Amigo Impex manufactures, supplies, and stocks Inconel 660A bars and rods in Mumbai, India, with worldwide export capability. Operating since 2013, we carry out cutting, machining, threading, fabrication, testing, and packing in-house.
Inconel 660A (UNS S66286), traded worldwide as A-286, is a precipitation-hardening iron-nickel-chromium superalloy. We supply bar stock to AMS 5731 and AMS 5732 from 5 mm to 127 mm diameter (the 5.00 in. limit of those specifications). Above 127 mm and up to 500 mm, we supply to ASTM A453 / ASTM A638 Grade 660, or as AMS-conforming stock for forging. Age hardening gives the grade a minimum tensile strength of 895 MPa (130 ksi) under SA-453 Grade 660 Class A.
We hold 60 to 70 tonnes of Inconel Bars & Rods alloy stock, and our firm is certified to AS 9120B, PED, ISO 9001:2015, and ISO 45001:2018. This data applies strictly to grade 660A. Send your size list for an immediate stock confirmation. For procurement, visit the official Amigo Impex website.
The specification table summarises the key purchasing parameters for Inconel 660A bars, including standard, grade, diameter, length, shape, condition, finish, and compliance. Condition and certification requirements are explained below.
Bar and rod supply runs against AMS 5731, AMS 5732, AMS 5737 and AMS 5895, and to ASTM A453 / ASME SA-453 Grade 660 Class A and ASTM A638 Grade 660. Sheet and welding-wire specifications do not apply here.

The table lists room-temperature requirements for Inconel A286 round bars in the fully hardened condition, alongside indicative values for solution treated bar. Figures for the solution treated condition are typical and are not specification minimums. AMS 5731 controls hardness and requires the bar to meet the aged properties after ageing.
| Property | AMS 5731 (Solution Treated, typical) | SA-453 Gr. 660 Cl. A (Solution Treated & Aged) |
|---|---|---|
| Tensile Strength | around 620 MPa (90 ksi) | 895 MPa (130 ksi) min |
| Yield Strength (0.2% offset) | around 250 MPa (36 ksi) | 585 MPa (85 ksi) min |
| Elongation in 4D | around 40% | 15% min |
| Reduction of Area | Not specified | 18% min |
| Brinell Hardness | As specified in AMS 5731 | 248 to 341 HB |
| Condition | Solution treated only | Solution treated and precipitation-hardened |

Bars are bundled and packed in wooden or metal cases to stop rust and transit damage. Export consignments ship from our facility to Asia, Africa, Europe, Australia, North America and South America. Delivery is not limited to ex-warehouse dispatch: as an Inconel 660A Bars & Rods exporter, we arrange doorstep transport PAN India and full export documentation.
Each consignment of Inconel 660A bars leaves from our Mumbai warehouse with a mill test certificate from the original mill or our own laboratory. Test coverage spans chemical analysis, tensile and hardness testing, ultrasonic inspection, stress rupture testing where the specification calls for it, and PMI checks. Third-party inspection is supported on request.
Inconel 660A bars and rods are priced at approximately ₹2,000–₹4,700 per kg in the Indian market, equivalent to around US$21–US$49 per kg for international buyers, based on current currency conversion. Pricing varies according to shape, order quantity, surface finish, heat-treatment condition, testing, and certification. Nickel-market movements and export requirements may also affect the final quotation.

Yes. Inconel 660A is the same alloy as A-286 bar; both names describe UNS S66286. The trade name does not alter certification.
UNS S66286 is the UNS number for Inconel 660A bars and rods, and it is the same designation covering A286 and Alloy 660A material.
5 mm to 500 mm diameters of Inconel 660A round bar are available, with custom cutting on request.
You should order Inconel 660A bar to AMS 5732 for material supplied solution treated and precipitation-hardened. Choose AMS 5731, where machining comes first and age hardening follows.
The equivalent grade of Inconel 660A bar is 1.4980 (X6NiCrTiMoVB25-15-2) in Europe, SUH 660 in Japan and GH2132 in China.
The price of Inconel 660A bars and rods runs from ₹2,000 to ₹4,700 per kg in India and US$21–US$49 per kg internationally. Diameter, condition, quantity and testing shift the final figure.
Yes. Inconel 660A bar can be machined into high-temperature bolts and studs; ASTM A453 Grade 660 Class A exists specifically for such bolting, with a tensile floor of 895 MPa (130 ksi).
Round, square, hex, flat, forged and bright bar shapes are available in Inconel 660A, finished black, centreless ground, bright, rough turned or polished.
