When operating at extreme furnace temperatures, the right conveyor belt material is critical to ensure long service life, stable production, and reduced downtime. In this guide, we compare 310S stainless steel, 314 stainless steel, and NiCr 2080 alloy to help you select the most reliable solution for your heat treatment system.
Why Material Selection is Critical for Furnace Belts
Conveyor belts in heat treatment, annealing, or sintering furnaces must withstand continuous exposure to:
- Temperatures exceeding 1000°C
- Oxidizing or reducing atmospheres
- Mechanical loads and thermal cycling
Choosing the wrong belt material can lead to:
- Deformation and sagging under high heat
- Oxidation and scale peeling that contaminates products
- Frequent replacements, increasing maintenance costs
The correct choice ensures stable performance, reduced downtime, and cost efficiency.

Key Advantages of NiCr 2080 Alloy Conveyor Belts
✅ Higher Heat Resistance – Continuous operation up to 1200°C
✅ Excellent Oxidation Protection – Stable protective oxide layer prevents scaling
✅ Superior Creep Strength – Maintains stability during long-term exposure
✅ Extended Service Life – Lasts nearly twice as long as stainless steel belts
✅ Cost Efficiency – Fewer replacements and reduced production downtime
Applications of NiCr 2080 Wire Mesh Belts
- NiCr 2080 belts are the preferred choice in:
- Bright annealing furnaces
- Carburizing and nitriding furnaces
- Brazing furnaces
- Powder metallurgy sintering lines
- Continuous heat treatment systems
Customer Case Study
A European powder metallurgy manufacturer previously used 314 stainless steel belts, which lasted about 9 months before replacement. After switching to NiCr 2080 alloy belts, their average belt lifespan nearly doubled to 20 months. This upgrade not only saved them significant replacement costs, but also eliminated product contamination caused by oxide scaling, resulting in higher-quality finished parts.
