Product Details
Special Metals Inconel 718 Bar Nickel Alloy 718 with Ending
Machinability
Composition and Properties:
Inconel 718 is a nickel-chromium alloy that is precipitation
hardenable due to significant levels of iron, niobium, and
molybdenum, along with lesser amounts of aluminum and titanium.
This composition provides a high degree of tensile, fatigue, creep,
and rupture strength, coupled with excellent corrosion resistance
in a range of environments.
Mechanical Characteristics:
With a melting point around 1260-1340°C (2300-2440°F), Inconel 718
offers resistivity against post-weld cracking and has the ability
to maintain its strength under extreme temperatures, as low as
cryogenic levels and as high as 700°C (1300°F). It has excellent
relaxation resistance and remains ductile and tough.
Manufacturing Specifications:
Inconel 718 bars typically adhere to standards such as ASTM B637,
which governs the alloy's chemical composition and mechanical
properties requirements, as well as its precipitation hardening
process.
Applications:
Due to its resilience and reliable performance, Inconel 718 round
bars are often utilized in high-stress applications such as
aerospace engine parts, fasteners, and cryogenic tanks, alongside
components used in oil and gas drilling and wellhead equipment.
Physical Characteristics:
As a high-strength material, Inconel 718 can be magnetic and
exhibits an excellent surface finish when machined. Bars come in a
variety of diameters, which can be custom sized to meet specific
demands.
Availability:
Inconel 718 is widely available and can be procured in custom
lengths with a range of surface finishes tailored for specific
functional requirements, such as bright annealing or age-hardening
treatments to enhance its mechanical properties.
Notable Features:
- High tensile, fatigue, creep, and rupture strength
- Outstanding corrosion resistance
- Superior weldability compared to other Inconel alloys
