2.4668 khoom yog dab tsi?
Khoom siv 2.4668 yog German (Werkstoff) tsim rau Alloy 718, siab - zog, corrosion-resistant, npib tsib xee-chromium superalloy hu ua Inconel 718 (los yog UNS N07718), dav siv dav hauv aerospace, roj & roj, thiab nws cov khoom zoo heev hauv kev lag luam nuclear. kub thiab qis vim muaj hnub nyoog- hardening ntsiab xws li niobium thiab molybdenum.
yog dab tsi2.4668 cov khoom sib npaug?
Khoom siv 2.4668 yog tus qauv German (Werkstoff) rau Inconel 718 (los yog Alloy 718), siab - zog, corrosion-resistant nickel-chromium superalloy siv nyob rau hauv aerospace, roj & roj, thiab cryogenics, kuj paub los ntawm nws UNS tus naj npawb N07718, thiab deformation. NiCr19Fe19Nb5Mo3. Nws yog lub npe hu rau weldability zoo heev, lub zog ntawm qhov kub thiab txias, thiab tiv thaiv kev ntxhov siab -corrosion cracking, feem ntau siv rau fasteners, turbine qhov chaw, thiab foob pob ua ntxaij.

Cov khoom ntawm 2.4668 yog dab tsi?
2.4668) yog ib qho siab -lub zog, corrosion- cov khoom siv nickel chromium resistant siv ntawm -423℃rau 1300℃F. Cov kev txwv tsis pub muaj nyob rau hauv Table 1. Lub hnub nyoog-hardenable alloy tuaj yeem tsim tau yooj yim, txawm tias mus rau hauv qhov nyuaj. Nws cov yam ntxwv welding, tshwj xeeb tshaj yog nws tsis kam rau postweld cracking, yog qhov zoo heev.
Qhov saum npoo hardening ntawm Inconel 718 yog dab tsi?
Alloy 718 yog hardened los ntawm nag lossis daus ntawm theem nrab (xws li gamma prime thiab gamma ob -prime) rau hauv cov hlau matrix. Cov nag lossis daus ntawm cov npib tsib xee - (aluminium, titanium, niobium) theem yog tshwm sim los ntawm kev kho cua sov hauv qhov kub ntawm 1100 txog 1500℃F.
Lub hardness ntawm 718 Inconel yog dab tsi?
Inconel 718 hardness sib txawv heev nrog kev kho cua sov, feem ntau xws li softer, machinable qib (ib ncig 20-35 HRC hauv cov tshuaj-annealed state) rau hnyav heev, hnub nyoog tej yam kev mob (txog 45-50 HRC) tom qab nag lossis daus hardening, muab lub zog zoo heev thiab hnav tsis kam rau cov ntawv thov.
