Amigo Impex is a super duplex S32760 bar manufacturer and supplier based in Mumbai. We have been producing and stocking Super Duplex S32760 bars & rods for over a decade.
Super Duplex S32760 (UNS S32760, EN 1.4501) is a 25Cr super duplex steel supplied as bar and rod to ASTM A276 and ASTM A479 / ASME SA-479. The chemistry sets 24.0 to 26.0% chromium against 6.0 to 8.0% nickel and 0.20 to 0.30% nitrogen; molybdenum runs 3.0 to 4.0%, and copper and tungsten add 0.50 to 1.00% each. That balance carries its pitting resistance equivalent (PREN) past 40, the minimum ASTM sets for this grade, so the bar holds up in seawater, brine and hot chloride streams. The annealed bar reaches a minimum tensile strength of 750 MPa and a yield strength of 550 MPa.
Our stock spans from 3 mm to 450 mm in diameter across various bar profiles, in 3 to 6 metre lengths. Cutting, machining, threading and testing happen in-house; the bar becomes shafts, fasteners and valve internals across offshore, marine, desalination and chemical plants.
Amigo Impex is certified to ISO 9001:2015, ISO 45001:2018 and other certifications. We ensure each batch is supplied alongside a mill test certificate for full product traceability.
Every Super Duplex S32760 round bar enquiry starts with the envelope below: the diameters, lengths, forms, finishes and tolerance classes we supply against ASTM A479 / ASME SA-479 and ASTM A276.
Three documents cover super duplex S32760 rods and bars supply, split between general-purpose and pressure-vessel service. ASME work takes the SA prefix; the design code names the governing document.
| Standard | Scope |
|---|---|
| ASTM A276 | General-purpose stainless bar and shapes, hot or cold finished |
| ASTM A479 / A479M | Stainless steel bars and shapes for boilers and other pressure vessels |
| ASME SA-479 | ASME code adoption of A479, identical requirements |
SA-479 fixes the chemistry of UNS S32760 bars within the limits below. Copper and tungsten mark the grade out, and the formula %Cr + 3.3 × %Mo + 16 × %N ≥ 40 on every heat.
| Element | Composition, % |
|---|---|
| Carbon (C) | 0.030 max |
| Manganese (Mn) | 1.00 max |
| Phosphorus (P) | 0.030 max |
| Sulphur (S) | 0.010 max |
| Silicon (Si) | 1.00 max |
| Chromium (Cr) | 24.0 to 26.0 |
| Nickel (Ni) | 6.0 to 8.0 |
| Molybdenum (Mo) | 3.0 to 4.0 |
| Copper (Cu) | 0.50 to 1.00 |
| Tungsten (W) | 0.50 to 1.00 |
| Nitrogen (N) | 0.20 to 0.30 |
| Iron (Fe) | Balance |
Annealed is the only condition listed in ASTM A479 for this grade; the properties below are per ASTM A276 (A479 caps hardness at 300 HBW). For cold-drawn bar (ASTM A276 Condition S: 860 MPa tensile, 720 MPa yield, 16% elongation, max. 335 HBW), explicitly state the condition in your enquiry. Yield is more than three times the 170 MPa minimum ASTM sets for annealed 316L bar; hardness is limited to a single maximum.
| Condition | Tensile Strength (min) | 0.2% Yield Strength (min) | Elongation (min) | Hardness (max) |
|---|---|---|---|---|
| Annealed | 750 MPa (109 ksi) | 550 MPa (80 ksi) | 25% | 310 HBW |
Drawings raised in Europe name this material 1.4501 and forging specifications call it F55; both map onto the super duplex S32760 bar stock we hold. The rows below tie designations together.
| Designation System | Designation |
|---|---|
| USA (UNS) | S32760 |
| Europe (EN / W.Nr) | 1.4501 (X2CrNiMoCuWN25-7-4) |
Diameter decides whether Super Duplex S32760 bars & rods ship ex-stock or roll to order, so check the window first. Profiles carry individual ranges; length stays common.
| Bar Form | Size Range |
|---|---|
| Round Bar | 3 mm to 450 mm diameter |
| Hex Bar | 2 mm to 100 mm across flats |
| Square Bar | 4 x 4 mm to 100 x 100 mm |
| Flat Bar | 2 to 100 mm thick x 10 to 500 mm wide |
| Length | 3 to 6 metres; cut to length |
The following Super Duplex Steel S32760 rod and bar types cover the profiles machine shops call for, all in the surface finishes and conditions shown above.
Bar bundles are issued from our Mumbai warehouse, strapped and edge-protected; bright or machined UNS S32760 round bar travels individually wrapped in wooden cases, each bundle marked with heat number, grade and order reference. As a stockist and exporter, we serve pan-India and ship to the USA, Gulf states, Europe and Asia by sea. Ex-stock bar dispatches in one to two working days; made-to-order rolling takes roughly 30 days.
Each ASTM A479 S32760 rod and bar order carries EN 10204 type 3.1 certification from the mill, backed by in-house checks before packing. Third-party inspection is arranged when an order requires witnessed release. Amigo Impex runs the quality system to ISO 9001:2015, carries ISO 45001:2018, holds PED plus AS 9120B approvals, and maintains heat-to-dispatch traceability.
Super Duplex S32760 bars & rods price levels sit between an indicative ₹650 and ₹900 per kg ($7.8–10.8/kg) on the Indian market; the number isn't fixed and tracks alloy surcharges. Export orders are billed in US dollars per kilogram under the agreed Incoterm, and diameter, shape, length, quantity, finish and inspection scope all move the quote.

Round Super Duplex S32760 bars and rods are available from 3 mm to 450 mm in diameter, hex to 100 mm across flats and square to 100 x 100 mm, in 3 to 6 metre lengths.
Indicatively, ₹650 and ₹900 per kg ($7.8–10.8/kg) buy Super Duplex S32760 rod in the Indian market; diameter, shape, quantity and finish move the final rate.
Equivalent designations for Super Duplex S32760 bar are EN 1.4501 (X2CrNiMoCuWN25-7-4) and F55 in forged form; bar supply runs to ASTM A276 and A479 / ASME SA-479.
No. 2507 and 1.4410 identify UNS S32750, a different super duplex grade; Super Duplex S32760 bar corresponds to 1.4501 and F55, so the two are certified separately.
Available shapes span round, hexagonal, square and flat bar, plus rectangular, hollow, threaded rod, bright, black and forged.
Cold-drawn, polished and centreless ground finishes are available on Super Duplex S32760 bright bar; black, rough turned, No.4, matt and BA apply to other types.
Custom lengths are routine, as Super Duplex S32760 bars and rods are cut in-house from 3 to 6 metre stock to the length ordered.
Amigo Impex supplies certified Super Duplex S32760 bars & rods cut to length from Mumbai stock. Contact us for availability and a current per-kg rate.
