410 stainless steel is produced according to U.S. ASTM standard grades of stainless steel, equivalent to our 21Cr13 stainless steel, S41000 (U.S. AISI, ASTM). Containing 0.01% carbon, 0.13% chromium, 410 stainless steel: good corrosion resistance, mechanical processing, general purpose blade type, valve type. 410 stainless steel heat treatment: solution treatment (℃) 800-9000 750 slow cooling or fast cooling. 410 stainless steel chemical composition: C ≤ 0.15, Si ≤ 1.00, Mn ≤ 1.00, P ≤ 0.035, S ≤ 0.030, Cr = 11.50 ~ 13.50

International Stainless Steel labeling method
  American Iron and Steel Institute is a three-digit number used to mark a variety of standard-grade stainless steel can be forged. Of which:
  ① austenitic stainless steel with 200 and 300 series digital mark,
  ② ferritic and martensitic stainless steel 400 series with a digital representation. For example, some of the more common austenitic stainless steel
  Is 302, 304, 316 and 310 for the mark,
  ③ ferritic stainless steel is marked 430 and 446, and 440C martensitic stainless steel as standard is based on 410,420
  Remember, two-phase (austenite - ferrite),
  ④ stainless steel, precipitation hardening stainless steel, and iron content of less than 50% of high alloy is often used proprietary name or trade name.
  The number and representation of steel
  ① chemical element with the symbol of international and national symbols to represent the chemical composition, with the Arabic alphabet to represent the components of content:
  Such as: China, Russia 12CrNi3A
  ② with a fixed number of digits to represent the number of steel series or class; such as: USA, Japan, 300 series, 400 series, 200 series;
  ③ the order form with the Latin alphabet and numbers, saying only that purpose.
