ASTM B462 UNS N08020 Flange, Carpenter 20 Pipe Flange, Alloy 20Cb3® Blind Flanges Manufacturer in India
Alloy 20 Flanges is widely used in springs, fasteners, washers, zippers, clips, clamps, computer parts, contacts, stampings for a variety of parts, pins and more. Alloy 20Cb3® Threaded Flanges is a commonly available austenitic steel with good corrosion resistance and high carbon content to allow cold workability in a wide range of tempers. It is a modification in which the chromium and nickel content is reduced to increase the work hardening range. Carpenter 20 Pipe Flange is suitable for all types of welding and shows good ductility in cold working. The chemistry of this steel enables it to be cold worked with the ideal combination of mechanical properties desired for specific applications.
We as a Metalfed Engineering is a well-known manufacturer, exporter, supplier and trader of Alloy 20 Lap Joint Flanges, which is a popular austenitic chromium-nickel steel known for its resistance to corrosion. It is not hardenable by heat treatment. WNR 2.4660 Weld Neck Flanges is an austenitic chromium-nickel steel that offers high strength and good ductility when cold worked. Strength and good corrosion resistance in slightly corrosive environments at room temperature. ASTM B46 UNS N08020 Threaded Reducing Flanges is non-magnetic when annealed but becomes magnetic after cold working. It has the highest tensile strength among forged austenitic stainless steels.
