2 Reveal the steel series or numbers with the digits of static digits; for example, the United States, Japan, 300 series, 400 series, 200 series;
3 Use Latin letters and steps to form a serial number, only to reveal the use.
China's numbering and delimitation rules 1 The use of element identification logos 2 uses, Pinyin, open hearth steel: P, boiling steel: F, busy steel: B, A steel: A, T8: special 8, GCr15: ball â—†Mixed steel, spring steel, such as: 20CrMnTi 60SiMn, (express C content in several ten thousandths)
◆ stainless steel, alloy east-west steel (with a few thousandth reveal C content), such as: 1Cr18Ni9 one thousandth (ie 0.1% C), stainless steel C ≤ 0.08% such as 0Cr18Ni9, ultra-low carbon C ≤ 0.03% such as 00Cr17Ni13Mo
Outer Stainless Steel Marking Method The American Iron and Steel Institute uses three digits to indicate various types of standard grade wrought stainless steel. Here are:
1 Austenitic stainless steel is marked with 200 and 300 series numbers.
2 Ferritic and martensitic stainless steels are revealed with 400 series numbers. For example, some of the more mediocre austenitic stainless steels 201, 304, 316, and 310 are labeled 3 Ferritic stainless steels and thus 430 and 446 are marked signs, and martensitic stainless steels are therefore 410, 420, and 440C for marking, duplex (austenitic-ferritic),
4 Stainless steels, precipitation hardened stainless steels, and high alloys with less than 50% iron content are usually named after patent titles or trademarks.
