ASTM A182 Stainles Steel F304 is an austenitic Stainless Steel made with the combination of chromium and Nickel. SS 304 is the most versatile and commonly used material to manufacture Flanges. This SS grade 304 exhibits excellent corrosion resistance and can be machined easily in any form using conventional manufacturing methods. The sufficient quantity of Nickel in it makes it able to resist moderately aggressive organic acids and to perform consistently in most corrosive environments. ASTM A182 SS F304 Blind Flanges have high weldability and can be welded using all conventional welding methods. These Flanges can be used between a considerable temperature range that is 800-1580°F.
