Stainless Steel 310 Flanges Manufacturer in India
SS 310 stainless steel is a premium grade of austenitic stainless steel alloy, with a composition of high chrome and high nickel that is specifically engineered to provide excellent performance in an environment with extremely high temperatures and oxidation. The chromium content is great with regard to oxidation and corrosion resistance, whereas the nickel content makes it strong and resistant to high temperatures. SS 310 Flanges have become very popular in piping systems that require high thermal resistance, mechanical strength, corrosion resistance, and a long life cycle. These flanges are used in high-pressure, high-temperature, and chemically hostile environments and provide good structural integrity and leak-free connections in chemical processing, petrochemical plants, refineries, power generation units, furnaces, heat treatment plants, exhaust environments, offshore, and other extreme environments of the industrial environment.

What Are SS 310 Flanges?
The SS 310 flanges are made in line with ASTM A182 F310 and are made out of forged and rolled stainless steel, and are used in high-performance and high-temperature piping systems. It is a grade that has a high composition of chromium and nickel that renders it very resistant to oxidation, scaling, and corrosion in a continuous service operation at high temperature. The SS 310 flanges are designed in a special way to suit systems that are subjected to excessive pressure, heat, and difficult industrial media. They find application in chemical facilities, refineries, petrochemical plants, furnaces, heat exchangers, power facilities, thermal processing, exhaust, offshore facilities, and other high-performance applications that require thermal stability, corrosion resistance, and a long service life.
