Inconel 600 Plate, Inconel 600 Sheet, Alloy 600 Plate, Alloy 600 Sheet and ASTM B168 UNS N06600 Manufacturer & Supplier in India
We have been supplying Inconel 600 Sheets & Plates from our Mumbai warehouse for over 15 years to aerospace fabricators, EPC contractors, chemical plant engineers, nuclear power operators and oil and gas OEMs across more than 50 countries. Every plate and sheet we supply is ASTM B168 / ASME SB168 certified to UNS N06600 and ships with an EN 10204 3.1 Mill Test Certificate on every shipment, not on request.
Inconel 600 (Werkstoff Nr. 2.4816, JIS NCF 600, EN NiCr15Fe) is a solid-solution nickel-chromium alloy that performs reliably across a wider temperature and chemical environment range than any standard grade of stainless steel. It is the material engineers specify when operating conditions, chloride exposure, temperatures above 700°C, alternating oxidising and reducing atmospheres or nuclear coolant environments rule out the cheaper options.
Our warehouse carries the full product range: foil from 0.15 mm to heavy plate at 120 mm, cold-rolled and hot-rolled, in all standard finishes. Laser cutting, shearing, circle cutting and custom slitting are done in-house. If you need cut-to-size rather than full sheets, just specify your dimensions when enquiring.

Why Inconel 600 Resists Chloride Stress Corrosion Cracking
Chloride stress corrosion cracking (Cl-SCC) is one of the most dangerous failure modes in process plant engineering. It requires three conditions simultaneously: a susceptible material, tensile stress (residual or applied), and chloride ions above a threshold concentration at elevated temperature. Austenitic stainless steels, including 316L and 304L, are highly susceptible — failures can occur with no visible prior warning at chloride levels as low as 50 ppm above 60°C.
Inconel 600 is immune because its ≥72% nickel content places the alloy above the electrochemical threshold at which chloride-induced anodic dissolution — the driving mechanism of Cl-SCC can sustain itself. This is a thermodynamic immunity, not a kinetic resistance: the cracking mechanism literally cannot initiate in a high-nickel alloy under the conditions that destroy stainless steel. This is why Inconel 600 is specified for nuclear steam generator tube support plates, seawater heat exchanger shells, and brine handling equipment worldwide.

Welding, Forming & Machining Inconel 600 Sheet — Complete Fabrication Guide
Inconel 600 is one of the more weldable high-nickel alloys, but its work-hardening rate, thermal expansion coefficient, and sensitivity to sulphur contamination require attention during fabrication. The guidance below reflects best practices for typical industrial fabrication.
Recommended Welding Processes and Filler Metals for Inconel 600
All standard fusion welding processes are applicable. The choice of filler metal is critical — always use a matching or higher-nickel filler to avoid creating dilution zones with degraded corrosion resistance.
| Process | Filler Metal | AWS Classification | Notes & Best Use |
|---|---|---|---|
| GTAW / TIG | ERNiCrFe-7 | AWS A5.14 | Preferred for precision welds, thin sheet, and root passes. Best corrosion resistance in weld zone. |
| GTAW / TIG | ERNiCr-3 | AWS A5.14 | Alternative for general TIG welding; slightly higher strength deposit. |
| SMAW | ENiCrFe-3 | AWS A5.11 | Field welding and repair. Good deposition rate. Use for structural work where access limits TIG. |
| GMAW / MIG | ERNiCrFe-7 | AWS A5.14 | Higher deposition rate for production welding on thicker material (>6 mm). |
| SAW | ERNiCr-3 | AWS A5.14 | Heavy plate joining (>12 mm). Requires fluoride-basic flux. High productivity. |
| EBW / LBW | No filler | n/a | Electron beam / laser welding for thin-gauge aerospace and nuclear applications requiring minimal heat input. |
Pre-heat: Not required for Inconel 600 under standard fabrication conditions. Maintain interpass temperature below 150°C to control distortion in thin sheet.
Post-Weld Heat Treatment (PWHT): Not mandatory, but solution annealing at 980°C (1800°F) for 1 hour per 25 mm of thickness, followed by rapid cooling, is recommended for assemblies exposed to stress-corrosion risk or high-temperature cycling service. The anneal relieves residual weld stresses and re-dissolves any carbide precipitation in the heat-affected zone.
Critical contamination warning: Do not allow sulphur-bearing materials (marking inks, lubricants, some adhesives) to contact the metal surface during or before welding. Sulphur at temperature causes severe hot cracking in nickel alloy welds. Use only nickel-compatible lubricants and marking materials.
Cold Forming, Hot Forming and Machining Guidelines for Alloy 600
Cold Forming: Inconel 600 cold-forms well on standard press brake and roll-forming equipment, but work-hardens approximately 30–40% faster than 316L austenitic stainless. As a practical rule, increase the inside bend radius by 50% compared to the equivalent 316L operation. For tight-radius bends (< 1.5× material thickness), solution anneal the blank at 980°C before forming to achieve maximum ductility. Anneal again after significant cold work to restore corrosion resistance and avoid residual stress.
Hot Forming: Carry out between 870°C and 1175°C. The alloy becomes increasingly resistant to deformation below 870°C and risks cracking if forced. Above 1175°C, grain growth accelerates and mechanical properties degrade. After hot forming, always solution anneal to restore the full corrosion resistance of the alloy.
Machining: Use carbide tooling with positive rake angles and sharp cutting edges. Surface speeds should be 20–30% lower than for austenitic stainless steel — approximately 20–30 m/min for turning with carbide inserts. Use high feed rates and keep the tool engaged to prevent work-hardening the machined surface ahead of the cut. Flood coolant (water-soluble cutting fluid) is essential. Do not use sulphurised cutting oils.
Inconel 600 vs Inconel 625 vs Inconel 601 — How to Choose the Right Alloy
The three most frequently compared Inconel grades for high-temperature and corrosion-resistant applications are 600, 625, and 601. Each occupies a distinct performance envelope and price point. The comparison below covers the properties that drive specification decisions.
| Property | Inconel 600 (N06600) | Inconel 625 (N06625) | Inconel 601 (N06601) |
|---|---|---|---|
| Nickel Content | 72% min | 58% min | 58–63% |
| Chromium | 14–17% | 20–23% | 21–25% |
| Molybdenum | Not present | 8–10% | Not present |
| Aluminium | Not present | Not present | 1.0–1.7% (key differentiator) |
| Niobium | Not present | 3.15–4.15% | Not present |
| Max Service Temp. | 1093°C (2000°F) | 982°C (1800°F) | 1175°C (2150°F) — highest of three |
| Tensile Strength | 655 MPa | 930 MPa | 650 MPa |
| Cl-SCC Resistance | Excellent | Excellent | Excellent |
| Oxidation Resist. | Excellent to 1093°C | Good to 982°C | Superior above 1050°C |
| Pitting Resistance | Good | Superior (Mo) | Good |
| Relative Cost | Base (lowest) | +25–35% | +10–15% |
| ASTM Std (sheet) | ASTM B168 | ASTM B443 | ASTM B168 |
| Choose when… | High-temp + Cl-SCC risk; budget is a constraint | Seawater / strong acid / offshore / high mechanical load | Continuous >1050°C; high-aluminium oxidation scale required |
Inconel 625 → Maximum corrosion resistance in seawater, strong acids, and offshore applications.
Inconel 601 → Continuous service above 1050°C where aluminium-enhanced oxidation resistance is required.

The following table details the key applications of Inconel 600 flat-rolled products by industry, and critically explains what specific failure mode the alloy prevents that drives the specification decision. Engineers do not specify Inconel 600 because it is the ‘best’ alloy in general; they specify it because the operating conditions create a specific failure mode that cheaper alternatives cannot survive.

Inconel 600 Sheet & Plate Price — India FOB, CIF & Export Pricing
Inconel 600 plate prices are driven primarily by the LME (London Metal Exchange) nickel index, since the alloy is over 72% nickel by weight. A $1,000/MT move in nickel translates to approximately $720/MT movement in alloy raw material cost. For this reason, quotations are tied to the LME nickel spot rate on the day of issue and are valid for 24–48 hours only.

| Export Price (plates, FOB Mumbai) | $33 – $38 per kg |
| Metric Tonne Price | $33,000 – $38,000 per metric ton |
