Labeling method

The American Iron and Steel Institute is using three digits to label the various standard grades of malleable stainless steel ground. Among them.
1.austenitic stainless steel with 200 and 300 series of numbers indicated.
2.ferritic and martensitic stainless steel with 400 series of numbers.
For example, some of the more common austenitic stainless steels are marked with 201, 304, 316, and 310, ferritic stainless steels are marked with 430 and 446, martensitic stainless steels are marked with 410, 420, and 440C, duplex (austenitic-ferritic) stainless steels, precipitation hardening stainless steels, and high alloy with less than 50% iron content Usually a patented name or trademark name is used.

product description

Stainless steel pipe is a kind of hollow round steel strip, which is widely used in industrial pipelines and mechanical structural parts of petroleum, chemical, medical, food, light industry, machinery and instrumentation. In addition, it is light in weight when the bending and torsional strengths are the same, so it is also widely used in the manufacture of mechanical parts and engineering structures. It can also be used as furniture and kitchenware.
