Khush Sheets and Plates stands out as a top-notch manufacturer and supplier of Stainless Steel 347H Angles, proudly based in Delhi, India. This high-carbon, niobium-stabilized austenitic stainless steel is crafted for superior strength and impressive creep resistance, especially at elevated temperatures. Our 347H angles are made in line with ASTM A276 and ASTM A240 standards, guaranteeing exceptional mechanical integrity, weldability, and corrosion resistance. We cater to a diverse array of industries, including petrochemical, thermal power, oil & gas, and aerospace, where durability, oxidation resistance, and high-temperature stability are absolutely essential.
Stainless Steel 347H is composed of 17–20% chromium, 9–13% nickel, and a higher carbon content (0.04–0.10%), along with niobium (columbium) for stabilization. This unique alloy offers enhanced creep resistance, high-temperature strength, and remarkable resistance to intergranular corrosion. Its mechanical properties boast a tensile strength of 515–750 MPa, a yield strength of around 205 MPa, and an elongation of about 40%. SS 347H maintains its mechanical stability at temperatures exceeding 500°C, making it perfect for high-stress, thermal applications. At Khush Sheets and Plates, we ensure that every angle meets rigorous quality standards for toughness, dimensional accuracy, and corrosion resistance.
