About 201 stainless steel square pipe

201 square pipe is a hollow steel strip, because the cross section is square, so called square. Used as fluid piping such as oil, gas, water, gas, steam, etc.. In addition to bending, torsional strength and light weight, so use in a wide range of parts manufacturing and engineering structure. Do the barrel of conventional weapons, etc..

201 stainless steel tube is a stainless steel plate, stainless steel belt, stainless steel coil material after the cold bending process after the high-frequency welding square cross-section shape made of steel. In addition to hot tube wall thickness thickening, corner edge size and flatness has reached the highest level.
