Bright Annealed Straight Wire Incoloy 800 Dia 1.0-8.0mm for High Temp Mesh Belts

In demanding thermal processing operations—such as powder metallurgy sintering, continuous brazing, and heat treatment lines—conveyor mesh belts endure extreme thermal cycling, heavy mechanical loads, and aggressive furnace atmospheres. Conventional heat-resistant wires often suffer from embrittlement, surface scaling, or premature sagging.

Our bright annealed Incoloy 800 straight wire is metallurgically balanced to maintain a fully stable austenitic structure across prolonged high-temperature exposure. By implementing advanced Vacuum Induction Melting (VIM) followed by Electroslag Remelting (ESR), we achieve ultra-low residual gas content and tightly controlled micro-alloying elements (Aluminum and Titanium).

Following precision drawing, each wire undergoes pure hydrogen protective bright annealing to yield a lustrous, scale-free surface that eliminates the need for post-processing acid pickling. Precision online multi-roll straightening technology ensures ultra-tight camber and straightness tolerances, allowing high-speed automated spiral winding, cross-rod assembly, and chain link fabrication without jamming or uneven pitch.

• Superior High-Temperature Oxidation & Carburization Resistance

With a balanced 30–35% Nickel and 19–23% Chromium matrix, bright annealed Incoloy 800 straight wire forms a continuous, self-healing chromium-aluminum-titanium oxide protective layer. It effectively resists scaling, internal oxidation, and carburization under continuous and cyclic thermal operations up to 1100°C.

• Exceptional Creep Rupture Strength & Microstructural Stability  

Maintains excellent mechanical integrity and structural ductileness without transforming into brittle phases during long-term exposure in the critical 550°C–800°C temperature zone, preventing mesh belt distortion and elongation.

• Flawless Bright Annealed Surface & High-Precision Linearity 

Processed under 100% dry hydrogen protective atmosphere, providing an ultra-smooth, mirror-like finish free of scratches, burrs, and oxide contamination. Precision straightening ensures minimum camber deviation (< 0.5 mm/m), ideal for robotic mesh belt assembly.

• Consistent Elongation & Uniform Formability 

Narrow tensile strength tolerances and homogeneous grain structure across each batch ensure consistent springback and zero micro-cracking during tight-radius spiral looping and cold knuckling.

• Industrial Heat Treatment Furnace Conveyor Belts 

Ideal for balanced-weave, double-balanced, and compound-balanced mesh belts running in continuous annealing, carburizing, hardening, and quenching furnaces.

• Powder Metallurgy & Sintering Lines

Serves as heavy-duty transverse connecting rods and longitudinal spiral wires for sintering belts operating under protective cracked ammonia and endothermic gas atmospheres.

• High-Temperature Brazing & Glass Annealing Lehrs 

 Provides long-lasting durability for continuous conveyor grids in copper brazing, silver soldering, and glass annealing lehrs.

• Custom Thermal Fixtures & Heating Element Supports 

 Straightened wire rods utilized for furnace support pins, hanging racks, resistance coil tie-downs, and industrial burner internal grids.

• Integrated VIM + ESR Refining Infrastructure 

We control every stage of alloy manufacturing—from raw material selection, vacuum induction melting (VIM), and electroslag remelting (ESR) to hot rolling, multi-pass cold drawing, and continuous hydrogen bright annealing.

• 1,200 Tons/Month Comprehensive Capacity 

Equipped with high-speed multi-head drawing lines and automated CNC cutting units, our monthly manufacturing capacity reaches 1,200 tons, ensuring reliable delivery for both project-based and volume contract orders.

• 100% Quality Verification & Traceable Testing 

Each batch undergoes strict spectrographic chemical analysis, eddy current surface flaw detection, laser micrometer diameter inspection, and reverse bending ductility tests before packing. Full metallurgical test certificates are delivered with each shipment.

• Engineered Customization for Mesh Belt Builders 

We supply tailored diameters, specific mechanical temper windows (annealed, quarter-hard, or spring temper), and customized straight cut lengths packed in secure wooden crates or rigid fiberboard tubes.
