Harshita Stainless, located in Delhi, India, is a reputable manufacturer and supplier of high-quality Stainless Steel 347 Tubing, designed specifically for high-temperature and corrosive environments. SS 347 is a niobium-stabilized austenitic stainless steel that excels in resisting intergranular corrosion and performs exceptionally well during welding and thermal cycling. Harshita Stainless offers tubing in a variety of sizes, thicknesses, and finishes, all customized to meet both national and international standards. With a strong commitment to quality, customization, and prompt delivery, the company caters to industries such as chemical processing, power generation, aerospace, and oil & gas, both in India and around the globe.
Stainless Steel 347 tubing consists of 17–20% chromium, 9–13% nickel, and niobium (columbium), which stabilizes the alloy and helps prevent carbide precipitation during welding. It boasts impressive mechanical properties, with a tensile strength of about 515 MPa, yield strength near 205 MPa, and Brinell hardness between 150–200 HB. SS 347 maintains its structural integrity at elevated temperatures up to 870°C and offers excellent resistance to creep and stress rupture. The tubing is non-magnetic in its annealed state and showcases outstanding weldability, oxidation resistance, and protection against intergranular corrosion.
