SCr3 Hlau
Nov 15, 2022
SCr3 steel yog ib hom hlau alloy nrog cov yam ntxwv sib txawv thiab ntau yam kev siv.
Cov hlau no paub txog nws cov khoom siv kho tshuab zoo heev. Nws muaj lub zog tensile siab thiab zoo ductility, tso cai rau nws tiv taus kev ntxhov siab thiab deformation yam tsis muaj fracturing. Kev sib xyaw ua ke ntawm lub zog thiab ductility ua rau SCr3 steel haum rau cov ntawv thov uas cov khoom raug cuam tshuam rau cov khoom hnyav thiab cuam tshuam.
Cov tshuaj muaj pes tsawg leeg ntawm SCr3 steel muaj xws li chromium ua ib qho tseem ceeb alloying caij. Chromium txhim kho cov hlau hardness, hnav tsis kam, thiab corrosion kuj. Nws tsim cov txheej txheem oxide tiv thaiv ntawm cov hlau, tiv thaiv xeb thiab oxidation. Qhov no ua rau SCr3 steel haum rau siv nyob rau hauv ib puag ncig uas raug rau ya raws thiab corrosive tshuaj yog ib qho kev txhawj xeeb.
Ntxiv nrog rau chromium, SCr3 steel kuj tseem muaj me me ntawm lwm cov ntsiab lus xws li manganese, silicon, thiab molybdenum. Cov ntsiab lus no ua rau cov hlau tag nrho cov khoom thiab tuaj yeem hloov kho kom tau raws li cov kev thov tshwj xeeb.
SCr3 steel yog dav siv nyob rau hauv kev lag luam tsheb rau kev tsim cov iav, ncej, thiab lwm yam kis tau tus mob. Nws lub zog siab thiab hnav tsis kam ua rau nws zoo tagnrho rau kev tiv thaiv qhov hnyav thiab kev sib txhuam tsim hauv cov ntawv thov no. Nws kuj tseem siv rau hauv cov tshuab thiab cov cuab yeej tsim khoom lag luam rau cov khoom uas xav tau kev ua haujlwm ntev thiab kev ntseeg siab.
Kev tsim cov txheej txheem ntawm SCr3 steel yuav tsum ceev faj tswj cov ntsiab lus alloying, melting, thiab kev kho cua sov. Cov txheej txheem ntau lawm yog ua haujlwm los xyuas kom meej qhov zoo thiab ua haujlwm zoo. Cov txheej txheem kho cua sov xws li quenching thiab tempering tuaj yeem siv los txhim kho cov khoom siv ntawm cov hlau.
Nyob rau hauv xaus, SCr3 steel yog ib qho tseem ceeb alloy steel nrog zoo heev mechanical zog, hnav tsis kam, thiab corrosion kuj. Nws cov yam ntxwv tshwj xeeb ua rau nws haum rau ntau yam kev siv hauv ntau yam lag luam. Txawm hais tias nws yog rau cov khoom siv tsheb lossis cov khoom siv, SCr3 steel muab kev ua tau zoo thiab ua haujlwm ntev.
