1. 45 # steel
Raws li ib txwm muaj, yog tias lub piston pas nrig tsis loj heev, 45 # steel feem ntau yog siv rau kev tsim khoom.Txij li thaum 45 # steel yog ib qho uas feem ntau siv nruab nrab carbon quenched thiab tempered structural steel, nws muaj zog thiab zoo machinability, tshwj xeeb tshaj yog thaum cov welded roller thav duab tau dhau los ntawm kev kho cua sov, nws tuaj yeem tau txais qee yam kev tiv thaiv., plasticity thiab hnav tsis kam, yog li nws yog ib qho ntawm cov khoom siv ntau dua rau kev ua piston pas nrig.
2.40Cr steel
Yog hais tias lub piston pas nrig yog nyob rau hauv hnyav load, nws yog feem ntau yog ua los ntawm 40Cr steel.Txij li thaum 40Cr steel yog nruab nrab carbon quenched thiab tempered steel, nws muaj hardenability zoo thiab kub tsis tshua muaj kev cuam tshuam.Tshwj xeeb tshaj yog thaum nws yog quenched thiab tempered, nws muaj peev xwm ua tau zoo heev txhua yam khoom, thiab lub hardness yuav ncav cuag ntawm 32-36HRC, uas yog, ntawm txog 301-340HB, thiaj li hais tias tus pas nrig piston muaj peev xwm txaus siab ua hauj lwm lub zog.Yog li ntawd, piston pas nrig ua los ntawm 40Cr steel feem ntau siv nyob rau hauv piston rods nrog loj cuam tshuam quab yuam thiab hnyav load kis tau tus mob yuav tsum tau.
Cov ntsiab lus piav qhia saum toj no yog cov khoom siv ntau dua rau kev ua cov pas nrig piston.Txawm li cas los xij, ntxiv rau ob cov ntaub ntawv no, GCr15 steel, Sus304 ... thiab lwm yam kuj tseem siv los ua cov khoom siv piston pas nrig.Yog li ntawd, cov ntaub ntawv siv rau kev ua cov piston pas nrig yog xaiv raws li lawv tus kheej xav tau.Vim muaj cov ntaub ntawv sib txawv, hauv qee yam lossis qee qhov kev ua yeeb yam, lawv kuj yuav muaj qee qhov zoo uas txawv ntawm lwm cov ntaub ntawv..
