Inconel 718 WNr 2.4667 GH4169 nickel round bar

Description of inconel 718

Alloy 718 is a precipitation hardenable nickel-based alloy designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300°F. The sluggish age-hardening response of alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling. This alloy has excellent weldability when compared to the nickel-base superalloys hardened by aluminum and titanium. This alloy has been used for jet engine and high-speed airframe parts such as wheels, buckets, spacers, and high temperature bolts and fasteners.

Processing

Hot working

Proper working temperature 1120-900℃,cooling method is water quenching or other quick cooling method. It must be annealing in time after hot working to maintain best properties. The material should be heat to processing temperature limited when hot working, in order to ensure the material plasticity during processing, when the deformation reaches 20% the final processing temperature should not be lower than 960 ℃.

Cold working

Cold working should be after solution annealing,the rate of hard working is greater than austenitic stainless steel, therefore the equipments need to be adjusted,and there should be solution annealing process during cold processing.
