Identification method of stainless steel channel

Stainless steel channel is a long strip of steel with a cross-sectional shape. Hot rolled stainless steel ordinary channel is mainly used for building structures, vehicle manufacturing and other industrial structures, often used in conjunction with I-beam. Hot-rolled stainless steel light channel is a kind of thin steel wall, than the ordinary hot-rolled channel has a better economic effect. Stainless steel channel steel are: 201,202,301,304,321,316,316 L, special materials can generally be customized.

Number and representation of channel
① with the international chemical elements and symbols of the country to represent the chemical composition, with Arabic letters to represent the content of ingredients: such as: China, Russia 12CrNi3A;
② with a fixed number of digits to represent the steel series or figures; such as: the United States, Japan, 300 series, 400 series, 200 series;
③ use the Latin alphabet and order to form the serial number, only that use.

The numbering rules of our country
① use element symbols;
② use, Chinese Pinyin, flat furnace steel: P, boiling steel: F, sedative steel: B, a class steel: A, T8: special 8, GCr15: ball;
◆ composite steel, spring steel, such as: 20CrMnTi 60SiMn, (with a few points that C content);
◆ stainless steel, alloy tool steel (with a few thousandths of said 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 0Cr17Ni13Mo.

International stainless steel marking method
The American Society of Iron and Steel is using three digits to mark a variety of standard grade wrought stainless steel. among them:
① austenitic stainless steel with 200 and 300 series of digital signs;
② ferrite and martensitic stainless steel with 400 series figures. For example, some of the more common austenitic stainless steels are marked with 201, 304, 316 and 310;
③ ferritic stainless steel is marked with 430 and 446, martensitic stainless steel is 410,420 and 440C as the mark, biphasic (austenite – ferrite);
④ stainless steel, precipitation hardening stainless steel and iron content of less than 50% of the high alloy is usually named after the patent name or trademark.
