The ASTM A403 covers Austenitic Stainless Steel Pipe Fittings used in engineering industry, energy conversion plants, etc.

ASTM A403 Pipe Fittings

ASTM A403 Pipe Fittings

ASTM A403 is a standard specification for steel pipe fittings. These pipe fittings have very good ductility, good weldability. These pipe fittings are manufactured in both seamless and welded forms such as elbow, tee, reducers, cap, bend, stub-end, collar, cross, etc. Siddhagiri Metals and Tubes is well known global supplier of 254 Smo Pipe Fittings, 304 Stainless Steel Pipe Fittings, 304h Stainless Steel Pipe Fittings, 309 Stainless Steel Pipe Fittings, 310 Stainless Steel Pipe Fittings, 316h Stainless Steel Pipe Fittings, 316l Stainless Steel Pipe Fittings, 316ti Stainless Steel Pipe Fittings, 317l Stainless Steel Pipe Fittings, 321 Stainless Steel Pipe Fittings, 321h Stainless Steel Pipe Fittings, 330 Stainless Steel Pipe Fittings, 347 Stainless Steel Pipe Fittings, 347h Stainless Steel Pipe Fittings, 904l Stainless Steel Pipe Fittings, in best quality.

Stainless Steel Pipe Fittings

Stainless Steel Pipe Fittings is a nickel-chromium alloy bar that contains supplemental amounts of columbium, iron, molybdenum, aluminum, and titanium. Stainless Steel Pipe Fittings have high strength properties, heat treatable, good corrosion resistance, formability and weldability. Stainless Steel Pipe Fittings has excellent cryogenic and heat ranges. Common uses of Stainless Steel include deployment in gas turbines, subservice safety valves, aircraft engines, thrust reversers, and industrial fasteners.

Scope And Manufacturing

ASTM A403 specification covers stainless steel pipe fitting components used in pressure systems. These pipe fittings are manufactured in seamless and welded type. The material for fittings consist of seamless or welded piping products. Shaping operations is performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining, or by a combination of two or more of these operations. The welding of pipe is done through shielded metal arc welding (SMAW), gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW). In GMAW process an inert gas such as argon, helium, carbon dioxide or a mixture of them are used to prevent atmospheric contamination of the weld. The shielding gas is allowed to flow through the weld gun. The electrode used here is, in a wire form, fed continuously at a fixed rate. The wire is consumed during the process and thereby provides filler metal.
