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

Incoloy 800 (Nickel-Iron-Chromium superalloy) straight wire is a premier structural material optimized for high-temperature thermal processing environments. Manufactured via vacuum induction melting followed by continuous protective atmosphere bright annealing, each wire length from 1.0mm to 8.0mm features a scale-free, mirror-like metallic luster, exceptional ductility for automated forming, and minimal internal stress. It maintains long-term structural integrity in carburizing, oxidizing, and nitriding atmospheres.

Incoloy 800 is formulated to resist high-temperature corrosion while retaining ductile mechanical properties during extended exposure to elevated temperatures. Below is the comprehensive technical parameter baseline:

The synergistic combination of 30–35% Nickel and 19–23% Chromium forms a dense, self-healing chromium oxide (Cr2O3) surface barrier. This barrier strongly resists protective atmosphere degradation, carbon uptake in heat-treating furnaces, and internal scaling during continuous thermal cycling.

Processed in continuous hydrogen-protective atmosphere furnaces, our Incoloy 800 wire exhibits zero surface decarburization, completely clean metallic luster, and uniform grain refinement. The resulting low work-hardening rate ensures smooth feeding into automated spiral and rod-reinforced mesh belt weaving machinery without tool wear or wire jamming.

Utilizing multi-axis rotary mechanical straighteners and automated optical sensors, every straight wire achieves an exceptional straightness within ≤0.5 mm/m. Burr-free cut ends prevent snagging during high-speed mesh assembly and cross-rod resistance welding.

With balanced aluminum and titanium content, the alloy matrix resists grain boundary embrittlement and thermal shock during rapid furnace heating and cooling cycles, eliminating premature belt elongation and cross-rod warping.

Primary structural cross-rods, connecting pins, and spiral wire elements for continuous conveyor belts operating in carburizing, hardening, carbonitriding, and sintering furnaces.

Carrying elements and driving cross-rods for high-temperature sintering lines handling heavy mechanical parts under aggressive reducing atmospheres.

Furnace mesh belts for stainless steel and copper brazing lines, as well as glass tempering and ceramic firing tunnels requiring non-scaling wire surfaces.

Internal structural support frames, guide pins, and high-temperature thermal fixtures exposed to direct radiant heating up to 1000°C.

Changzhou DLX is a premier B2B manufacturer specializing in high-performance nickel and specialty alloy wire, strip, and precision components. Operating advanced vacuum melting, hot rolling, cold drawing, and continuous bright annealing production lines, we maintain a reliable global production capacity of 1,200 tons per month.

• Rigorous In-House Testing: Every production lot undergoes spectrometer chemical composition analysis, eddy current surface flaw detection, laser dimensional tolerance verification, and microstructural grain size inspection.
• Engineered Customization: Custom wire diameters (1.0mm to 8.0mm), specified tensile hardness windows, and tailored cut lengths from 500mm to 6 meters.
• Export Packaging Integrity: Moisture-proof vacuum wrapping, rigid PVC protective tubing, and reinforced fumigated wooden crates ensure straight wire arrives with zero transit bending or surface scratching.

A: Unlike standard austenitic stainless steels that suffer from rapid oxidation, sigma phase embrittlement, and excessive creep elongation above 700°C, Incoloy 800 retains high creep-rupture strength, ductility, and structural stability in operating temperatures up to 1000°C. Its high nickel content prevents chloride stress-corrosion cracking and carburization in heat-treatment atmospheres.

A: Each batch is processed through continuous rotary precision straightening units paired with real-time laser alignment systems, ensuring straightness deviation within ≤0.5 mm/m. Continuous bright annealing in protective gas delivers an ultra-smooth, oxide-free surface (Ra ≤0.4 μm) ready for immediate welding and automated weaving.

A: As a dedicated B2B manufacturer, our MOQ is dynamically configured based on diameter specifications and customized cut-length requirements. Standard sizes typically ship within 7–15 working days, while customized dimensional tolerances or specific mechanical profiles are fulfilled under streamlined mill scheduling.

A: Yes. Due to high elemental purity and low impurity content, our Incoloy 800 wire exhibits outstanding weldability via TIG, MIG, and resistance welding without post-weld heat treatment, creating robust joint integrity under continuous cyclic thermal loads.
