304 stainless steel pipe can be used in general chemical equipment, atomic energy industrial equipment.
The anti-rust performance of 304 stainless steel is stronger than that of 200 series stainless steel. High temperature resistance is also good, can be as high as 1000-1200 degrees. 304 stainless steel has excellent stainless corrosion resistance and good resistance to intergranular corrosion.
304 stainless steel material has strong corrosion resistance in nitric acid below the boiling temperature of ≤ 65%. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids. A high alloy steel alloy steel that resists corrosion in air or chemically corrosive media.

Manufacturing process：
Round tube billet → heating → perforation → head → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → blank tube → heat treatment → straightening → hydraulic test (inspection) → mark → in Library.
