They specialize in high-performance, heat-resistant stainless steel designed for tough industrial settings. With a reputation for sourcing top-notch materials that comply with international standards, Yousef Steel caters to a diverse array of industries, including petrochemical, power generation, cement, and heat treatment. Their 253MA sheets and plates are perfect for high-temperature structural applications, offering outstanding oxidation resistance, mechanical strength, and long-lasting stability. With reliable service, quick delivery, and expert assistance, Yousef Steel has become a go-to partner for heat-resistant steel products throughout Saudi Arabia and the Middle East.
**253MA (UNS S30815) Sheets and Plates** are crafted from a high-temperature austenitic stainless steel alloy that contains about 21% chromium, 11% nickel, 1.7% silicon, along with small amounts of rare earth metals. These components boost oxidation resistance and enhance strength at high temperatures. 253MA boasts impressive mechanical properties, featuring a tensile strength of roughly 600–800 MPa and a yield strength of 310 MPa. It can withstand oxidation up to 1150°C and maintains good structural stability during thermal cycling. Despite its heat-resistant qualities, 253MA is still weldable and can be easily fabricated using standard techniques.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
253MA (UNS S30815) plates and sheets have widespread application at elevated temperatures due to their better oxidation and creep resistance. They are used in furnace components, heat exchangers, kiln linings, boiler parts, and incinerators where extreme heat and thermal cycling occur. The high strength and corrosion resistance of the alloy render it well suited for petrochemical, power generation, cement, and steel industries. In addition, it is applied in industrial processing plant exhaust systems, conveyors, and burners. With better mechanical properties and weldability, 253MA is the best for structural parts subject to oxidation, carburization, and thermal fatigue in severe environments.
