Harsh Flanges is your go-to manufacturer and supplier of Stainless Steel 348H Flanges, proudly based in Mumbai, India. We specialize in providing high-temperature and corrosion-resistant flange solutions tailored to meet the needs of various industries. Our flanges are crafted using cutting-edge manufacturing techniques and comply with international quality standards, ensuring they deliver long-lasting durability and top-notch performance. Designed specifically for high-temperature applications, Stainless Steel 348H flanges are perfect for critical industrial uses. At Harsh Flanges, we’re dedicated to offering precision, strength, and reliability to clients in the chemical, petrochemical, power, and aerospace sectors.
These Stainless Steel 348H Flanges are made up of iron, chromium (17–20%), nickel (8–11%), columbium (niobium), and a higher carbon content (0.04–0.10%) compared to SS 348. This increased carbon content enhances creep strength and performance at elevated temperatures. With a tensile strength of around 585 MPa, a yield strength of about 240 MPa, and an elongation of roughly 35%, these flanges are built to last. They excel in resisting intergranular corrosion, oxidation, and high thermal stress, making them ideal for demanding applications where mechanical integrity at high temperatures is crucial.
