Stainless Steel 304H Flanges
Sankalp Alloys Overseas is one of the premier manufacturers, suppliers, stockists, and exporters of high-quality Stainless Steel 304H Flanges, which are used for a wide range of industrial applications. Our Stainless Steel 304H Flanges are fabricated from premium austenitic stainless steel alloy contents of chromium 18% and nickel 8%, further adding features of higher strength, durability, and resistance against corrosion.
Our Stainless Steel 304H Nippo Flanges find special applications among users in cleanroom and other specialized settings in the medical and pharmaceutical industries. Since we anneal them carefully with rapid cooling from 1500°F to 800°F (-816°C to 427°C), the formation of chromium carbides does not happen, thus retaining the integrity of such flanges for high-purity applications.

Our SS 304H Weld Neck Flanges have improved resistance against corrosive media, such as nitric acid and acetic acid. Hence, these are used primarily in the petroleum refining and petrochemical processing industries. Accordingly, terminations in pipelines and leakage-proof connections formulate the main application of the SS 304H Blind Flanges we offer in high-demanding environments.
Under highly reducing conditions, the SS 304H Threaded Flanges perform easily in sour service. Our Stainless Steel 304H Lap Joint Flanges offer great performance in normal atmospheric conditions with great resistance to natural acids and corrosive media. Our Stainless Steel 304H Ring Type Joint Flanges and SS 304H Orifice Flanges offer outstanding performance in high strength and high-durability applications. These flanges are intended to operate at high-stress or high-pressure environments; thus, cold work will increase hardness along with strength.
