Hardened Nickel Base Alloy Forged Round Bar Inconel 718 Plus

Inconel 718 Plus Hardened Nickel-Base Alloy Forged Round Bar

Inconel  718 Plus (UNSN 07818) is a new hardened nickel-base alloy, this alloy is designed to have excellent comprehensive mechanical properties, good heat processing and welding properties,  and appropriate cost below 700°C . The launch of the 718plus alloy effectively fills the long-standing gap between the two most widely used High-temperature alloys Inconel 718 (650 °C) and Waspaloy (750 °C).

Inconel 718 is designed to resist a wide range of severely corrosive environments, pitting and crevice corrosion. This nickel steel alloy also displays exceptionally high yield, tensile, and creep-rupture properties at high temperatures.

Character

 Good mechanical properties – tensile, fatigue and creep-rupture

Yield tensile strength, creep, and rupture strength properties are exceedingly high

Highly resistant to chloride and sulfide stress corrosion cracking

Resistant to aqueous corrosion and chloride ion stress corrosion cracking

High temperature resistant

 Age-hardenable with a unique property of slow aging response that permits heating and cooling during annealing without the danger of cracking.

Excellent welding characteristics, resistant to postweld age cracking

Application
