Nial Sheets and Plates is a well-respected manufacturer and supplier of Stainless Steel 348 Sheets and Plates based in Houston, USA. They provide top-notch materials specifically designed for high-temperature and corrosive environments. Stainless Steel 348 is a stabilized austenitic stainless steel alloy that incorporates niobium (also known as columbium) to prevent carbide precipitation during welding and exposure to high temperatures. Nial produces these sheets and plates to comply with strict international standards, making them perfect for industries like aerospace, chemical processing, power generation, and nuclear energy. Renowned for its excellent weldability, oxidation resistance, and strength, Stainless Steel 348 ensures long-lasting performance even in the most extreme conditions.
The composition of Stainless Steel 348 Sheets and Plates primarily includes chromium (17–19%), nickel (9–13%), and columbium/niobium for stabilization, along with small amounts of manganese, silicon, and carbon. While this alloy is similar to 347, it offers improved resistance to high-temperature creep. It boasts mechanical properties such as tensile strength ranging from 515–750 MPa and yield strength around 205 MPa, along with good elongation and toughness. 348 maintains its corrosion resistance and mechanical integrity even in high-temperature applications, making it suitable for continuous exposure to elevated heat without the risk of intergranular corrosion.
