Welding and Fabrication Tips
- Welding: Use GTAW (TIG) or GMAW (MIG) with Inconel 625 filler; no post-weld anneal needed.
- Forming: Hot-work at 1600-2200°F (871-1204°C); avoid 1200-1600°F range.
- Machining: Annealed state preferred; use sharp tools for Inconel 800 nickel alloy plate rolling.
Our factory ensures fabrication success.
Customer Reviews
Frequently Asked Questions
Q1: How does Inconel 800 compare to Inconel 600?
A: Inconel 800 has higher iron and added titanium/aluminum, boosting carburization and oxidation resistance at high temps (up to 1100°C) compared to 600, which excels in pure corrosion but lacks the same heat durability.
Q2: What’s the best use for Inconel 800 Nickel Alloy Plates?
A: Perfect for high-heat, oxidizing environments—think petrochemical reformers, heat exchangers, or Incoloy 800 plate in furnace muffles. It’s built for where thermal stability and moderate corrosion resistance matter.
Q3: Is Inconel 800 resistant to corrosion in acids?
A: It’s good against nitric and organic acids but struggles with sulfuric or hydrochloric in high concentrations. Inconel 800 shines more in oxidation and aqueous chloride resistance than reducing acids.
Q4: Can Inconel 800 Alloy Plate be welded easily?
A: Yes! Use TIG or MIG with Inconel 625 filler—it welds smoothly without post-weld annealing. Inconel 800 nickel alloy plate rolling and welding make it a fabricator’s friend for complex assemblies.
Q5: How does Inconel 800 Alloy Plate perform at high temperatures?
A: It’s a champ up to 1100°C (2012°F), resisting oxidation and carburization. Avoid the 538-760°C range long-term to prevent carbide precipitation—otherwise, Inconel 800 Alloy Plate is a heat warrior.
