210 304 310 Stainless Steel Round Seamless Pipe

Stainless steel pipe is a kind of hollow long circular steel, widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipeline and mechanical structure parts. In addition, in bending, torsional strength is the same, light weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture, kitchenware, etc.

301----- Good malleability for molding products. It can also be machined to harden rapidly. Good weldability. The wear resistance and fatigue strength is better than 304 stainless steel.

304----- is 18/8 stainless steel. The GB brand is 0Cr18Ni9. 309 -- has better temperature resistance than 304.

316----- The second most widely used steel after 304, mainly used in the food industry, pharmaceutical industry and surgical equipment.

321 -- Similar in properties to 304 except that titanium is added to reduce the risk of corrosion in the material weld.

410 -- martensite (high strength chromium steel), good wear resistance, poor corrosion resistance.

420 -- "tool grade" martensitic steel, similar to Brinell high chromium steel this earliest stainless steel. Also used in surgical knives, can be made very bright.
