Nickel 718, tseem hu ua Inconel 718, yog nag lossis daus-tawv nickel-raws li kub kub alloy nrog siab zog, corrosion kuj thiab zoo vuam zog. Cov alloy no nthuav tawm cov khoom zoo tshaj plaws hauv qhov kub ntawm -253 degree mus rau 700 degree, tshwj xeeb tshaj yog qis dua 650 degree, nws lub zog yield yog thawj zaug ntawm cov hlau deformable high-temperature alloys.
Nickel 718 lub cev muaj zog:
Quav: Txog 8.19 g /M³
Melting taw tes: 1260-1336 degree
Lub peev xwm kub tshwj xeeb: 435 J / (kg·K)
Thermal conductivity: 11.4 w / (map k) (ntawm 20 degree)
Inconel 718 mechanical zog:
Tensile Lub Zog (ulb): 965 MPa
Yield zog (σ0.2): 550 MPa
Elongation (δ): 12-20%
Kev txo qis (ψ): 30-40%
Hardness: Tsawg dua los yog sib npaug rau 331 HB
Inconel Alloy 718 Kev kho cua sov:
Kev kho cua sov ntawm Inconel 718 alloy feem ntau suav nrog kev kho kev daws teeb meem thiab kev laus kho kom tau txais cov khoom zoo tshaj plaws. Cov kauj ruam kev kho cua sov ib txwm muaj xws li:
Kev Kho Mob: Nco ntsoov ntawm 980-1010 degree rau 1 teev, ua raws li los ntawm kev ua kom txias sai.
Kev laus kev kho mob: Thawj kauj ruam yog khaws nws ntawm 720 degree rau 8 teev, ces txias nws mus rau 620 degree ntawm tus nqi ntawm 50 degree / teev; Cov kauj ruam thib ob yog khaws cia ntawm 620 degree rau 8 teev, ces cua txias nws.
Vim nws cov kev ua tau zoo heev, Inconel 718 Alloy tau siv dav hauv cov teb hauv qab no:
Aerospace: siv los tsim cov khoom tseem ceeb xws li tshuab dav hlau, turbine hniav, combustion chambers thiab nozzles.
Zog: siv rau cov ntim khoom, cov kav dej thiab cov khoom siv hauv cov khoom siv hluav taws xob nuclear, nrog rau cua tshuab thiab cov khoom siv hluav taws xob.
Petrochemical: siv los tsim cov kev kub kub thiab kub-siab li qub, kav dej thiab kev hloov cua sov thiab lwm yam khoom siv.
