Precipitation Hardened Nickel-base Superalloy

ATI 718Plus® alloy is a precipitation hardened nickel-base superalloy that exhibits a combination of superior high temperature properties and good fabricability. This alloy is designed to have the high temperature capability and thermal stability of Waspaloy* alloy while retaining the processing characteristics of 718 alloy. It is produced by double vacuum melting (VIM/VAR) or triple melting (VIM/ESR/VAR), depending on the application. The VIM/VAR process ensures excellent micro-cleanliness and tight compositional control. Triple melting further minimizes macrosegregation, increases microcleanliness, and is preferred for premium quality jet engine rotating components. 718Plus alloy provides a nominal 100 F° (55 C°) operating temperature advantage over 718 alloy and has higher strength, superior formability, better wear resistance, and resistance to weld cracking advantages over Waspaloy and other, higher temperature nickel-base alloys. Since 718Plus alloy has a lower intrinsic raw material cost than Waspaloy alloy, and also has improved hot workability with resulting higher material yield, lower finished part costs can be achieved. 718Plus alloy is available in all product forms including: ingot, billet, forged round and rectangular bar, hot-rolled shapes and rectangles, round bar, rod, wire, plate, sheet, strip, and castings.
