FAISAL Steel, based in Muscat, Oman, stands out as a top-notch manufacturer and supplier of high-quality 253MA UNS S30815 sheets and plates. They cater to industries that require robust, heat-resistant stainless steel. Known for their commitment to quality, precision, and customer satisfaction, FAISAL Steel produces materials that adhere to strict international standards. Thanks to their advanced manufacturing techniques and rigorous quality control, they guarantee exceptional strength, thermal stability, and corrosion resistance in every product. They serve various sectors, including power generation, petrochemicals, furnace manufacturing, and heat treatment, providing durable and reliable 253MA steel solutions designed for extreme temperatures and demanding industrial applications.
253MA (UNS S30815) plates and sheets are high-temperature stainless steel alloys with a controlled composition of Cr (20-22%), Ni (10-12%), Si (1.4-2.0%), N (0.14-0.2%), and Ce (0.03-0.08%), which improves oxidation and creep resistance. They have outstanding mechanical properties, such as yield strength of 310 MPa, tensile strength of 650 MPa, and elongation of 40%, making them long-lasting in harsh environments. The superior weldability, combined with the high melting point (~1420°C), 253MA excels as suitable for furnace componentry, heat exchangers, and various high-temperature applications that call for optimum performance.
