Stainless Steel 304 Pipe Fittings
Sankalp Alloys Overseas is one of the professional manufacturers, suppliers, stockists, and exporters of high-quality Stainless Steel 304 pipe fittings. Stainless Steel 304 represents one of the most popular stainless steel grades. It is an alloy steel with a composition that includes both nickel and chromium—the primary non-iron elements. This austenitic stainless steel alloy has very good resistance to corrosion, high-temperature strength, and general durability.
Stainless Steel 304 pipe fittings include elbows, tees, crosses, and stub ends that bear up in many environments. Due to the high hot strength, Stainless Steel 304 elbows show a tendency for stress-corrosion cracking; on the other hand, Stainless Steel 304 tees show very good resistance to atmospheric corrosion, as well as moderately oxidizing and reducing conditions. It is also possible to weld stainless steel 304 crosses with minimal loss of their corrosion resistance. On the other hand, for optimal conditions so that maximal corrosion resistance in stainless steel 304 end caps can be attained, it has to be followed by final annealing above 1070°C, with rapid cooling.
These pipe fittings exhibit very good resistance to corrosion in a variety of chemicals, especially acid chloride environments, such as those found in pulp and paper mills. On the other hand, higher chromium, molybdenum, and nickel content in Stainless Steel 304 end caps enhances resistance to chloride pitting and general corrosion. Though non-magnetic in the annealed condition, Stainless Steel 304 fitting may become slightly magnetic due to welding.
Sankalp Alloys Overseas is engaged in manufacturing fittings using Stainless Steel 304 grade and allied metal alloys to international quality norms. We offer customized specifications and standards according to client needs. Our fitting products include all types of fittings, running from a wide spectrum: long and short radius elbows, reducing elbows, 45-degree elbows, tees, fabricated tees, reducers—the eccentric or concentric type—stubs, crosses, reducing crosses, return bends (180-degree LR and SR), pipe bends, couplings (full and half couplings), pipe nipples, plate cut rings, end caps, plate circles.
We also offer ASTM A403 WP304 fittings in our range of Stainless Steel 304 pipe fittings at very competitive prices. The fittings have good resistance to corrosion in a wide range of different environments, making them particularly suitable for cryogenic and high-temperature applications as well as for use in the dairy, food, and pharmaceutical industries. Heat treatment: Heat to 1010-1120°C and then rapidly cool in air or water. Annealing: Soak at 816°C 1500°F and then water quench to give optimal properties.
