Nickel-Based Alloy Products We Supply

Our nickel-based alloys are available in multiple product forms to support different manufacturing and engineering needs.

Nickel Alloy Bars and Rods

Nickel alloy bars are commonly used to machine precision parts such as shafts, valve components, fasteners, and high-temperature structural parts. Their excellent strength and thermal stability make them suitable for demanding operating environments.

Nickel Alloy Plates and Sheets

Nickel alloy plates are widely used in pressure vessels, heat exchangers, and chemical processing equipment. These plates offer outstanding resistance to corrosion and oxidation.

Nickel Alloy Forgings

Nickel alloy forgings are used when components require high structural integrity and mechanical strength. Typical forged products include forged rings, flanges, discs, shafts, and custom heavy-duty components.

Nickel Alloy Tubes and Pipes

Nickel alloy tubes are frequently used in high-temperature pipelines, heat exchangers, and chemical transport systems where durability and corrosion resistance are required.

Custom Nickel Alloy Components

We also manufacture customized nickel alloy parts according to customer drawings. These components can be produced through forging, machining, or other specialized processes depending on the application.

Why Choose Our Nickel-Based Alloys

Nickel alloys are often selected for applications where material failure is not acceptable. Our materials are processed with strict quality control to ensure consistent performance.

Instructions

1

Excellent High Temperature Resistance

Nickel-based alloys retain their strength and stability at temperatures where many other metals begin to weaken. This makes them ideal for turbines, aerospace systems, and heat processing equipment.

Excellent High Temperature Resistance
2

Strong Corrosion and Oxidation Resistance

Nickel alloys perform well in environments exposed to acids, alkalis, seawater, and high humidity. Their resistance to corrosion significantly extends the service life of equipment.

Strong Corrosion and Oxidation Resistance
3

Reliable Mechanical Properties

Nickel alloys offer excellent creep resistance, fatigue strength, and toughness. These characteristics help prevent deformation and cracking during long-term operation.

Common Nickel-Based Alloy Grades

Nickel-based alloys are engineered materials designed to perform in environments where high temperature, corrosion, and mechanical stress are present. Compared with conventional stainless steels, nickel alloys provide superior resistance to oxidation, chemical corrosion, and creep deformation at elevated temperatures.

The following grades are widely used across multiple industries.

1. Inconel Series (Nickel-Chromium Based Heat-Resistant Alloys)

Used primarily in high-temperature and oxidation-resistant environments such as aircraft engines and nuclear reactors.

  • ‌Inconel 600‌ (GH3600): Ni-Cr-Fe solid-solution strengthened alloy with excellent oxidation resistance; suitable for thermocouple sheaths and chemical equipment.
  • Inconel 625‌ (GH3625): Ni-Cr-Mo-Nb alloy with molybdenum and niobium; highly resistant to chloride corrosion; widely used in marine engineering and acidic oil/gas environments.
  • Inconel 718‌ (GH4169): Precipitation-hardened with γ” and γ’ phases; high strength; core material for turbine disks and blades in aviation engines.
  • Inconel X-750‌ (GH4145): γ’-phase strengthened; used in high-temperature springs and turbine blades; excellent stress relaxation resistance below 540°C.

2. Incoloy Series (Iron-Nickel-Chromium Based Corrosion-Resistant Alloys)

Lower cost, suitable for moderate-temperature corrosion-resistant applications such as petrochemical and boiler systems.

  • Incoloy 800H‌ (NO8810 / NS112): Fe-Ni-Cr alloy with moderate (Al+Ti) content; excellent tensile strength and toughness between 600–700°C.
  • Incoloy 825‌ (NS142): Ni-Cr-Mo-Cu alloy; resistant to sulfuric and phosphoric acids; commonly used in acid processing equipment.
  • Incoloy A-286‌ (GH2132): Fe-Ni-Cr base precipitation-hardening alloy with added Ti, Al, and Mo; used in high-strength components below 650°C, such as fasteners.

3. Monel Series (Nickel-Copper Alloys)

Suitable for reducing media, especially resistant to hydrofluoric acid and seawater corrosion.

  • Monel 400‌ (Ni65Cu30): Excellent corrosion resistance in oxygen-free fluoride environments; used in marine engineering and chemical pumps.
  • Monel K500‌: Based on Monel 400 with added Al and Ti for precipitation strengthening; higher strength but more susceptible to stress corrosion cracking.

4. Hastelloy Series (Nickel-Molybdenum/Chromium-Molybdenum Alloys)

Designed specifically for extreme corrosive environments.

  • Hastelloy B-2/B-3‌ (N10665/N10675): Ni-Mo alloys with excellent resistance to non-oxidizing acids like hydrochloric and sulfuric acid.
  • Hastelloy C-276/C-22‌ (N10276/N06022): Ni-Cr-Mo-W alloys; resistant to mixed oxidizing and reducing environments; widely used in environmental protection and petrochemical industries.

5. Domestic Chinese Grades (GH / K / NS Series)

Classification under Chinese standards, with clear differentiation by application.

  • GH4169‌: Equivalent to Inconel 718; a primary material in domestic aerospace applications.
  • GH4145‌: Equivalent to Inconel X-750; used in high-temperature springs and fasteners.
  • GH2132‌: Equivalent to Incoloy A-286; good thermal strength.
  • K417‌: Cast nickel-based superalloy used in complex cast parts such as turbine guide vanes.
  • NS3103 / NS313‌: Equivalent to Inconel 601; excellent high-temperature oxidation resistance.

6. Other Common Grades

  • Inconel 601‌ (NS3103): High aluminum content provides superior oxidation resistance; suitable for heat treatment furnace tubes.
  • Alloy 20 / RA330‌: Though iron-nickel based, they fall within the application scope of nickel-based alloys; resistant to sulfuric acid and high-temperature thermal cycling, respectively.
