 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. 
 Number of rules in China 
 ① using element symbols 
 ② use Hanyu Pinyin, open-hearth steel: P, boiling steel: F, killed steel: B, A Steel: A, T8: Special 8, 
 GCr15: Ball 
 ◆ structural steel, spring steel, such as: 20CrMnTi 60SiMn, (with very few that C content) 
 ◆ stainless steel, alloy tool steel (with a few thousandths of said C content), such as: 1Cr18Ni9 thousandth (ie, 
 0.1% C), such as stainless steel C ≤ 0.08% 0Cr18Ni9, ultra-low carbon C ≤ 0.03% as 0Cr17Ni13Mo
