Grade 321 / 321H UNS (S32100, S32109), DIN (1.4541, 1.4878)
Stainless Steel 321/321H Forged Fittings are a type of titanium-stabilized austenitic stainless steel. Their typical chemical makeup includes Chromium (17-19%), Nickel (9-12%), and Titanium (≥5x C), with very low Carbon levels (≤0.08% for 321 and 0.04–0.10% for 321H). These grades are known for their outstanding resistance to intergranular corrosion and impressive strength at high temperatures. They boast mechanical properties like a tensile strength of ≥515 MPa, yield strength of ≥205 MPa, and elongation of ≥40%. The higher carbon content in 321H enhances its creep resistance and strength at elevated temperatures, making these fittings perfect for high-stress, high-temperature applications.

You’ll find Stainless Steel 321/321H Forged Fittings widely utilized in industries that demand excellent corrosion resistance and high-temperature performance. This includes sectors like chemical processing, oil and gas, power generation, heat exchangers, and refineries. Their stability against carbide precipitation makes them ideal for applications that involve continuous and intermittent heating within the 800–1500°F (427–816°C) range. The 321H variant, with its higher carbon content, is particularly favored in high-pressure, high-heat systems such as boilers and superheaters. These fittings are also essential in aerospace engine parts, exhaust manifolds, and furnace components, where strength and resistance to oxidation are crucial for long-lasting performance.
