SNCM22: Cov ntsiab lus nthuav dav

SNCM22 yog ib hom hlau hlau uas muaj ntau yam tseem ceeb thiab pom kev siv dav hauv ntau yam kev tsim vaj tsev thiab kev tsim khoom.

Hais txog cov tshuaj muaj pes tsawg leeg, SNCM22 feem ntau muaj cov ntsiab lus xws li npib tsib xee (Ni), chromium (Cr), molybdenum (Mo), thiab manganese (Mn), ntxiv rau hlau (Fe) ua lub hauv paus hlau. Cov proportions tshwj xeeb ntawm cov alloying ntsiab yog ua tib zoo tswj kom ua tiav cov khoom xav tau. Nickel imparts toughness, ductility, thiab tiv thaiv corrosion thiab kev ntxhov siab tawg. Chromium txhim kho hardness, hnav tsis kam, thiab oxidation kuj. Molybdenum ntxiv txhim kho lub zog thiab tawv tawv ntawm qhov kub thiab txias thiab tseem ua rau kom zoo dua hardenability. Manganese pab txhim kho cov hlau tag nrho cov cuab yeej cuab tam thiab hardenability thiab.

Hais txog cov khoom siv kho tshuab, SNCM22 nthuav tawm lub zog tensile siab, uas tso cai rau nws los tiv thaiv lub zog tseem ceeb yam tsis muaj kev tawg yooj yim. Nws muaj ductility zoo, ua kom nws deformed thiab zoo li tus thaum lub sij hawm tsim cov txheej txheem xws li forging, machining, thiab dov. Lub alloy kuj qhia tau zoo heev toughness, txhais tau tias nws muaj peev xwm nqus tau lub zog thiab tiv thaiv tam sim ntawd cuam tshuam, ua rau nws txhim khu kev qha nyob rau hauv cov ntaub ntawv uas dynamic loads koom. Nws hardness kuj yog siab, muab zoo hnav tsis kam, uas yog ib qho tseem ceeb rau cov khoom uas nyob rau hauv tas li kev sib cuag los yog muaj kev sib txhuam.
Hauv kev tsim khoom lag luam, SNCM22 feem ntau yog siv los tsim cov iav, shafts, thiab lwm yam khoom siv tseem ceeb. Nws yog qhov tsim nyog rau cov ntawv thov hauv kev lag luam tsheb, xws li hauv kev sib kis thiab cov khoom siv cav, qhov chaw muaj zog, ua haujlwm ntev, thiab tsis kam hnav thiab qaug zog yog qhov tseem ceeb. Nws kuj tseem siv rau hauv kev tsim cov tshuab hnyav thiab khoom siv vim nws muaj peev xwm ua tau zoo nyob rau hauv kev xav tau kev ua haujlwm.
Cov txheej txheem kho cua sov tuaj yeem siv rau SNCM22 txhawm rau txhim kho nws cov khoom ntxiv. Piv txwv li, quenching thiab tempering yuav siv tau los kho qhov hardness thiab toughness tshuav nyiaj li cas raws li cov kev cai tshwj xeeb ntawm daim ntawv thov. Zuag qhia tag nrho, SNCM22 yog ib qho tseem ceeb ntawm cov hlau alloy uas sib xyaw ua ke ntawm ntau yam khoom tsim nyog, ua rau nws yog ib qho khoom siv tseem ceeb hauv ntau qhov kev lag luam, pab txhawb kev ua haujlwm thiab kev ntseeg siab ntawm ntau yam khoom thiab tshuab.
