Economic function of TP 304 / Ss304 stainless steel pipe

The export of TP 304 / Ss304 stainless steel seamless pipe is an important part of China's export economy and plays an important role in stimulating China's economic growth. However, China's stainless steel foreign trade has encountered great resistance to China's export of stainless steel.

TP 304 / Ss304 stainless steel pipes are used as stainless steel pipes for food equipment, conventional chemical equipment and equipment in the atomic energy industry.

Stainless steel has stronger rust resistance than 200 series stainless steel materials. It is also suitable for high temperatures, up to 1000-1200 degrees. TP304 / SS304 stainless steel has excellent corrosion resistance and good corrosion resistance.

304 stainless steel material has a strong resistance to nitric acid corrosion, lower than the boiling temperature and lower than 65%. Alkaline solutions and most organic and inorganic acids also have good corrosion resistance.

Performance analysis:

TP304 / SS 304 stainless steel pipe has good corrosion resistance, excellent corrosion resistance, cold working and stamping properties, and can be used as heat-resistant stainless steel. At the same time, steel will have this frustrating disease of mechanical properties at -180°C. The plasticity, toughness and cold workability of solid solution steel are good. The production and use of 304 stainless steel is the largest and most widely used steel grade, which can resist the corrosion of dielectric acid, atmosphere and water.

TP304 / SS304 stainless steel has good hot and cold processing performance, which can be used in various cold and hot processing processes.

Heat treatment process

The solution treatment temperature of 304 stainless steel pipe is 1080-1100℃, and it can be cooled by cooling water or air. The cold intermediate annealing temperature exceeds 850-970℃, add water after holding for a certain period of time. After solid solution, the structure of steel is austenite, sometimes there is a small amount of ferrite.

TP304 / SS304 stainless steel sheet is used in the application process, usually used in cold forming operations. Its cold forming performance is an important technical indicator to measure the success of forming.
