SS400 Steel Flange

SS400 Steel Flange

We are leading JIS G3101 SS400 Weld Neck Flange and SS400 Mild Steel Blind Flanges Manufacturer in India

The SS400 is a structural grade that is hot rolled in the form of flanges to be used in different applications. The SS400 Steel Flange is designed with a chemical composition of ferrous, silicon, copper, sulfur, and phosphorous. These flanges have moderate corrosion resistance properties and have the capacity to carry heavy weights in the system. The Ss400 Flange is designed with superior mechanical properties. These flanges have a tensile strength between 400 to 510mpa with a minimum yield strength of 245mpa. The Jis 10k SS400 Flange can be elongated by 17% and have a notch impact of 27J at 20 degrees C.

Purchase SS400 flange and JIS G3101 SS400 Socket Weld Flange at lowest price directly from Supplier

The SS400 SORF Flange is a common flange in the industry that is slid on the pipe and welded in place using one or more fillet welds. The cost-effective flanges are generally seen in low-pressure and temperature applications. A JIS G3101 SS400 Socket Weld Flange is seen in pipes of smaller sizes that transmit high-pressure fluids. The flanges are attached by inserting the pipe into the socket end, followed by applying a fillet weld around the top of the flange. The KS SS400 Plate Flange is a versatile flange that is flat and circular, allowing it to be easily bolted to the subsequent pipe module. They are usually bolted together with the help of a gasket and have a serrated finish on the interior of the module. The Carbon Steel SS400 Flanges are designed to contain a higher content of carbon, giving them enhanced strength. These flanges are prone to corrosive media if not properly cared for. A Mild Steel SS400 Flange usually has a carbon content between 0.05% to 0.25% by weight. These flanges are very ductile and can be easily carburized. Apart from this, the cost-effective modules can be easily welded in place and are recyclable.
