosion resistance, and universality of heat treatment processes.

AISI focuses on material classification, ASTM A240 specifies the mechanical properties (such as tensile strength ≥ 515 MPa) and processing requirements of sheet metal, and UNS S41000 serves as a cross standard unified code to simplify global supply chain matching. All three are martensitic stainless steels, but ASTM specifies additional welding and heat treatment details to enhance their applicability.

410 stainless steel material is widely used in valves, cutting tools, and industrial equipment, and its cross standard equivalent characteristics make it interchangeable for use. Attention: ASTM A240 supplements environmental restrictions (such as high chloride ion protection), and actual material selection should be based on working conditions and regulatory requirements to ensure compatibility.
