410 stainless steel bar is a martensitic (high-strength chromium steel) stainless steel with good corrosion resistance and machinability. It is generally used as steel and cutting tool steel, and its UNS number is S41000.

304 is a common stainless steel material, the main components of which are 18% chromium and 8% nickel. 2B refers to the surface treatment method of stainless steel plate.

ASTM A312/A312M-09 This specification covers seamless, straight-seam welded, and heavily cold-finished welded austenitic stainless steel pipe for high-temperature and generally corrosive service.

310S stainless steel tubes have more nickel than 304 stainless steel tubes, so they have better high temperature resistance.

TP316L electropolished pipes are manufactured to ASTM A269/A270/A632, ASME BPE, JIS G3459, ISO1699 and TS16949 standards.

304 stainless steel plates are available in both hot-rolled and cold-rolled forms. The main difference lies in the temperature control during processing and the subsequent performance characteristics.
