Duplex and Super Duplex Steel Flange
The duplex and super duplex steel flange is a forged stainless steel component designed for high‑pressure piping systems. It is manufactured from duplex grades UNS S32205 and S31803 and super duplex grades UNS S32750 and S32760. The flanges conform to ASME B16.5 and EN 1092 dimensions and meet ASTM A182/ASME SA182 specifications such as F44, F45, F51, F53, F55, F60 and F61. Size offerings cover nominal pipe sizes from ½ in to 48 in (NPS ½‑48). Pressure ratings range from 150 # to 2500 # and temperature capability spans - 200 °C to 300 °C.
Available surface finishes include smooth, blasted and electro‑polished. Duplex alloys combine ferrite and austenite, giving them roughly twice the yield strength of conventional austenitic grades. Super duplex variants typically deliver yield strengths around 600 MPa and exhibit superior resistance to chloride‑induced stress corrosion cracking. In the industry, typical duplex flange yield strength is about 450 MPa and pitting resistance equivalent numbers (PREN) lie between 30 and 40.
End users such as oil‑field engineers, chemical plant designers and shipbuilding contractors select these flanges for pipelines handling corrosive media. Export packaging is usually on wooden pallets or in robust cases; buyers should confirm grade, size, pressure class, finish, Incoterm and payment terms directly with S. K. Forgefit Llp.
| Material | Duplex Stainless Steel UNS S32205/S31803; Super Duplex Stainless Steel UNS S32750/S32760 |
| Standard | ASME B16.5, EN 1092, ASTM A182/ASME SA182 (F44, F45, F51, F53, F55, F60, F61) |
| Size Range | NPS ½ - 48 in (DN 15 - 1219 mm) |
| Pressure Rating | 150 # - 2500 # (typical 150 - 2500 psi) |
| Temperature Rating | - 200 °C to 300 °C |
| Finish | Smooth, blasted, electro‑polished |
| Typical Yield Strength | typical 450 MPa for duplex, 600 MPa for super duplex |
| Typical PREN | typical 30 - 40 |
| Typical Dimensional Tolerance | ANSI/ASME B16.5 tolerances (typical ±0.13 mm for flange bolt circle) |
S. K. Forgefit Llp is located at Survey No.255, Plot No.23/24, Rivera Industrial Area, Shapar, Rajkot, Gujarat 360024, India. It is listed with a harbor trust tier, indicating a verified business profile, though its response rate is currently 0 % and average response time is not recorded. The company specialises in forging and machining of stainless steel components for industrial sectors.
The listing states that the flanges are exported with wooden pallet or case packaging and that pricing follows market conditions, but it does not disclose minimum order quantities, lead times or specific payment terms. Prospective buyers should therefore request a formal quotation and confirm any certification or test report requirements directly with the supplier.
Duplex and super duplex steel flanges are engineered for demanding applications in oil and gas, chemical processing, and marine environments where corrosion resistance and mechanical strength are critical. Available in grades such as UNS S32205, S31803, S32750, and S32760, these flanges meet ASME B16.5 and EN 1092 standards across sizes from NPS 1/2 to NPS 48. Super duplex variants offer roughly double the yield strength of conventional austenitic stainless steel with superior chloride stress corrosion cracking resistance. Pricing reflects current market conditions for specialty stainless steel forgings and is influenced by raw material surcharges and order volume. Export packaging typically follows wooden pallet or case standards for secure international transit.

Sourcing Duplex and Super Duplex Steel Flange from S. K. Forgefit Llp - India Import Guide
Before placing an order, verify that the flange grade, size, pressure class and finish match the engineering specifications of the intended pipeline. Request the mill test report and, if required, a third‑party certification confirming compliance with ASME B16.5 and EN 1092. Confirm that the supplier can provide traceability for the UNS grade and that the packaging meets your handling requirements.
Discuss logistics early; typical export packaging is on wooden pallets or in sturdy cases, but the exact Incoterm and lead time must be agreed with S. K. Forgefit Llp. Because the response rate is currently zero, allow extra time for communication and negotiate clear payment milestones, such as a T/T advance against a commercial invoice.
Arrange for pre‑shipment inspection or third‑party quality audit if your project requires it. Inspection should cover dimensions, surface finish, material composition and pressure‑class markings. Ensure that the final shipping documents include the certificate of conformity, packing list and bill of lading to facilitate customs clearance in the destination country.
