Amigo Impex, a stainless steel bars and rods manufacturer and stockist in Mumbai, India, has supplied SS products to domestic and export markets since 2013. Machine shops, OEMs and fabricators order from our stainless steel bar stock, including round, square, hexagonal and flat sections to ASTM A276 / ASME SA-276, with A479 for pressure duty and A564 for the precipitation-hardening set. Seventeen grade designations stay on the shelf, running from 304 and 316L through 904L up to 440C and 17-4PH. Rounds span 3 mm to 610 mm in diameter, and cutting, machining, and threading run in-house on all lengths up to 6 metres.
Grade selection across stainless steel products starts with corrosion resistance, followed by strength and machinability, covering austenitic, martensitic, ferritic and precipitation-hardening families. Surface conditions run from black hot-rolled stock to bright cold-finished bar. Pricing is quoted per kilogram in INR or USD, with consignments supplied across India and exported to the USA, Europe, the Gulf and Asia. Every order is dispatched with a comprehensive EN 10204 3.1 mill test certificate. Our company holds AS 9120B, PED, ISO 9001:2015, and ISO 45001:2018 certifications, under which our in-house team directly manages all product testing and packaging operations. As a stainless steel bar supplier, Amigo Impex confirms available grades, sizes and finishes against your enquiry, with same-day stock confirmation from our Mumbai sales desk.
Stainless steel bars and Rods orders are defined by the parameters listed here: standards, grades, sections, sizes, lengths, surface state and paperwork. The table shows whether a drawing or purchase order can be fulfilled from available stock.
Five ASTM specifications govern the supply, four of them ASME-adopted A276 leads the ordering, A479 answers pressure vessel work, A484 fixes general requirements, and A564 controls the pH grades.
| Specification | Coverage |
|---|---|
| ASTM A276 / ASME SA-276 | Stainless steel bars and shapes; the primary ordering basis |
| ASTM A479 / ASME SA-479 | Bars and shapes for boilers and other pressure vessels |
| ASTM A484 / A484M | General requirements covering stainless bars, billets and forgings |
| ASTM A564 / ASME SA-564 | Age-hardening (PH) stainless bars and shapes |
| ASTM A565 / A565M | Martensitic stainless bars for high-temperature service (Grade 616 = Type 422) |
Corrosion resistance leads grade selection for stainless steel bars, with strength, hardness and machinability weighed behind it. Seventeen stocked variants span the austenitic, martensitic, ferritic and precipitation-hardening families below.
The default austenitic bar, UNS S30400, goes into fasteners, shafts, sinks and food plant components.
304L rod holds carbon low for welded assemblies. UNS S30403 suits dairy, brewery and water treatment work.
Stainless Steel 310 bar, UNS S31000, shrugs off furnace scale in kiln components and annealing fixtures.
Molybdenum equips 316 and 316L bar, UNS S31600 and S31603, for chloride service: marine fittings, chemical plant, coastal architecture.
317 and 317L rods carry extra molybdenum, certified UNS S31700 and S31703. Scrubbers and pulp mill hardware take most of it.
Titanium-stabilised 321 bar, UNS S32100, resists carbide precipitation through welding heat in exhaust assemblies.
347 bar answers the same range with niobium stabilisation; UNS S34700 feeds refinery and boiler components.
Copper-bearing 904L rod, UNS N08904, resists sulphuric acid circuits and fertiliser plants.
The entry martensitic grade, 410 bar, UNS S41000, hardens for pump shafts, bolting and valve trim.
420 bar, UNS S42000, reaches cutlery hardness after heat treatment. Moulds, dies and surgical tooling cut from it.
Stainless Steel 422, UNS S42200, is supplied to ASTM A565/A565M as Grade 616, not to A276. It holds strength at turbine temperatures, for blades, stems and hot-section bolting.
430 bar heads the no-deliberate nickel addition ferritic family; UNS S43000 covers trim, spindles and appliance shafts.
Bearing makers grind 440C and 440B bars, UNS S44004 and S44003, into races, balls, knives and gauges.
15-5 PH rod, UNS S15500, ages in one furnace cycle for pump internals and aerospace fittings.
17-4 PH bar, UNS S17400, pairs copper-driven ageing with martensitic strength. Valve stems and gears are machined from it.
PH 13-8 bar, UNS S13800, brings vacuum melt cleanliness and toughness to landing gear links and flight critical fasteners.
Spring shops draw on 17-7 PH rod, UNS S17700, where formability before ageing matters most.
Stocked spans per section appear in the table; flat stainless steel bar and other dimensions outside these ranges are supplied to order.
| Bar Section | Measured By | Stocked Span |
|---|---|---|
| Round Bar | Diameter | 3 mm to 610 mm |
| Square Bar | Side | 4 mm to 100 mm |
| Hex Bar | Across Flats | 2 mm to 100 mm |
| Flat Bar | Thickness | 2 mm to 150 mm |
| All Sections | Length | 1 to 6 metres, cut to size |
Values below are theoretical, computed at 7.90 g/cm³, the density published for 304 / EN 1.4301 in EN 10088-1. Martensitic and ferritic bars (410, 420, 430) are lighter at about 7.70–7.75 g/cm³; 316, 316L and 904L are heavier at about 8.00 g/cm³. Confirm actual weight against the mill test certificate.
| Diameter (mm) | Weight (kg/m) @ 7.90 |
|---|---|
| 10 | 0.62 |
| 12 | 0.89 |
| 20 | 2.48 |
| 40 | 9.93 |
| 100 | 62.05 |
5 types cover the stainless steel bar range, split by rolled shape and production route. Hex and square stock saves machining set-up.
Five surface conditions run through the stainless steel rod and bar stock: black HRAP with a machining margin, cold drawn and ground bright stock at tighter size, plus peeled routes for larger diameters.
Strapped bundles move stainless steel bars and rods inland, and export lots travel in timber cases under HS code 7222. Tags record size, grade and heat. Despatch spans pan-India and exports serve Gulf, American, European and Asian markets; ready stock clears inside 1 to 2 days, production material in about 30 days.
Stainless steel bar testing runs in-house ahead of packing: PMI, hardness and dimensional checks on each lot, reported on the EN 10204 3.1 mill test certificate. Independent inspectors can witness the work; we hold AS 9120B, PED, ISO 9001:2015 and ISO 45001:2018 certifications.

The difference is trade wording rather than a product split: rod names the smaller diameters, bar the heavier sections, and governing standards don't change.
Available sizes span 3 mm to 610 mm rounds, 100 mm squares and hex, 150 mm flat thickness and 6 metre lengths.
Four families cover the list: austenitic 304 through 904L, a martensitic and ferritic run 410 to 440C, and precipitation hardening 15-5 PH, 17-4 PH, PH 13-8 and 17-7 PH.
The phrase widens the round enquiry to every rolled section held: square, hex and flat bar to specified dimensions and cut lengths.
Yes, SS bright bar ships cold-drawn or in a centreless cold-drawn and ground condition, with peeled stock above the drawing range.
Yes, a 12 mm round bar in grade 304 is a regular stock item at a theoretical 0.89 kg per metre.
Custom lengths are standard service: in-house saws cut any bar to size, and there's no full-length commitment.
