ASTM A789 covers standard requirements for grades of nominal wall thickness,Duplex Best Stainless Steel Pipes for services requiring general corrosion resistance, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures. Heat and product analyses shall be performed wherein the steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, nitrogen, copper, and others. All tubes shall be furnished in the heat-treated condition in accordance with the specified temperature and quenching conditions.
When the final heat treatment is in a continuous furnace, or when heat treated condition is obtained directly by quenching after hot forming, the number of tubes of the same size and from the same heat in a lot shall be determined from the prescribed sizes of the tubes. The material shall conform to the prescribed tensile and hardness properties. Mechanical tests such as tension tensile strength test, flaring test for seamless tubes, flange test for Duplex Best Stainless Steel Pipes, hardness test, and reverse flattening test shall be performed on the stainless steel tubing. Each tube shall also be subjected to the nondestructive electric test or the hydrostatic test.
This covers grades of nominal wall thickness,Duplex Best Stainless Steel Pipes for services requiring general corrosion resistance, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures.
