Inconel 625 Sheets Supplier & Exporter – Navgraha Steels INC, Mumbai, India

When engineers and procurement managers are tasked with sourcing materials for high-risk projects, the biggest fear is: “What if the sheets corrode, fail under heat, or get rejected in inspection?”
This is where Inconel 625 Sheets make the difference—and at Navgraha Steels INC, Mumbai, we ensure you receive certified, traceable, and export-ready sheets trusted by global industries.

What Are Inconel 625 Sheets & Why Do Buyers Choose Them for Critical Projects?

Inconel 625 is a nickel-chromium-molybdenum-niobium alloy designed to withstand extremes:

  • Resistant to seawater corrosion, oxidizing & reducing acids.
  • Maintains strength without heat treatment.
  • Stable from cryogenic temperatures (−196°C) up to 982°C.

Buyers choose it because ordinary stainless steel pits in seawater, mild alloys crack under high stress, and uncertified supplies get rejected in audits. Inconel 625 sheets give you assurance, compliance, and performance you can stake your project on.

Applications of Alloy 625 Sheets Across Aerospace, Marine, Chemical & Energy Industries

Every industry has unique risks—but they all rely on Inconel 625 sheets:

  • Aerospace: Jet engine exhaust liners, turbine ducting, heat shields.
  • Marine & Offshore: Seawater piping, splash zone sheathing, subsea equipment.
  • Chemical Processing: Acid tanks, pollution scrubbers, reactor linings.
  • Energy & Power: Nuclear reactor components, oil & gas riser systems, power plant flue gas systems.

Wherever failure is not an option, Alloy 625 sheets are the industry’s trusted choice.

 Chemical Composition of Alloy 625 Sheets (UNS N06625 / Werkstoff Nr. 2.4856)

Element % Composition Function in Alloy
Nickel (Ni) ≥58% Base element, corrosion resistance
Chromium (Cr) 20–23% Oxidation resistance
Molybdenum (Mo) 8–10% Strengthens against reducing acids
Niobium + Tantalum (Nb+Ta) 3.15–4.15% Prevents cracking, adds toughness
Iron (Fe) ≤5% Balance element
Cobalt (Co) ≤1% Controls impurities
Others (Mn, Si, Al, Ti) ≤1% each Minor strengthening effects

International Standards & Equivalent Grades of Inconel 625 Sheets

One of the biggest risks for buyers is audit rejection when material doesn’t match project codes. That’s why every Inconel 625 sheet from Navgraha Steels INC is certified to international standards:

  • ASTM B443 / ASME SB443
  • AMS 5599 / AMS 5666
  • NACE MR0175 / ISO 15156 for sour service
  • UNS N06625 / Werkstoff Nr. 2.4856

This ensures consultant approvals, EPC acceptance, and third-party inspections worldwide.

Thickness, Width & Size Range of Alloy 625 Sheets

Buyers hate hearing “not in stock.” At Navgraha Steels INC, we maintain ready inventory to match your project needs:

Dimension Availability
Thickness 0.5 mm to 20 mm
Width 1000 / 1250 / 1500 / 2000 mm
Length 2000 / 2500 / 3000 mm (custom cut-to-size available)
Form Sheets, Blanks, Cut Pieces

This flexibility saves you time, machining cost, and material wastage.

Surface Finishes & Corrosion Resistance of Inconel 625 Sheets

Performance often depends on finish. That’s why we supply multiple options:

  • Hot Rolled Sheets: Strong & economical for heavy-duty use.
  • Cold Rolled Sheets: Smooth finish, tighter tolerances.
  • Polished Sheets: For precision applications.
  • 2B & BA (Bright Annealed) Finish: Ideal for chemical & aerospace industries.

Combined with its natural resistance to chlorides, seawater, and aggressive acids, Inconel 625 sheets offer longer service life compared to stainless steels.

Fabrication, Machining & Welding Guidelines for Alloy 625 Sheets

Engineers often worry: “Can this material be fabricated easily?”
Inconel 625 sheets are known for their excellent workability:

  • Machining: Best in annealed condition with carbide tools.
  • Welding: Suitable for GTAW, GMAW, SMAW without cracking.
  • Formability: Hot/cold workable, rollable into complex shapes.
  • Heat Treatment: Solution annealing at 1150°C restores full corrosion resistance.

With our guidance and datasheets, fabrication becomes faster, safer, and more cost-efficient.
