Super Duplex Steel S32760 Stud Bolts
Super Duplex Steel S32760 stud bolts are used when a single fastener must provide both high strength and corrosion resistance. The material has a mixed austenitic and ferritic structure, enhancing strength and resistance to stress corrosion cracking. S32760 also has good pitting and crevice corrosion resistance in chloride environments. These bolts are widely used in offshore platforms, seawater systems, and chemical processing units where the standard stainless steel grades may not be reliable over time.
Price of Super Duplex Steel S32760 Stud Bolts
Super duplex S32760 stud bolt prices depend on size, material grade, and certifications. Costs also shift based on order volume and supplier location.
Approx Price Range
Super duplex steel S32760 stud bolts price starts from ₹305/piece, depending on the size, thread form, and certification requirements. Prices of super duplex steel S32760 stud bolts may vary from one supplier to another due to the availability of raw materials and the local market conditions.
Price Per Unit / Kg
On a per kg basis, pricing usually falls between ₹250/kg-₹2,300. Higher diameter bolts cost more per unit, but bulk orders on standard sizes can bring the per kg rate down meaningfully.
Factors Affecting Price
The price is based on raw material costs, especially molybdenum and nickel, since these constitute a large part of the S32760 cost. Bolt size, length, and thread specifications also impact the price. Certifications such as NACE MR0175 or DNV increase the testing and documentation costs. Surface treatments or coatings add to the processing cost. Order volume impacts the per-unit cost, and shorter delivery times tend to raise the total cost as a result of priority production and handling.
Types of Super Duplex Steel S32760 Stud Bolts
Super duplex steel S32760 stud bolts are commonly available as:
- Fully Threaded Stud Bolts
- Double End Stud Bolts
- Tap End Stud Bolts
- Hex Head Bolts in S32760 grade
Selection depends on the flange type, joint design, and pressure rating of the system.

How to Choose the Right Super Duplex Steel S32760 Stud Bolts Supplier?
Picking the right supplier for S32760 stud bolts takes more than comparing prices. Material availability, certifications, and documentation reliability all matter.
Supplier Selection Criteria
Not all super duplex steel S32760 stud bolt suppliers stock this grade regularly. Confirm they have it available and not just sourced on order each time. Suppliers with offshore or oil and gas project experience understand documentation requirements better and are generally more reliable for this material.
Technical Considerations
ASTM A182 and ASME SA182 compliance is the baseline. Verify NACE MR0175 requirements for your offshore and subsea projects and check that the PREN value in the test report is as per your project. The thread form must match your flange spec before any order goes through.
Quality & Certification Check
Request heat certificates, third-party chemical and mechanical test reports, and dimensional records. Super duplex steel S32760 stud bolts suppliers working with certified projects will have these on file. Delays in documentation delivery usually signal deeper supply chain issues.
Procurement Tips for Bulk Orders
The price of super duplex steel S32760 stud bolts is highly dependent on the molybdenum rates, so it is recommended to lock the price in case of bulk orders. Always request a sample batch inspection before full shipment. Lead times for non-standard lengths can stretch, so factor that into your project schedule.
