FAQ
42CrMo4 steel yog dab tsi?
42CrMo4 yogib tug engineering alloy hlau uas muaj chromium thiab molybdenum. Nws muaj zog qaug zog, puas thiab cuam tshuam tsis kam, toughness, thiab torsional zog. Nws tuaj yeem raug kho cua sov hauv ntau txoj hauv kev los muab nws ua ke zoo tshaj plaws ntawm cov khoom.
Puas yog 42CrMo4 zoo ib yam li 4140?
42CrMo4 thiab 4140 yog qhov tseem ceeb tib qib steel. Ob leeg xa mus rau qis- alloy, siab- lub zog hlau uas yog tsev neeg ntawm chromium-molybdenum steels. 42CrMo4 yog European tsim raws li EN 10083 tus qauv, thaum 4140 yog Asmeskas kev xaiv raws li AISI / SAE system.
Qhov txawv ntawm C45 thiab 42CrMo4 yog dab tsi?
42CrMo steel muaj lub zog tensile ntau dua li C45 steel vim muaj chromium thiab molybdenum. Qhov no txhais tau tias nws tuaj yeem tiv taus cov khoom hnyav thiab kev ntxhov siab ntau dua yam tsis muaj kev tawg lossis deforming. Yog li ntawd nws yog qhov zoo tagnrho rau kev siv lub luag haujlwm hnyav uas xav tau lub zog siab thiab kav ntev.
