Hassan Sheets and Plates is a reputable manufacturer and supplier located in Riyadh, Saudi Arabia, providing a top-notch range of stainless steel products, including Stainless Steel 348 Sheets and Plates. Renowned for their precision, quality, and commitment to international standards, Hassan caters to essential industries like aerospace, petrochemical, power generation, and thermal processing. Stainless Steel 348 is an austenitic stainless steel that’s stabilized with niobium, known for its remarkable resistance to intergranular corrosion and outstanding performance in high-temperature settings. Hassan offers customized sheet and plate solutions tailored to meet the demanding needs of modern industrial applications, both locally and internationally.
The composition of Stainless Steel 348 Sheets and Plates includes iron, 17–20% chromium, 8–11% nickel, and niobium (columbium) for stabilization. This blend boosts resistance to intergranular corrosion, particularly after welding, while also maintaining mechanical strength at higher temperatures. The alloy boasts a tensile strength ranging from 515 to 750 MPa, a yield strength of about 205 to 350 MPa, and an elongation of roughly 35 to 40%. It also retains excellent toughness, weldability, and oxidation resistance, making it a dependable choice for demanding applications that involve heat and stress.
