Product Overview
INCONEL-718-HH Nickel Alloy Wire & Coil is a premium-grade, hot rolled high-temperature forging feedstock engineered for extreme thermal and mechanical demands. This AMS 5596-compliant Inconel 718 wire delivers exceptional strength retention up to 700°C, outstanding oxidation resistance, and superior creep rupture performance—making it the material of choice for mission-critical aerospace, energy, and industrial forging applications. Available in diameters from 4.0mm alloy wire to 12.7mm, each coil is precision-manufactured under strict quality control to ensure dimensional consistency, surface integrity, and metallurgical homogeneity required for seamless hot forging preforms.
As a specialized nickel alloy coil, it features optimized HH (Hot-Hold) chemistry with controlled Nb/Ti ratios and reduced delta phase susceptibility—enabling stable grain structure development during high-strain forging cycles. Its uniform microstructure and low inclusion content minimize forging defects and maximize die life, directly supporting lean, high-yield production workflows.
Key Features
- Full compliance with AMS 5596 specification for Inconel 718 hot-rolled wire
- Optimized HH (Hot-Hold) chemistry for enhanced forgeability and thermal stability
- Consistent surface finish and roundness—ideal for automated feeding and induction heating
- Traceable heat lots with full mill test reports (MTRs) including tensile, hardness, and PMI data
- Available in standard coil weights (100–500 kg) with protective packaging for moisture and handling damage prevention
