When you’re responsible for a refinery shutdown, an aerospace build, or a marine installation, the last thing you can risk is a plate that fails. A single wrong grade can cause corrosion, leaks, or catastrophic shutdowns. That’s why engineers, procurement managers, and EPC contractors worldwide rely on Inconel 625 Plates—and that’s exactly what Navgraha Steels INC delivers.
We are not just another plate stockist. We are a partner who thinks like an engineer, delivers like a stakeholder, and exports like a global logistics specialist.
Inconel 625 is a nickel-chromium-molybdenum-niobium alloy that has become the backbone of industries that can’t afford material failure. Unlike stainless steels that pit in seawater or ordinary nickel alloys that weaken at high temperatures, Inconel 625 plates thrive in extremes:
That’s why global buyers trust Inconel 625 plates for offshore rigs, aerospace engines, chemical reactors, and nuclear plants.
If you’re asking “Where exactly can I use Alloy 625 plates?” — here are real-world answers:
Every plate supplied by Navgraha Steels INC is fit for purpose, certified, and traceable.
| Property | Value (Approx.) | Buyer Advantage |
|---|---|---|
| Tensile Strength | ~930 MPa | High load-bearing capacity |
| Yield Strength | ~450 MPa | Withstands stress without deformation |
| Elongation | 30–40% | Good ductility for fabrication |
| Hardness (Brinell) | 200–250 HB | Tough, durable plates |
| Service Temperature Range | −196°C to 982°C | Performs from cryogenic to high heat |
| Fatigue & Creep Resistance | Excellent | Long service life under cyclic stress |
| Element | % Composition | Function in Alloy |
|---|---|---|
| Nickel (Ni) | ≥58% | Base element, corrosion resistance |
| Chromium (Cr) | 20–23% | Oxidation & scaling resistance |
| Molybdenum (Mo) | 8–10% | Strengthens against reducing acids |
| Niobium + Tantalum (Nb+Ta) | 3.15–4.15% | Prevents stress cracking, adds toughness |
| Iron (Fe) | ≤5% | Balance element |
| Cobalt (Co) | ≤1% | Impurity control |
| Others (Mn, Si, Al, Ti) | ≤1% each | Minor strengthening agents |
One of the biggest project risks is rejection during inspection because the supplied plate doesn’t match the specified code. At Navgraha Steels INC, every Inconel 625 plate we supply is backed by recognized global standards:
This ensures your order will pass third-party inspections, consultant approvals, and international audits without delay.
Buyers often face a simple but costly pain point: “The size I need isn’t in stock.”
At Navgraha Steel, we maintain ready inventory to avoid downtime:
| Dimension | Availability |
|---|---|
| Thickness | 2 mm to 100 mm |
| Width | 1000 / 1250 / 1500 / 2000 mm |
| Length | 2000 / 2500 / 3000 mm (custom cut-to-size available) |
| Finishes | Hot Rolled, Cold Rolled, Annealed, Polished |
With us, you save time, machining cost, and procurement stress.
What keeps buyers awake at night? “Will the plates survive long-term exposure in seawater, HCl, or oxidizing acids?”
Inconel 625 solves this with its unique chemistry:
That’s why it’s the go-to material for marine pipelines, chemical reactors, and high-temperature exhaust systems.
Engineers want alloys that are workable, not problematic. Inconel 625 offers:
With Navgraha Steel’s technical support, your workshop achieves faster fabrication and fewer rejections.
Not all suppliers think beyond selling. At Navgraha Steels INC, we act as solution partners:
With us, buyers don’t just get plates—they get assurance, compliance, and confidence.
Procurement teams prefer one trusted supplier for all nickel alloy needs. Alongside Alloy 625 plates, we also supply:
This makes Navgraha Steels INC a one-stop source for global buyers.
Global buyers often fear material damage during transit or delayed shipments. At Navgraha Steels INC, we eliminate this worry with export-grade logistics.
Export Reach:
Every plate reaches on time, intact, and compliant with international standards.
The most common pain point: “What if I order the wrong grade or thickness?”
Here’s a quick checklist to avoid costly errors:
With Navgraha Steel, you get consulting-level guidance plus supply, reducing risks at every stage.
Rejected plates = project delays. To protect buyers, we provide complete documentation and traceability:
This ensures smooth audits, consultant approvals, and zero rejection risk.
Grade 1 is annealed, while Grade 2 is solution annealed and stress relieved for higher strength.
Inconel 625 excels in marine & high-temp strength; Hastelloy C22 is better for acid-heavy environments. Choice depends on your project.
Aerospace, marine, oil & gas, chemical, and nuclear power sectors.
Navgraha Steels INC supplies certified plates with full EN 10204 traceability, ready for export worldwide.
Time lost in waiting = money lost in shutdowns.
