Alloy 20 Flange

Alloy 20 Flanges (UNS N08020) is an austenitic stainless steel grade having the composition of iron, nickel, and chromium base alloy flanges with a moderate amount of molybdenum and copper that provides resistance to hostile environments. Those are pitting, crevice and stress corrosion cracking. This grade is stabilized with columbium to decrease the carbide precipitation or sensitization while welding.

These flanges appear to fall between both stainless steel grade and nickel category at it has properties of both grades. These are developed to meet maximum corrosion resistance to acidic environments and display superior resistance to SSC in the boiling sulfuric acids. it has also resistance to general corrosion caused by sulfuric acids and also to chloride-induced stress corrosion cracking. These flanges have great mechanical properties in the nominal temperatures to hoisted temperatures up to 500 deg C. these flanges are readily formable with standard fabrication and welding operations.

Alloy 20Cb-3® Weld Neck Flange, DIN 2.4660 Lap Joint Flange, Alloy 2.4660 Ring Type Joint Flange Exporter, UNS N08020 Socket Weld Flange, Alloy 20 Orifice Flange, 20 Alloy Industrial Flanges Manufacturer in India.

These are made by us in both hot and cold working operations. The hot working process is recommended to achieve the desired resistivity, however, it becomes non-magnetic in nature after the annealing process. The cold working operations are performed to attain maximum mechanical properties while turning structure to magnetic in nature. The industrial refining process is performed to refine its structure, dimensional accuracy, and surface finish.

The errors are being checked in the testing session that assures its quality. The tests are IGC test, hardness test, mechanical test, tensile test, radiography test, destructive test, and other tests demanded by customers.
