inconel 718/UNS NO7718/W.Nr2.4668 Tubes/Pipes

1. Product Detail

Inconel 718 is a nickel-chromium-molybdenum alloy

1.1 The characteristics of Inconel 718:

(1) Good mechanical properties – tensile, fatigue and creep-rupture

(2) Yield tensile strength, creep, and rupture strength properties are exceedingly high

(3) Highly resistant to chloride and sulfide stress corrosion cracking

(4) Resistant to aqueous corrosion and chloride ion stress corrosion cracking

(5) High temperature resistant

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

(7) Excellent welding characteristics, resistant to post weld age cracking

1.2 The applications of Inconel 718:

(1) Chemical processing

(2) Aerospace

(3) Liquid fuel rocket motor components

(4) Pollution-control equipment

(5) Nuclear reactors

(6) Cryogenic storage tanks

(7) Valves, fasteners, springs, mandrels, tubing hangers

(8) Well head completion equipment and blow out preventers (BOP’s)

(9) Gas turbine engine parts
