Harshita Stainless is a well-respected manufacturer and supplier based in Delhi, India, specializing in top-notch Stainless Steel 316H Tubing designed for high-temperature and high-pressure applications. This grade stands out due to its higher carbon content compared to standard 316, which enhances its strength and creep resistance, making it perfect for tough industrial settings. Harshita Stainless prides itself on delivering tubing solutions with meticulous craftsmanship, strict adherence to international quality standards, and a strong focus on customer satisfaction. With an extensive distribution network and a dedication to quality, the company has established itself as a trusted partner for industries like petrochemical, power generation, oil & gas, and heat exchanger manufacturing both in India and internationally.
Stainless Steel 316H is a high-carbon version of 316, featuring 0.04–0.10% carbon, 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. The added carbon boosts its strength at high temperatures, making it suitable for elevated service conditions. Typically, SS 316H tubing boasts a tensile strength of 515 MPa and a yield strength of 205 MPa, along with impressive ductility and toughness. It maintains its structural integrity under thermal stress and offers excellent resistance to oxidation and general corrosion, especially in harsh and high-temperature industrial environments.
