Sumer Metal Industries Private Limited, based near Mumbai, India, is a reputable manufacturer, supplier, and exporter of high‑grade stainless steel products including sheets, plates, and coils. While their main offerings include grades like 304 and 316, they also handle specialized duplex grades—such as UNS S31500—under ASTM/ASME A240/SA240 specifications, for both domestic and export markets.
UNS S31500 is covered by ASTM A240 / ASME SA240 (flat products) and ASTM A789 / A790 (tubes/pipes) standards. Sumer Metal Industries supplies in accordance with these standards in sheet, plate, and coil form, with customised dimensions and surface finishes per customer requirements.

UNS S31500 is a duplex stainless steel alloy known for its superior strength and resistance to corrosion, especially in chloride-rich environments. This alloy combines the desirable properties of both austenitic and ferritic stainless steels, offering high mechanical strength, excellent resistance to pitting and crevice corrosion, and improved stress corrosion cracking resistance. These characteristics make UNS S31500 a popular choice in industries such as chemical processing, oil & gas, marine applications, desalination plants, and pulp & paper production.
Sheets, plates, and coils manufactured from UNS S31500 are widely used in structural and pressure-bearing applications where durability, performance under harsh conditions, and cost efficiency are critical. The material is available in hot-rolled and cold-rolled forms, with customizable finishes including 2B, BA, No.1, No.4, and mirror polish depending on the application. These products are suitable for fabrication and welding, although some precautions must be taken due to the duplex structure
