SMO 254 is a super austenitic stainless steel alloy that boasts around 20% chromium, 18% nickel, 6% molybdenum, and 0.2% nitrogen, which gives it remarkable resistance to corrosion. The addition of small amounts of manganese, copper, and silicon enhances its strength and durability even further. In terms of mechanical properties, SMO 254 sheets and plates showcase high tensile and yield strength, good elongation, and exceptional resistance to pitting and stress corrosion cracking. This alloy maintains its structural integrity even in harsh chemical environments and at elevated temperatures, making it a reliable choice for critical industrial applications.

SMO 254 hot rolled plates have high strength and resistance to corrosion, and therefore, can be used for heavy-duty applications. The material is usually in a thickness range of 3mm to 50mm with width up to 2000 mm. It also comes in hot-rolled finish for strength and durability with the capability of sustaining high temperature and aggressive environment.
SMO 254 Cold Rolled Sheets provide a bright surface finish and excellent dimensional accuracy, with good corrosion resistance. These sheets are available in thickness from 0.5 mm up to 3 mm and widths up to 1250 mm. The strength of these sheets is improved by cold rolling, making them ideal for precision applications.
SMO 254 Chequered Plates offer an embossed pattern for increased slip resistance and longevity. Thickness options range from 3 mm to 12 mm, with a maximum width of 1500 mm. They are used as flooring in most industrial applications, offering great corrosion resistance.
SMO 254 Perforated Sheets come in different perforation patterns depending on the design and functional requirements of the application. They are offered in thickness ranges from 1mm to 6mm and width up to 1200 mm. Due to their high resistance to corrosion, they are used both for decorative as well as industrial applications.
SMO 254 Shim sheets are used with a spacing or aligned application for variety of usages. Generally made available with widths up to 1000mm and a standard thickness between 0.1 mm and 1mm these shim sheets promise excellent corrosion resistivity under stringent conditions, performing well even during long exposure.
SMO 254 Polished Plates have high-quality reflective surfaces and are aesthetically pleasing along with corrosion resistant. They have a thickness from 2mm to 25mm and can be up to 1500mm in width. The architectural and decorative usage is possible by the polished surface.
