410 Stainless Steel 
 410 stainless steel is produced in accordance with the ASTM standard grades of stainless steel, equivalent to China's 21Cr13 stainless steel, S41000 (U.S. AISI, ASTM). Containing carbon 0.01%, 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 Society of stainless steel marking method is to use the United States to mark a variety of standard three-digit level of malleable stainless steel. Including: 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 430 and 446 for the tag, and 440C martensitic stainless steel is 410,420 for the mark, phase (austenite - ferrite), ④ stainless steel, precipitation hardening stainless steel and iron content of less than 50% of high-alloy often used the name or trademark patent 

 Name. Steel number and representation ① chemical element with the symbol of international and national symbols to represent the chemical composition of the Arabic alphabet to represent the component content: such as: China, Russia 12CrNi3A ② fixed number of digits to represent the steel class series or digital; as : United States, Japan, 300, 400 series, 200 series; ③ order form with the Latin alphabet and numbers, saying only that purpose
