Harshita Stainless has built a solid reputation as a reliable manufacturer and supplier of Stainless Steel 309H Pipe Fittings, providing top-notch piping solutions to clients in both Dubai and India. Located in Delhi, India, the company focuses on crafting high-temperature and corrosion-resistant stainless steel products designed for demanding industrial applications. The Stainless Steel 309H Pipe Fittings are particularly noted for their elevated carbon content, which boosts their strength and stability even at high temperatures. Thanks to their state-of-the-art manufacturing facilities and rigorous quality control measures, Harshita Stainless ensures that their pipe fittings meet international standards for performance, durability, and precision.
These fittings are primarily made up of iron, along with 22–24% chromium, 12–15% nickel, and a higher carbon content compared to standard 309. This unique blend enhances their tensile strength (around 550 MPa) and yield strength (approximately 220 MPa), making them perfect for high-temperature and high-pressure applications. They also boast impressive resistance to oxidation, thermal fatigue, and creep, maintaining their structural integrity at temperatures reaching up to 1000°C.
