Which is better pressure-bearing, 201 stainless steel pipe or 304 stainless steel pipe

The difference between stainless steel pipe 201 and 304 pressure bearing is that 201 stainless steel is higher in terms of strength (pressure).

Due to the high content of Mn (manganese) in 201 stainless steel pipes and the high carbon content in 201 stainless steel pipes, these two alloys determine the strength (pressure-bearing, mechanical comprehensive performance is better than that of 201 stainless steel pipes.

Stainless steel pipes. However, the corrosion resistance of 304 stainless steel pipe is two grades higher than that of 201 stainless steel pipe, and there is stainless steel 301 in the middle.

304 stainless steel pipe is higher than 201 stainless steel pipe in terms of strength (pressure). The comprehensive mechanical performance of 304 stainless steel pipe is better, and its tensile strength and corrosion resistance are better than that of 201 stainless steel pipeDuring processing, 304 stainless steel pipes are relatively soft, generate less stress, and the risk of weld bead cracking is 35% lower than that of 201 stainless steel pipesIn addition, 304 stainless steel tubing can be annealed solution treatment, while 201 stainless steel tubing rarely undergoes this treatmentThe annealed stainless steel pipe can increase the pressure stability of 20Mpa, which further improves the pressure bearing capacity of the 304 stainless steel pipeTherefore, in situations where high loads and pressures need to be withstanded, 304 stainless steel pipes are more reliable
