Qhov kev ua tau zoo ntawm 1.4948 yog dab tsi?
1.4948 stainless hlau muaj cov khoom zoo heev thiab tshwj xeeb tshaj yog siv rau hauv qhov kub thiab txias thiab corrosive ib puag ncig. Cov hauv qab no yog cov ncauj lus kom ntxaws txog nws cov yam ntxwv ua haujlwm:
Hais txog lub cev muaj zog: qhov ceev ntawm 1.4948 yog 7.93 g / cm³, lub zog tensile nyob nruab nrab ntawm 500 thiab 700 MPa, lub zog tawm los yog ntau dua los yog sib npaug rau 185 MPa, thiab qhov elongation yog tsawg kawg yog 40% nyob rau hauv qhov kev taw qhia longitudinal thiab 30% nyob rau hauv lub transverse kev taw qhia. Cov ntaub ntawv no qhia tau hais tias nws muaj cov khoom siv zoo.Heat resistance: Cov khoom no yog tshwj xeeb tshaj yog haum rau kub txog li 550 degree. Lub creep kuj ntawm 1.4948 ntawm qhov kub thiab txias yog txhim kho los ntawm qhov sib ntxiv ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb (REM). Corrosion kuj thiab vuam kev ua tau zoo: 1.4948 muaj corrosion kuj zoo thiab tuaj yeem tiv taus atmospheric corrosion thiab nruab nrab oxidation thiab txo qhov chaw. Nyob rau tib lub sijhawm, nws kuj muaj kev ua haujlwm zoo heev, uas ua rau nws yooj yim dua thiab yooj yim dua thaum lub sijhawm tsim khoom.
Cov khoom siv kho tshuab: Txawm tias qhov kub thiab txias, 1.4948 tuaj yeem tswj cov khoom zoo heev, xws li muaj zog oxidation tsis kam, kub tsis kam thiab ua haujlwm yooj yim. Qhov no ua rau nws siv dav hauv kev lag luam xws li aviation.
