321 / 321H Stainless Steel Flanges

We, Saffron Steel & Engineering., are manufacturing and supplying a wide range of Flanges in different grades. SS 321/321H Flanges are one of the types of Flanges available in our inventory. Every kind of Flange has its unique qualities and characteristics. By considering all requirements of industrial and to contribute to their growth, we are producing all types of Flanges with various specifications.

Alloy 321 is Austenitic Titanium with Chromium-Nickel Stainless Steel. This grade specially develops to provide Intergranular corrosion resistance. Alloy 321 is suitable for applications where welding under high temperatures is required. This Alloy 321 has 0.08% of Carbon, 0.75% of Silicon, 0.10% of Nitrogen, and 2% Manganese. Alloy 321H is a higher Carbon version of 321 alloys which offers a variety of benefits. Alloy 321H provides good low-temperature toughness, excellent resistance to oxidation, very ductile, and forms quickly. All these features and qualities are beneficial to manufacture Flanges. We, Saffron Steel & Engineering., are producing the highest quality SS 321/321H Flanges in a variety of length, standard, dimensions, wall thickness with excellent surface finishing.
