Nickel alloy Inconel® 718 (UNS N07718, DIN 2.4375) yog siv dav siv nickel-based alloy nrog ntau cov ntsiab lus alloying ntxiv.
Raws li nickel-raws li alloy, nws zoo li tsis muaj hlau nplaum. Txawm hais tias nws yuav muaj txog li 20% hlau los ntawm qhov hnyav, cov neeg feem coob yuav xav tias nws yog cov hlau tsis muaj hlau thiab piav qhia tias nws yog superalloy vim nws cov khoom ntawm qhov kub siab.
Inconel 718 khaws cia feem ntau ntawm nws cov khoom siv kho tshuab ntawm qhov kub txog 650 degrees Celsius (1200 degrees Fahrenheit), txawm hais tias nws tiv thaiv oxidation ntawm qhov kub siab dua.
Nickel-raws li alloys xws li Inconel 718 yuav ua hauj lwm nyuaj thaum lub sij hawm machining, drilling, thiab fabrication. Muab hais tias nws twb yog ib tug high-zog alloy thaum muab nyob rau hauv lub hnub nyoog mob, ceev xaiv cov cuab yeej, coolants, thiab CNC tshuab chaw yuav tsum tau.
Inconel 718 tuaj yeem welded tau yooj yim, thiab yog tias welded rau nws tus kheej, feem ntau siv cov khoom siv hlau sib txuam.
Sib piv Inconel 718 rau Inconel 625, Inconel 625 muaj cov ntsiab lus siab dua, yog li nws tau txhim kho corrosion kuj nyob rau hauv feem ntau ib puag ncig, tab sis nws raug nqi ntau dua. Txawm li cas los xij, Inconel 718 muaj lub zog ntau dua vim muaj kev sib xyaw ua ke ntawm cov khoom siv ntxiv thiab kev kho cua sov uas tso cai rau nws muaj hnub nyoog-hardened.
