Introduction

Inconel 625 Plate (also Inconel 625 Sheet, Alloy 625 Plate, Nickel Alloy 625 Plate, UNS N06625 Plate, High Strength Nickel Alloy Plate, Corrosion Resistant Nickel Alloy Sheet) is a nickel‑chromium‑molybdenum‑niobium alloy offering an outstanding combination of high strength, exceptional seawater corrosion resistance, and excellent fabricability. It conforms to ASTM B443, ASME SB443, AMS 5599 (sheet), AMS 5666, and AMS 5837 (plate). This aerospace grade nickel alloy plate is designated UNS N06625 and W.Nr. 2.4856, widely used in offshore platforms, heat exchangers, gas turbines, and marine engineering where both strength and corrosion resistance are critical.

Key properties of Inconel 625 Plate:

• Exceptional seawater corrosion resistance – immune to pitting, crevice corrosion, and stress corrosion cracking in chloride‑containing marine environments

• High strength nickel alloy plate – excellent tensile and creep‑rupture strength up to 980°C (1800°F)

• Superior fatigue resistance – withstands cyclic loads from waves, vibrations, and pressure fluctuations

• Chloride resistant alloy sheet – outperforms stainless steel and many other alloys in high‑chloride, low‑pH conditions

• Pitting and crevice corrosion resistant plate – no localized attack, even under marine deposits or biofouling

• Excellent weldability nickel alloy – can be welded without post‑weld heat treatment using matching filler metal (ERNiCrMo‑3)

• High temperature oxidation resistance – stable protective oxide layer up to 980°C

• Stress corrosion cracking resistance – immune to chloride‑induced SCC, suitable for sour service and marine environments

• Outstanding strength to weight ratio – ideal for lightweight structural components in aerospace and offshore applications

Note: Inconel 625 Plate is the preferred material for heat exchanger tube sheets, offshore structural plates, aerospace engine components, and pressure vessel shells where a combination of strength, corrosion resistance, and weldability is required.

This industrial alloy plate is available in plate (hot rolled), sheet (cold rolled), and coil forms, with pickled, polished, and precision ground surface finishes. We offer custom sizes, cut to size, thick plate, and fabricated sheet services. Our product range includes Inconel 625 Plate, Sheet, Coil, thick plate, custom size, and cut to size plate.

Applications

1. Offshore Structures & Marine Engineering

• Inconel 625 plate for offshore structures – topside support plates, riser clamp components, and structural stiffeners on fixed platforms, FPSOs, and floating wind turbines. High strength nickel alloy plate provides long‑term integrity in saltwater splash zones and submerged conditions.

• Inconel 625 plate for marine engineering – boat hull reinforcement plates, deck machinery bases, and cryogenic pipe support plates for LNG carriers. Seawater corrosion resistance eliminates painting and sacrificial anodes.

• Offshore grade alloy plate – also used in subsea manifold skids, mudline suspension plates, and subsea structural nodes.

2. Heat Exchangers & Pressure Vessels

• Inconel 625 plate for heat exchangers – tube sheets, baffle plates, and channel covers for shell‑and‑tube heat exchangers in marine cooling systems, chemical plants, and LNG facilities. Chloride resistant alloy sheet prevents tube‑to‑tubesheet crevice corrosion.

• Inconel 625 plate for pressure vessels – ASME Code stamped vessel shells, heads, and nozzle pads for high‑pressure, corrosive service (seawater, chlorides, acids). Pitting resistant plate ensures safe operation.

• Heat exchanger plate material – also used in plate‑and‑frame heat exchangers for desalination and offshore platforms.

3. Aerospace Components & Gas Turbine Parts

• Inconel 625 sheet for aerospace components – engine nacelle skins, afterburner liners, and exhaust nozzle components in commercial and military aircraft. High temperature oxidation resistance up to 980°C and fatigue resistance under thermal cycling.

• Inconel 625 plate for gas turbine parts – combustor casing plates, turbine shroud support rings, and transition duct panels in industrial and marine gas turbines. High strength alloy sheet withstands high‑velocity hot gas erosion.

• Aerospace grade nickel alloy plate – also used in rocket engine thrust chambers, heat shields, and cryogenic tank support structures.

4. LNG Facilities & Desalination Plants

• Inconel 625 sheet for LNG facilities – cold box support plates, pipe flange covers, and modular skid base plates for liquefaction trains. Crevice corrosion resistant alloy performs at cryogenic temperatures (−162°C).

• Inconel 625 plate for desalination plants – evaporator shell plates, brine heater tube sheets, and high‑pressure pump base plates in MSF and RO plants. Outstanding strength to weight ratio reduces equipment weight.

5. Exhaust Systems & Power Generation

• Inconel 625 sheet for exhaust systems – marine engine exhaust gas silencer plates, gas turbine exhaust diffusers, and boiler furnace wall panels. High temperature oxidation resistance and thermal fatigue resistance.

• Inconel 625 sheet for power generation equipment – flue gas desulfurization (FGD) absorber tower liners, stack inlet duct plates, and scrubber support grids. Corrosion resistant nickel alloy plate handles low‑pH, high‑chloride scrubber liquor.
