Based in Chennai, India, Vinit Stainless is a top producer and supplier of high-end stainless steel goods. The company, which is well-known for its dedication to quality and performance, provides a wide variety of stainless steel sheets, plates, and coils made for demanding industries like manufacturing, automotive, and construction. SMO 254, a high-alloy stainless steel renowned for its remarkable strength, durability, and resistance to corrosion, is one of our specialty products. In demanding industrial, chemical, and marine applications in India and around the world, SMO 254 Sheets and Plates provide exceptional performance and structural integrity.
Super-austenitic stainless steel SMO 254 was created with exceptional corrosion resistance in mind. In addition to nitrogen for strength and stability, its chemical composition normally consists of 4.5% nickel, 6.5% molybdenum, and 25% chromium. Particularly in acidic and chloride-rich environments, this alloy provides remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. Mechanical characteristics include outstanding weldability and ductility, a yield strength of 500 MPa, and a tensile strength of roughly 760 MPa. Because of these characteristics, SMO 254 is a great option for use in demanding and corrosive service environments.

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.
Vinit Stainless commits to delivering the best seamless experience to our valued customers with extensive documentation on top-quality SMO 254 Sheets and Plates. We deliver to our clients, all necessary documents such as the commercial invoice, packing list, fumigation certificate, heat treatment chart, quality assurance plan, and NABL-approved lab test reports, all of which would ensure authenticity as well as superiority in our product offerings. In addition, test certificates, MTC according to EN 10204/3.1b, PMI Test Certificate, 100% radiography test report, and Third Party Inspection Certificate are supplied with our SMO 254 Sheets and Plates, which reveal our customer-oriented approach and a commitment to producing high-quality products.
Industries that require exceptional mechanical strength and corrosion resistance frequently use SMO 254 Sheets and Plates. The material is frequently exposed to acids, chlorides, and other corrosive substances in chemical processing facilities, offshore oil and gas platforms, and marine environments. Because of its great resistance to pitting and cracking, the alloy is also used in heat exchangers, pressure vessels, desalination plants, and food processing equipment. SMO 254 is a preferred material in seawater handling systems because of its dependability in challenging, high-salinity environments, which guarantees longer service life and lower maintenance costs.
