Stainless steel round pipe: with a variety of stainless steel hot rolled, cold rolled stainless steel pipe, widely used in petroleum, chemical equipment pipelines and various uses of stainless steel structure parts, in addition to ensure chemical composition and mechanical properties, where used to withstand fluid pressure steel pipe to ensure that the hydraulic test qualified. All kinds of special steel pipes should be guaranteed according to the specified conditions.
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.
