Adinox Overseas is a globally recognized name in the supply and export of premium quality 253 MA [S30815] Sheets, also known by the UNS number S31254. These high-alloy austenitic stainless steel sheets are engineered to deliver excellent performance in extremely aggressive environments, offering superior resistance to pitting, crevice corrosion, and stress corrosion cracking. Manufactured in accordance with the ASTM A240 standard, our 253 MA [S30815] Sheets are widely used in a broad range of industrial applications, especially where high chloride environments or acidic media are involved.
The unique composition of SMO 254 includes high levels of molybdenum (up to 6%) and nitrogen, which significantly enhances its corrosion resistance beyond that of standard austenitic grades such as 316L or 317L. This makes it an ideal choice for applications in seawater handling, offshore oil and gas platforms, heat exchangers, flue-gas cleaning, and pulp & paper industries. Due to its high PREN (Pitting Resistance Equivalent Number) of more than 42.5, SMO 254 stainless steel sheets outperform many conventional alloys in demanding conditions.
Our 253 MA [S30815] Sheets are available in various thicknesses, widths, and lengths to meet diverse project requirements. We offer mill finish, No.4 finish, 2B, and custom surface finishes to suit different operational and aesthetic needs. All sheets supplied by Adinox Overseas undergo rigorous quality control and are provided with Mill Test Certificates, ensuring full traceability and compliance with international standards.
Adinox Overseas supplies 253 MA Stainless Steel Sheets in various thicknesses, widths, and surface finishes as per customer requirements. These sheets are compliant with ASTM A240 and ASME SA240 specifications, ensuring quality consistency and dimensional accuracy. We also offer custom-cut lengths and value-added services like shearing, polishing, and edge preparation to cater to specific industrial needs.
