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.
Chemical Composition (%):
Inconel 718 Physical Property
Good process property
Good welding performance
Stable chemical property in low temperature
High tensil strength ,fatigue resistance,creep strength, breaking strenght
Good corrosion resistance
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 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.
Packing and Shipping
We both have a manufactory and trade company, our company is specialized in making high quality high speed steels, M2, M35, M42, W9, W18 and some mould steels , maraging steels, permalloy steel. Our products have exported to many countries like Russia, Germany, Netherlands, Hungary, Vietnam, Italy etc. and we received many good feedback.
If you are interested in our products, please send us inquiries and contact us freely, hope we can get a further cooperation!
A: T/T 30% for down payment, Then T/T balance on the actual weight of ready for shipment products on the basis of the Seller's account.
2 Q: How to ensure your products is qualified?
A: The Quantity and weight of product are certified by the seller’s Inspection Certificate and the quality is certified by the Mill Taste Certificate agreed form.
3 Q: How to confirm the Acceptance of Goods and Quality Control?
A: Once the manufacturing of a batch is complete, two samples will be acquired at random by the buyer’s representatives for testing at independent labs. One sample will be sent to a lab in Seller’s country and the other sample to a lab in buyer’s country.
