Harsh Flanges is a reputable manufacturer and supplier of Stainless Steel 348 Flanges, proudly based in Mumbai, India. We’re known for providing high-performance flange solutions that stand up to the toughest industrial environments. Thanks to our advanced manufacturing capabilities and rigorous quality control, we deliver SS 348 flanges that boast impressive resistance to corrosion, stability at high temperatures, and a long lifespan. Our flanges are crafted to meet international standards, serving a variety of industries including petrochemical, aerospace, power generation, and chemical processing. At Harsh Flanges, we prioritize precision engineering, reliability, and customer satisfaction, making us the go-to partner for durable stainless steel flange solutions.
Stainless Steel 348 Flanges are primarily made up of iron, chromium (17–20%), nickel (8–11%), and columbium (niobium) to enhance stabilization. They exhibit remarkable mechanical properties, with a tensile strength of about 550 MPa, yield strength around 240 MPa, and good elongation of up to 35%. These flanges are particularly resistant to intergranular corrosion and oxidation, especially when exposed to high temperatures. SS 348 flanges maintain their mechanical integrity even under thermal cycling, making them perfect for high-stress, high-temperature applications where stability and durability are crucial.
