Yog inconel 718 tsis sib nqus?
Dab tsi yog lub cev lub cev ntawm inconel 718?
Nickel alloys
Inconel 718 (Tsis yog N07718, DIN 2.4375) yog siv cov npib tsib xee-raws li cov alloy, nrog kev sib ntxiv. Raws li ib npib tsib xee-based alloys nws yog qhov tsis muaj hlau nplaum. Txawm hais tias nws yuav muaj li 20% los ntawm qhov hnyav, feem ntau yuav xav nws kom tsis yog-ferrous thiab piav qhia txog tus account ntawm nws cov khoom kub.
Keeb kwm ntawm inconel 718
Inconel 718 yog Ameslikas tau tsim los siv rau hauv chav fais fab nroj tsuag, tab sis tau dhau los siv dav hauv ib tus account ntawm nws tus kheej mus rau oxidation ntawm ntug dej kub. Txawm li cas los xij, nws npaj txhij, ua ke nrog lub zog siab thiab zoo heev corrosion ua rau nws muaj kev lag luam tsim nyog rau cov roj thiab roj kev lag luam.
Inconel 718 khaws ntau ntawm nws cov khoom siv tau mus txog 650degc (1200degc (txawm hais tias nws yuav tawm tsam oxidation ntawm qhov kub siab dua. Lub ntsiab lus melting ntawm inconel 718 yog nyob rau hauv ntau li {{}} degc ({}} degf).
Nickel-based alloys xws li Innonel 718 yuav ua rau lub sijhawm ua haujlwm thaum lub sijhawm machining, drilling thiab fabrication. Muab hais tias nws yog twb muaj lub siab-zog alloy thaum muab rau kev xaiv muaj hnub nyoog, kev xaiv ua tib zoo saib xyuas yog qhov yuav tsum tau ua. Inconel 718 tuaj yeem npaj tau yooj yim welded, feem ntau nrog ib tug sib phim cov hlau yog tias tau welded rau nws tus kheej.
Inconel 718 vs inconel 625
Sib piv inconel 718 vs. Inconel 625, ces inconel 625 muaj cov ntsiab lus corrosion thiab yog li txhim kho corrosion cov ntsiab lus nyob rau hauv feem ntau cov chaw ib puag ncig, albeit ntawm tus nqi ntau dua. Txawm li cas los xij, Inconel 718 muaj lub zog siab dua, vim muaj kev sib xyaw ua ke thiab kev kho cua sov uas tso cai rau nws rau lub hnub nyoog harden.
