Inconel 718, a nickel-chromium superalloy, delivers unmatched strength and corrosion resistance for critical applications. Its optimized chemistry includes:
- Ni (50–55%): Ensures exceptional high-temperature stability and oxidation resistance12.
- Cr (17–21%): Enhances corrosion resistance through robust oxide layer formation12.
- Nb (4.75–5.5%) & Mo (2.8–3.3%): Strengthen alloy via precipitation hardening and chloride resistance12.
Advanced Machining & Fabrication Capabilities
Inconel 718 round bars are precision-engineered for demanding manufacturing processes:
- Machining: Achieve superior surface finishes with ceramic or carbide tools at 15–20 m/min cutting speeds. High-pressure coolant (100+ bar) minimizes tool wear14.
- Welding: Compatible with TIG, plasma arc, and electron beam methods. Post-weld heat treatment restores full strength14.
- Heat Treatment: Optimize performance via solution annealing (950–1,050°C) and aging (720°C) for peak hardness (HRC 34–39)24.
Mission-Critical Applications Across Industries
Inconel 718 round bars power innovation in extreme conditions:
- Aerospace: Turbine blades, combustion chambers, and compressor disks (withstands 1,000°C)14.
- Oil & Gas: Downhole tools, valves, and pump shafts resistant to H2S and chloride stress corrosion14.
- Nuclear Energy: Reactor core components and fuel cladding with neutron irradiation stability12.
- Medical: Surgical instruments requiring biocompatibility and sterilization durability45.
