Stainless steel is a versatile material comprised of a steel alloy and a small percentage of chromium — the addition of chromium adds to the material’s corrosion resistance, a trait that earned stainless steel its name. Because stainless steel is also low-maintenance, oxidation resistant, and doesn’t affect other metals it comes in contact with, it is frequently used in a large array of applications, especially in piping and tubing manufacturing.

Material stainless steel grades


ASTM A312 is a specification for seamless, welded, and heavily cold-worked austenitic stainless steel pipes intended for high-temperature and general corrosive service. The standard covers grades TP304, TP304L, TP316, TP316L, TP317, TP321, and TP347, among others. These pipes are widely used in various industries such as petrochemical, food processing, pharmaceuticals, and power generation due to their excellent corrosion resistance and high-temperature strength. The specification also covers various types of fittings and flanges made from these materials.
