Duplex F51 Sheets, Plates, and Coils are premium-grade stainless steel products composed of a balanced microstructure of austenite and ferrite. Also known by its UNS designation S31803 or EN 1.4462, Duplex F51 is engineered to deliver exceptional strength and superior resistance to corrosion, particularly in chloride-rich environments. It combines the best properties of austenitic and ferritic stainless steels, offering double the strength of standard grades like 304 or 316 stainless steel. These characteristics make it a preferred choice for demanding industrial applications. l

At Sumer Metal Industries Private Limited, we specialize in manufacturing, supplying, and exporting high-quality Duplex F51 Sheets, Plates, and Coils that meet international standards such as ASTM A240, A182, and A276. Our products are available in various thicknesses, widths, and finishes to cater to the diverse needs of our global clientele. Each sheet or coil undergoes rigorous quality control and is accompanied by mill test certificates, ensuring full traceability and compliance.
One of the defining features of Duplex F51 is its excellent corrosion resistance, particularly against pitting, crevice corrosion, and stress corrosion cracking. Its high chromium (21–23%), nickel (4.5–6.5%), and molybdenum (2.5–3.5%) content, along with nitrogen additions, give it a high PREN (Pitting Resistance Equivalent Number), often above 35. These properties make F51 ideal for use in offshore oil rigs, chemical processing equipment, marine environments, desalination plants, and structural applications where exposure to harsh conditions is common.
