Harsh Metalloys, a top manufacturer and supplier based in Mumbai, India, specializes in high-quality Stainless Steel 410HT Pipes that boast remarkable mechanical strength, hardness, and thermal stability. The SS 410HT is a high-temperature version of the standard 410 martensitic stainless steel, uniquely heat-treated to boost its performance in high-stress and elevated temperature settings. These pipes are crafted in line with ASTM A312 and other international standards, ensuring they offer excellent dimensional accuracy, durability, and resistance to corrosion. SS 410HT pipes are perfect for use in petrochemical, power generation, oil and gas, and heat exchanger systems where high strength and oxidation resistance are crucial.
Stainless Steel 410HT Pipes mainly consist of 11.5–13.5% Chromium and up to 0.15% Carbon, along with Manganese, Silicon, and trace elements. The HT (heat-treated) variant goes through a specialized quenching and tempering process to enhance its hardness, tensile strength (up to 750 MPa), and wear resistance. These pipes show improved oxidation resistance up to 650°C, good creep strength, and moderate corrosion resistance. They can be welded with the right precautions and are not hardenable through cold working. SS 410HT pipes are well-suited for high-temperature service and dynamic loading applications.
