Harsh Flanges stands out as a reputable manufacturer and supplier of SMO 254 Flanges, located in Mumbai, India. They specialize in high-performance alloy flanges that are designed to offer exceptional corrosion resistance and strength, even in the toughest environments. Renowned for their ability to resist pitting, crevice corrosion, and chloride stress corrosion cracking, these flanges are perfect for demanding sectors like chemical processing, offshore oil and gas, desalination, and marine applications. With a commitment to quality, precision, and adherence to global standards, Harsh Flanges guarantees that every SMO 254 flange meets international benchmarks, ensuring reliable performance and lasting durability across various industries.
SMO 254 Flanges are crafted from a high-alloy austenitic stainless steel that includes about 20% chromium, 18% nickel, 6% molybdenum, along with some nitrogen and copper. This unique blend provides the alloy with remarkable resistance to pitting and corrosion caused by chlorides. With a tensile strength of around 650 MPa and a yield strength of 300 MPa, these flanges maintain high ductility and impact toughness, even in freezing temperatures. They also boast excellent weldability and formability, making them ideal for harsh environments involving seawater, aggressive chemicals, and high temperatures where standard stainless steels might not hold up.
