Harsh Metalloys stands out as a top manufacturer and supplier of Stainless Steel 330 pipes, proudly based in Mumbai, India. We specialize in delivering high-performance piping solutions that are designed to withstand extreme heat and corrosive environments. Our SS 330 pipes are crafted from top-notch raw materials and cutting-edge technology, ensuring they meet the toughest industrial standards. Renowned for their exceptional strength, durability, and heat resistance, our products are trusted by various industries, including heat treatment, petrochemical, power generation, and metallurgy. With a strong commitment to quality assurance, customer satisfaction, and timely delivery, Harsh Metalloys has earned a solid reputation both in India and on the global stage for stainless steel excellence.
Our Stainless Steel 330 pipes are made from a high-temperature resistant austenitic alloy, featuring around 35–37% nickel, 17–20% chromium, and silicon to boost oxidation and carburization resistance. These pipes boast impressive mechanical properties, with a tensile strength ranging from 600–750 MPa and a yield strength of about 300 MPa. They maintain their structural integrity at temperatures over 1100°C and show remarkable resistance to thermal shock. Thanks to their robust chemical composition, they are built to last even in the harshest operating conditions, making them ideal for long-term use in high-temperature industrial settings.
