Stainless Steel 310S Pipes

Duplex Super Duplex Plate Sheet Supplier in India

Duplex and Super Duplex Plate Sheet are high-strength stainless steel flat products used in industries where corrosion resistance, chloride stress corrosion cracking resistance, and mechanical strength are critical. Duplex grades such as UNS S31803 and UNS S32205 are commonly used for marine, chemical, offshore, heat exchanger and pressure vessel applications. Super Duplex grades such as UNS S32750 and UNS S32760 offer higher chromium, molybdenum and nitrogen content for more aggressive environments such as seawater, desalination, oil & gas and offshore platforms.

We supply Duplex and Super Duplex Plate Sheet in various thicknesses, widths, lengths, finishes and cut sizes with proper material test certificates, marking, inspection support and export-ready packaging.

Duplex and Super Duplex Plate Sheet Overview

Duplex stainless steel is a two-phase stainless steel that combines austenitic and ferritic microstructures. This balanced structure gives duplex grades better strength than many standard austenitic stainless steels while maintaining good corrosion resistance and weldability. Super Duplex stainless steel is an upgraded category designed for more severe service conditions, especially where high chloride exposure, seawater, chemical processing or high mechanical load is involved.

Our Duplex Super Duplex Plate Sheet range is suitable for fabrication, pressure equipment, tanks, heat exchangers, offshore structures, process equipment, shipbuilding and heavy engineering projects. We help customers choose the correct grade, thickness and finish based on design pressure, corrosion environment, fabrication method and project documentation requirements.

Available Duplex and Super Duplex Grades

We supply a wide range of duplex and super duplex stainless steel plate and sheet grades, including:

• Duplex UNS S31803 Plate Sheet
• Duplex UNS S32205 Plate Sheet
• Duplex 2205 Plate Sheet
• Super Duplex UNS S32750 Plate Sheet
• Super Duplex UNS S32760 Plate Sheet
• SAF 2205 and SAF 2507 equivalent grades
• ASTM A240 / ASME SA240 Duplex and Super Duplex Plates

UNS S32205 is one of the most commonly used duplex grades because it offers a good balance of strength, corrosion resistance and cost efficiency. UNS S32750 and UNS S32760 are preferred when the application requires higher resistance to pitting, crevice corrosion and chloride stress corrosion cracking.

These ASTM A321 Stainless Steel Welded 310S Pipes undergo several tests such as Mechanical test, Rockwell hardness test, chemical test, intergranular corrosion test, positive material test, flattening test, flaring test, and third-party inspection. The SS 310S Welded Pipes has wide use in cryogenic structures, food preparing hardware, falters, toughening covers, suppresses, answers, ignitions chambers and burners, headstrong anchor jolts, thermo wells, lead pots, coal gasifier inward parts, Pipe holders for oil refining and steam boilers, brilliant cylinders, ovens, fluidized bed combustors. It is also used for intermittent service at temperatures up to 1040°C. Grade 310S (UNS S31008) is used when the application environment involves moist corrodents in a temperature range lower than that which is normally considered a “high temperature” service. SS 310S Welded Pipes have wonderfully superior formability and can be welded through good grace by all standard means. These 310S Stainless Steel Pipes offered by us are known for their leak-proof nature, seamless finishing and durability features.
