Aditya Stainless stands out as a top manufacturer and supplier of Stainless Steel 348H Sheets and Plates, proudly based in Kolkata, India. Crafted for high-temperature and high-pressure settings, these sheets and plates are made from a columbium-stabilized austenitic stainless steel alloy, ensuring remarkable resistance to intergranular corrosion and stress rupture. Offered in a variety of thicknesses, widths, and finishes, our SS 348H sheets and plates meet international standards like ASTM A240 and ASME SA240. Renowned for their structural integrity and precise dimensions, these products are perfect for critical applications in sectors such as power generation, chemical processing, and heat exchangers.
Stainless Steel 348H Sheets and Plates mainly consist of chromium (17–19%), nickel (9–13%), and columbium (niobium) along with tantalum for stabilization, featuring a higher carbon content to enhance high-temperature strength. These plates boast a tensile strength of about 585 MPa, a yield strength of 240 MPa, and an elongation of roughly 35%. The alloy excels in creep resistance, oxidation resistance, and structural stability at elevated temperatures, making it ideal for applications that involve continuous thermal exposure and welded construction.
