Stainless Steel 321H ERW Pipes

Stainless Steel 321H ERW Pipes

The chemical composition of SS 420 ERW pipes typically includes 12.0-14.0% chromium, 0.15% carbon, 1.0% manganese, 1.0% nickel, 0.04% phosphorus, 0.03% sulfur, 0.6% silicon, and traces of molybdenum and aluminum. The addition of chromium provides good corrosion resistance, while nickel and molybdenum enhance the strength and hardness of the steel. This steel is commonly used to produce cutting tools, surgical instruments, and pump components. Its combination of good corrosion resistance, high hardness, and good formability make it a popular choice for various applications.

Stainless steel 321H ERW pipes are widely used in areas requiring high-temperature strength and corrosion resistance. They are used to manufacture many industrial components such as heat exchangers, pressure vessels, boilers, tanks, etc. These pipes are also used in the transport of oil and gas and the construction of pipelines. The properties of stainless steel 321H ERW pipes include high-temperature strength, excellent corrosion resistance, and good formability. They resist oxidation and carburization at high temperatures and have a lower thermal expansion rate. They are also non-magnetic and offer good weldability and machinability. The combination of these properties makes stainless steel 321H ERW pipes an ideal choice for applications in extreme environments.

Stainless Steel 321H ERW Pipes FAQ's  

321H Erw pipes are widely used in high-temperature and corrosive environments, such as heat exchangers, boilers, petrochemical and nuclear power plants, oil refineries, and chemical processing industries.

321H Erw pipes have high strength, good ductility, good weldability, and good resistance to intergranular corrosion. They also have good resistance to oxidation and have high resistance to stress corrosion cracking.

321H Erw pipes have a higher nickel and chromium content compared to 304 and 316 stainless steel pipes, which makes them more resistant to corrosion and oxidation in high-temperature environments.
