Stainless Steel 304H Flanges Supplier. ASTM A182 SS 304H Flanges Manufacturer in India.

Stainless Steel 304H Flanges Supplier, Manufacturer

Unichem Steel & Alloy Pvt. Ltd. is one of the specialized production houses & dealers of SS 304H Flanges, which is a steel alloy with a minimum of 10.5 % chromium content by mass. Our Stainless Steel 304H Slip On Flanges is notable for their corrosion resistance, and it is widely used for food handling and cutlery among many other applications. These Stainless Steel 304H Threaded Flanges do not readily corrode, rust or stain with water as ordinary steel does. However, our Stainless Steel 304H Weld Neck Flanges are not fully stained–proof in low–oxygen, high–salinity, or poor air-circulation environments. These Stainless Steel 304H Blind Flanges are used where both the properties of steel and corrosion resistance are required. Our Stainless Steel UNS S30409 Socket Weld Flanges differ from carbon steel by the amount of chromium present. These unprotected Stainless Steel 304H Lap Joint Flanges rust readily when exposed to air and moisture. Since iron oxide has a lower density than these Stainless Steel 304H Ring Joint Type Flanges, the film expands and tends to flake and fall away. In comparison, our Stainless Steel 304H Spectacle Blind Flanges contain sufficient chromium to undergo passivation, forming an inert film of chromium oxide on the surface. The layer prevents further corrosion by blocking oxygen diffusion to the surface of these Stainless Steel 304H Spacer Flanges and stops corrosion from spreading into the bulk of the metal.
