316 stainless steel square pipe

316 stainless steel square tube, the middle of the hollow. Because there is a square cross section so called square tube. Mostly used in the transmission of gas and liquid pipes, such as water, gas, oil, natural gas, steam and so on. And in the same bending, torsional strength, lighter than the average material. So in the engineering structure and machinery manufacturing is also widely used.

316 stainless steel contains Mo element, can greatly improve the high temperature and corrosion resistance of stainless steel. High temperature up to 1200-1300 degrees. 316 stainless steel corrosion resistance is much higher than 304 stainless steel, in the paper and pulp production process has a good corrosion resistance. And 316 stainless steel can resist the erosion of the erosive industrial atmosphere.

316 stainless steel also has excellent welding performance, need to be annealed after welding.
