A 321 stainless steel forged flange typically contains elements such as chromium, nickel, manganese, silicon, phosphorus, and sulfur. In particular, it has a higher chromium content (18–20%) and nickel content (9–12%) than 304-grade stainless steel. It also contains other elements like molybdenum and titanium which give the alloy its corrosion-resistant properties.

SS 321 forged flange is an excellent choice for harsh-environment applications such as in marine environments, high-pressure atmospheres, and where sulfur-bearing compounds are present. The alloy boasts a number of beneficial properties including good corrosion resistance, heat resistance up to 1500°F (816°C), and excellent toughness at cryogenic temperatures. It also has higher strength than 304-grade stainless steel and its low carbon content helps to reduce carbide precipitation during welding. Additionally, this type of flange is weldable using both GTAW and GMAW with appropriate filler materials.
