Super Duplex Steel S32760 Pipes
Super Duplex Steel S32760 pipes, also known as ASTM A790 UNS S32760, are high-performance duplex stainless steel grades having a PREN (Pitting Resistance Equivalent Number) greater than 40. These pipes are known for their excellent resistance to chloride corrosion, outstanding mechanical strength, and exceptional toughness, which allows them to function consistently in the most demanding chemical, marine, and offshore environments. They are preferable to the standard duplex or austenitic grades due to their high chromium, molybdenum, and nitrogen content.
Super Duplex Steel S32760 Pipes Price In India
The price of ASTM A790 UNS S32760 pipe in India depends on the pipe type, dimensions, finish, and order volume. Here is a clear breakdown to help plan procurement.
Approximate Price Range:
Super duplex steel S32760 seamless pipes are priced between INR 1,800 and INR 4,500 per kg in India. Welded variants are more economical, ranging from INR 1,200 to INR 2,800 per kg depending on the specification.
Cost Per Foot (Approx.):
A standard 1-inch S32760 seamless pipe (Schedule 40) is priced at approximately INR 600 to INR 1,500 per foot. Larger diameters and thicker wall schedules will increase this cost.
Factors Affecting Price:
The 3 key factors that directly influence the final price:
- The cost of raw materials (especially nickel, molybdenum, and chromium).
- The pipe type and finish (seamless pipes are costlier than welded ones).
- The order quantity and any extra certifications needed, such as NACE, PED, or third-party inspections.

How To Choose The Right Super Duplex Steel S32760 Pipe Supplier
Choosing the right ASTM A790 UNS S32760 pipe manufacturer directly impacts material quality, project timelines, and total procurement cost. Evaluate 6 key factors before finalising a source.
Evaluate the manufacturer's technical expertise: Confirm the manufacturer has hands-on experience with duplex and super duplex grades. Ask for past project references specific to S32760 to validate expertise.
Check grade availability and product range: A reliable super duplex steel S32760 pipe supplier provides a wide range of diameters, schedules, and pipe types. The availability of standard and custom dimensions reduces project lead times.
Verify quality certifications and testing capabilities: Certifications such as PED, NACE MR0175, and ISO 9001 are non-negotiable. In-house tests like PMI, hydro testing, and ultrasonic inspection ensure that each pipe meets the required standards.
Examine the strength of raw material sourcing: The quality of raw billets and coils directly affects the final pipe's mechanical performance. Ask whether the supplier sources mill-certified raw material from approved vendors.
Assess customisation capabilities: Projects often require specific OD, wall thickness, or end finish combinations. Confirm the manufacturer can produce to custom dimensions without compromising on tolerances.
Review delivery timelines and supply capacity: For large-scale projects, supply consistency matters as much as quality. Verify that the super duplex steel S32760 pipes' price quoted includes a realistic delivery schedule backed by adequate inventory.

Super Duplex Steel S32760 Pipes FAQ's
Super Duplex Steel S32760 pipe is a high-alloy duplex stainless steel with a dual austenitic-ferritic microstructure. It contains 25% chromium, 3.5% molybdenum, 7% nickel, and 0.25% nitrogen, giving it a PREN above 40. This makes it one of the most corrosion-resistant pipe grades available for industrial use.
The price of super duplex steel S32760 pipes in India varies between INR 1,200 and INR 4,500 per kg, based on the pipe type (seamless or welded), outer diameter, wall schedule, and quantity purchased. Special certifications or non-standard sizes will result in higher costs. .
UNS S32760 seamless pipes are priced between INR 1,800 and INR 4,500 per kg in India. Welded variants start from INR 1,200 per kg. Final pricing depends on dimensions, finish, testing requirements, and order volume.
Super duplex steel S32760 pipes are manufactured to ASTM A790 and ASME SA790 standards. These cover both seamless and welded pipe forms. The pipes should comply with NACE MR0175 for sour (corrosive) service and PED 2014/68/EU for pressure equipment.
S32760 contains higher molybdenum (3.0–4.0%) and added tungsten and copper compared to S32750, giving it a slightly higher PREN (>40 vs. >40 for S32750, depending on the composition). Both are super duplex grades, but S32760 is preferred in more aggressive chloride and acidic environments.
Duplex Steel S32760 pipes range from ½ inch to 24 inches in outside diameter, with wall thickness schedules from Sch 5S to Sch XXS. Standard lengths are 6 metres and 12 metres. Custom lengths and sizes are available on request from a qualified ASTM A790 UNS S32760 pipe supplier on The Piping Mart.
