Wire mesh belts are widely used in high-temperature applications such as furnaces, heat treatment, drying, and food processing. Their resistance to high temperatures depends on several factors, including material composition, weave type, and operating conditions. Here’s a detailed breakdown:
1. Material Selection for High-Temperature Resistance
The choice of wire material is critical for high-temperature performance. Common options include:
– Stainless Steel (SS) Grades:
– SS 304: Good up to 870°C (1600°F) for intermittent use; resists oxidation but may warp at higher temps.
– SS 310/314: Superior heat resistance (up to 1150°C / 2100°F) due to higher nickel and chromium content.
– SS 316: Resists corrosion but has lower heat tolerance (~800°C / 1472°F).
– High-Nickel Alloys (Inconel®, Hastelloy®):
– Withstand 1200–1300°C (2200–2400°F), ideal for extreme conditions (e.g., aerospace, chemical processing).
– Titanium & Special Alloys:

ions where corrosion resistance and heat stability are paramount.
2. Weave Pattern & Belt Design
– Balanced Weave: Even tension distribution improves longevity under thermal stress.
– Rod-Reinforced Edges: Prevents sagging at high temps.
– Open vs. Closed Mesh: Open designs reduce heat retention; closed meshes offer better support for small parts.
3. Key Factors Affecting Performance
– Thermal Expansion: Metals expand when heated; proper belt tensioning compensates for this.
– Oxidation & Scaling: High temps accelerate oxidation; alloys with chromium (e.g., SS 310) form protective oxide layers.
– Load Capacity: Heavier loads may reduce max operating temperature due to stress.
