Basic Information Of Inconel 625 Product

The following is the product specifications of Inconel alloy 625. If you need other more information, please contact us.

What are the features of Inconel 625?

Inconel 625 is a high temperature alloy known for its excellent corrosion resistance.

Excellent corrosion resistance

Excellent corrosion resistance

  • It exhibits excellent resistance to general corrosion, pitting, crevice corrosion and stress corrosion cracking in a wide range of corrosive environments
  • We ensure that the Inconel 625 material we provide meets the corrosion resistance level required by the specification and meets the needs of complex working conditions by precisely controlling the alloy composition and adopting standard solid solution annealing heat treatment processes.

Excellent combination of high temperature strength

  • The alloy can maintain high strength and good creep resistance from low temperature to medium and high temperature1112°F – 1652°F (about 600°C to 900°C)
  • We strictly follow the material production and processing specifications to ensure that the material obtains a uniform microstructure in the solution treatment state, thereby ensuring the structural integrity of the component at the service temperature.

Gas turbine blades
TIG welding

Good processing and welding performance

  • Inconel 625 has relatively good cold and hot forming ability and weldability. It can be welded by conventional methods, and usually does not require post-weld heat treatment after welding to obtain good corrosion resistance
  • We have mature experience in Inconel 625 material processing and welding processes, and can provide customers with semi-finished or finished parts that meet specification requirements.

FAQ

Below are some frequently asked questions about Inconel Alloy 625. If you have any other questions, please feel free to contact us.

No, Inconel 625 is a non-magnetic material.
Its matrix is ​​an austenitic nickel-chromium structure (nickel ≥ 58%, chromium 20-23%), with no ferromagnetic phase transition

Hardness range:

Annealed state: Brinell hardness HB 170-220
Solution state: Brinell hardness HB 220-250
Cold worked state: Rockwell hardness HRB 90-100

Yes, but the purpose and method are different from precipitation hardening alloys.

Heat treatment types: solution treatment, stabilization treatment, stress relief

No, it is a nickel-based superalloy.

The core difference lies in the nickel content: 625 contains ≥58% nickel, which is much higher than stainless steel (usually <36%);

Surface treatment
→ Use acetone to thoroughly clean the groove, remove oil and oxide layer
Method selection
→ TIG welding (inert gas protection) is preferred, and MIG welding can be used for thick plates

Parameter control
→ Low heat input: lower current and voltage, increase speed
→ Layer temperature: ≤150°C

Welding material matching
→ Use ERNiCrMo-3 welding wire (composition consistent with base material)
