Located in Mumbai, India, Harsh Metalloys is a well-known producer and supplier of premium stainless steel 310S flanges that are made to withstand the demanding conditions of corrosive and high-temperature industrial settings. Our SS 310S flanges are made with premium materials and cutting-edge processes to guarantee exceptional durability, strength, and resistance to corrosion. These flanges are renowned for their accuracy and dependability, meet international quality standards, and are appropriate for crucial applications across a range of industries. Harsh Metalloys remains a reliable supplier of stainless steel flange solutions in India and overseas thanks to its dedication to innovation, quality control, and client satisfaction.
The iron that makes up stainless steel 310S flanges has 24–26% chromium, 19–22% nickel, and a low carbon content (≤0.08%), which improves weldability and reduces carbide precipitation. At temperatures as high as 1100°C, these flanges provide exceptional resistance to oxidation and scaling. Tensile strength of about 515 MPa, yield strength of 205 MPa, and elongation of about 40% are among the mechanical characteristics. SS 310S flanges are perfect for use in high-temperature applications that demand durability and corrosion resistance because they maintain their high strength and structural integrity under extreme heat conditions.
