Inconel 718 is a high-strength, corrosion-resistant nickel-chromium alloy designed for excellent tensile, impact, and fatigue strength at temperatures up to 704°C (1300°F). This precipitation-hardenable material is particularly suitable for extreme environments and finds applications across aerospace, marine, chemical processing, and nuclear sectors.
As a trusted supplier, Dengwei Steel offers premium Inconel 718 round bars with precision manufacturing, rigorous quality control, and tailored processing services. Whether you're prototyping or scaling industrial production, we provide a complete solution with rapid delivery and documentation support.
Maintains high mechanical strength at elevated temperatures
Excellent resistance to pitting, crevice corrosion, and stress-corrosion cracking
Good weldability with minimal cracking risk
Prolonged service life in oxidizing and corrosive atmospheres
High fatigue strength and stress rupture resistance

Fast global delivery from multiple stock locations
Flexible MOQ, OEM/ODM capability
Technical consultation and custom sourcing
100% quality assurance and refund guarantee
Inconel 718 has higher strength due to age hardening and is better suited for high-load structural parts. Inconel 625 offers better corrosion resistance but lower mechanical strength.
Yes, we support third-party inspections by SGS, BV, TUV, and others upon request.
Yes, small samples are available for quality evaluation. Shipping charges may apply.
Generally 5–10 working days for stock items; 15–25 days for production orders.
Yes, we offer CNC turning, drilling, threading, and surface finishing based on your drawings or specs.
Each bar is packed in protective wrapping with ends capped, bundled in wooden crates suitable for export shipping.
Absolutely. Each batch is marked with heat number and comes with a full material traceability certificate.
We accept T/T, L/C, PayPal, and Western Union. Flexible terms for long-term partners.
