Welded Square Stainless Steel Tube Specification :
Stainless steel square tube is a kind of hollow long steel, because the section is square, it is called square tube. A large number of tubes are used for conveying fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending resistance and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.
Our Welded stainless steel square tube meets ASTM A554 standard specification.
