As a leading supplier and manufacturer in China, GNEE Steel provides cost-effective nickel-based alloy products.

Product Introduction

UNS N07718 is a nickel-chromium alloy being precipitation hardenable and having high creep-rupture strength at high temperatures to about 1300 °F (700 °C). The poor age-hardening response of alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling. This alloy has excellent weldability compared to the nickel-base super alloys hardened by Aluminum and Titanium.
