718 is a precipitation-hardening nickel-chromium alloy,as a nickle alloy,which means comprised of at least 50% of nickel,Inconel 718 with nickel 55% max of the final alloy.

Chromium (Cr) is the secondary elements for Inconel 718,with 17.0 – 21.0% in mass.

718 alloy also with Niobium (Nb),tantalum (Ta),iron (Fe),molybdenum (Mo),cobalt (Co), aluminum (Al), titanium (Ti) Metal elements

Non-metal elements silicon (Si),C,S,P also found in Inconel 718.

All of these elements are used to enhance specific traits and charactors to Inconel 718. 

Chromium offers great corrosion resistance to water,acid and other natural elements. The use of niobium and tantalum with enhanced mechanical properties.molybdenum in both resistance to corrosion and overall alloy strength,but also helps make Inconel 718 more suitable for welding.

2.Accordingly 718 alloy products follow the design and standard

For example,alloy 718 bars,diameter,diameter tolerance,range of length with tolerance,surface requirements,hardness of 718,and machinical properties such as TS,YS,etc

3.Alloy 718 is non-magnetic

It maintains good corrosion resistance and oxidation resistance and is used for parts requiring high resistance to creep and stress rupture up to 1300°F (704°C) and oxidation resistance up to 1800°F (982°C)

4.applications of alloy 718

usually made parts of Jet engine,Gas turbine operations,Base plates,Rotor bolts in Power generation,discs
