SMO 254 sheet, plate, and coil are premium-grade austenitic stainless steel products known for their outstanding corrosion resistance and mechanical strength. These materials are well-suited for environments exposed to chlorides, acidic compounds, and seawater. Composed of high levels of nickel, chromium, molybdenum, copper, and nitrogen, it provides excellent protection against localized corrosion, including pitting and crevice attack. Preston Pipes & Alloys supplies these products, with exacting chemical composition and physical properties that align with international standards. With impressive tensile and yield strength, combined with good ductility, these materials are ideal for high-demand applications.
These components are highly appreciated for their structural integrity, accurate dimensions and refined surface texture. It can be used for any kind of heavy-duty applications due to its capacity to withstand high stress and retain its shape under load. Even in harsh conditions, the products long lifespan is ensured by the robust design and inherent anti-corrosive nature. These plates are therefore widely used in various industries, including power generation systems, pulp and paper processing, chemical manufacturing, desalination plants, marine engineering, and oil and gas exploration.
In order to meet various project requirements, SMO 254 plates and sheets are produced in different sizes and finishes. Options include thicknesses ranging from 3 to 150 mm, widths ranging from 1220 to 4200 mm and lengths ranging from 5000 to 18000 mm. Both hot-rolled, and cold-drawn manufacturing techniques are used. International Standards include ASTM, DIN, and JIS. Each plate is tested thoroughly using methods like PMI, NDT, hydrostatic, hardness, and flaring tests to verify performance.
Before dispatch, all products undergo thorough inspection and quality assurance testing. This testing includes raw material certification, radiography testing, and third-party certification. Each product is carefully packaged against damage during transport so that it reaches the customer in pristine condition. Traceability is assured from manufacturing to delivery, as full documentation is provided with every shipment. With a huge inventory of sheets, coils and plates, we offer timely availability, and speedy completion of customer orders.
