Amigo Impex manufactures and supplies Stainless Steel 422 bars and rods in Mumbai, India. We've produced, stocked and exported this grade, running cutting, machining, threading and testing at our own works.
422 stainless steel round bar is a hardenable martensitic stainless steel developed for high-temperature turbine duty, and we supply it as UNS S42200 bar to ASTM A565 Grade 616. Molybdenum, tungsten and vanadium form carbides that keep the steel strong where plain chromium grades soften. Hardened and tempered bar reaches 965 MPa tensile strength for blades and bolts under full design load. European drawings identify the same steel as 1.4935 or X20CrMoWV12-1. Aerospace orders call up the same alloy through AMS 5655, which uses a slightly wider composition window than ASTM A565 Grade 616; confirm which specification your drawing cites before ordering. Round bar spans 4 mm to 500 mm in diameter, with hex, square, flat, bright and forged profiles in 1 to 6 metres or custom-cut lengths.
Gas turbine blades, valve internals and aerospace fasteners are machined from this bar for power, oil and gas and defence programmes. As a reliable 422 stainless steel bar manufacturer and supplier, we are certified to AS 9120B, PED, ISO 9001:2015 and ISO 45001:2018. All our products are shipped alongside mill test certificates; we supply orders across India and export, with pricing quoted per kg in INR or USD.
We supply Stainless Steel 422 bars and rods against ASTM A565 Grade 616 in grade UNS S42200. The table sets out the size envelope, supply conditions, finishes and profiles we hold.
Orders for SS 422 bars run against ASTM A565 Grade 616. The specifications below cover the same chemistry for aerospace and turbine bolting applications.

| AMS 5655 | Hardened and tempered 422 bars, wire, forgings and forging stock for aerospace |
Type 422 follows the 12Cr-1Mo-V-W analysis pattern. Carbon at 0.20 to 0.25% allows the AISI 422 chemistry harden fully, while tungsten and vanadium carbides survive long tempering cycles.
| Element | Min % | Max % |
|---|---|---|
| Carbon (C) | 0.20 | 0.25 |
| Manganese (Mn) | 0.50 | 1.00 |
| Phosphorus (P) | - | 0.025 |
| Sulphur (S) | - | 0.025 |
| Silicon (Si) | - | 0.50 |
| Chromium (Cr) | 11.00 | 12.50 |
| Nickel (Ni) | 0.50 | 1.00 |
| Molybdenum (Mo) | 0.90 | 1.25 |
| Tungsten (W) | 0.90 | 1.25 |
| Vanadium (V) | 0.20 | 0.30 |
| Iron (Fe) | Balance | - |
The heat-treat condition determines which figures apply to the Grade 422 bar, so each table is labelled by that condition. Mixing values across conditions misstates a design margin.

The designations below cover the same 12Cr-Mo-W-V family, but they are cross-references, not identical chemistries. EN 1.4935 carries a lower tungsten band than UNS S42200, so a drawing calling for 1.4935 needs the actual EN 10302 analysis confirmed before substitution. Tell us which standard your drawing cites and we will certify against it.
| Country / Standard | Designation |
|---|---|
| USA (UNS) | UNS S42200 |
| Europe (EN / W.Nr.) | 1.4935 / X20CrMoWV12-1 |
| Japan (JIS) | SUH 616 |
| France (AFNOR) | Z35CD17 (not exact but closest equivalent) |
