Stainless Steel 321H Pipe Fittings Supplier

Stainless Steel 321/321H Pipe Fittings are electric-furnace austenitic steels that are non-heat treatable and non-magnetic in their annealed condition. These fittings contain nickel, chromium, and titanium as actual contents, making them an ideal choice for various applications and industries. Their properties include high tensile strength, durability, weldability, long functional life, and corrosion resistance. They can withstand running temperature atmospheres and possess good low-temperature toughness.

Properties:
The high carbon content of Stainless Steel 321/321H Pipe Fittings offers excellent resistance to general corrosion and chemical attack environments while improving high-temperature strength. These Pipe Fittings provide good creep resistance and higher strength at elevated temperatures. They are non-magnetic and have excellent tensile strength, weldability, robust construction, higher durability, flexibility, and longer functional life. They provide intergranular corrosion attack and offer outstanding strength and corrosion resistance to stress corrosion cracking and pitting crevices similar to Stainless Steel 317 Seamless Fittings.

Composition:
Stainless Steel 321/321H Pipe Fittings combine carbon, manganese, silicon, phosphorus, sulfur, chromium, nitrogen, nickel, titanium, and iron elements. They are titanium-stabilized austenitic stainless steels with good general corrosion resistance. Stainless Steel 321/321H Pipe Fittings also contain small amounts of other elements such as aluminium, cobalt, copper, and tungsten. These elements help improve the overall strength and corrosion resistance of the fittings. The carbon content in Stainless Steel 321/321H Pipe Fittings is typically around 0.08%, while the nickel content is around 9-12%. The chromium content is typically around 17-19%, while the titanium content is around 5 times the carbon content.

Applications:
Stainless Steel 321/321H Pipe Fittings find wide applications in aerospace, chemical and petrochemical processing, petroleum refining, power generation plants, food processing, piping systems, textile equipment, pulp and paper plates, tanks, oil and refinery, flue gas desulfurization systems, pressure vessels, and more.
