Welding and Fabrication Tips
- Welding: Use GTAW (TIG) or GMAW (MIG) with ERNiCrMo-3 filler; no post-weld heat treatment needed.
- Forging: Heat to 1010-1150°C (1850-2102°F); avoid below 954°C (1750°F).
- Machining: Annealed state preferred; use rigid tools for Inconel 625 high nickel alloy round bars.

Frequently Asked Questions
Q1: How does Inconel 625 compare to Inconel 718?
A: Inconel 625 excels in corrosion resistance across a wide temp range (-196°C to 982°C), while 718 offers higher strength (up to 1375 MPa) at elevated heat due to aging. Pick 625 for corrosion, 718 for extreme strength.
Q2: What’s the best use for Inconel 625 Nickel Alloy Bar?
A: It’s ideal for harsh, corrosive environments—think aerospace exhausts, marine shafts, or Inconel 625 bar in chemical reactors. Strength and durability shine where others fail.
Q3: Is Inconel 625 stronger than stainless steel?
A: Yes, with tensile strength around 930 MPa vs. 316’s 515 MPa, Inconel 625 outclasses stainless in strength and corrosion resistance, especially at high temps or in acids.
Q4: Can Inconel 625 be welded easily?
A: Absolutely! Use TIG or MIG with ERNiCrMo-3 filler—it welds smoothly with no post-weld heat treatment. Inconel 625 are a fabricator’s dream.
Q5: How does Inconel 625 Bar perform in saltwater?
A: It’s a superstar—resists pitting and crevice corrosion in seawater better than most alloys. inconel 625 bar is a top pick for marine and offshore applications.
