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, KIRAN PIPE FITTING & MANUFACTURING COMPANY., are producing the highest quality SS 321/321H Flanges in a variety of length, standard, dimensions, wall thickness with excellent surface finishing.
Our SS 321/321H Flanges has properties like corrosion resistance ability, durability, corrode free, resistance to oxidation, toughness, and high weldability property. These beneficial Flanges are perfectly suitable in various industries such as the petrochemical industry, pulp, and paper industry, chemical industry, pharmaceutical industry, aerospace industry, food processing industry, oil and gas industry, and power plant industry.
