Harsh Metalloys is a well-known manufacturer and supplier of Stainless Steel 253MA Pipes, located in Mumbai, India. The 253MA (UNS S30815) is a high-temperature austenitic stainless steel that’s specifically engineered to provide outstanding oxidation resistance, impressive strength, and long-lasting durability in high-temperature settings. Harsh Metalloys offers 253MA pipes in both seamless and welded varieties, available in a range of sizes and specifications that meet ASTM A312 and other international standards. These pipes are widely utilized in industrial furnaces, petrochemical facilities, heat exchangers, and power generation systems, where resistance to thermal stress and chemical corrosion is crucial for dependable performance.
Stainless Steel 253MA Pipes mainly consist of 20–22% chromium and 10–12% nickel, with carefully controlled amounts of cerium (~0.05%) and nitrogen (~0.15%) that boost oxidation resistance and creep strength. These pipes have a tensile strength of about 600 MPa and a yield strength of 310 MPa, making them capable of operating at temperatures as high as 1150°C (2100°F). The 253MA offers excellent protection against carburization, sulfur attack, and thermal fatigue, while also ensuring good weldability and formability. It’s perfect for environments that require reliable mechanical performance even under prolonged exposure to extreme heat and corrosive conditions.
