1. 45 # birta
Xaaladaha caadiga ah, haddii culeyska usha piston uusan aad u weyneyn, 45 # birta ayaa guud ahaan loo isticmaalaa wax soo saarka.Maadaama 45 # birta ay tahay kaarboon dhexdhexaad ah oo la demiyo iyo birta qaabdhismeedkeeda caadi ahaan loo isticmaalo, waxay leedahay awood sare iyo mashiin wanaagsan, gaar ahaan marka rullaluistuyada alxanka ahi dhaafo daaweynta kulaylka gaaska, waxay heli kartaa iska caabin gaar ah., balaastigga iyo xidhashada iska caabbinta, sidaa darteed waa mid ka mid ah waxyaabaha inta badan loo isticmaalo farsamaynta usha piston.
2. 40Cr bir
Haddii usha piston ay saaran tahay culays culus, guud ahaan waxa ay ka samaysan tahay bir dhan 40Cr.Maadaama birta 40Cr ay tahay kaarboon dhexdhexaad ah oo la demiyo oo bir dabcay, waxay leedahay adkeysi wanaagsan iyo iska caabin heerkul hooseeya.Gaar ahaan marka la demiyo oo la xanaaqo, waxay yeelan kartaa sifooyin farsamo guud oo heersare ah, iyo engegnaanta waxay gaari kartaa inta u dhaxaysa 32-36HRC, taas oo ah, inta u dhaxaysa qiyaastii 301-340HB, si ay usha piston u yeelato awood shaqo oo qancisa.Sidaa darteed, ulaha piston ee ka samaysan birta 40Cr ayaa inta badan loo adeegsadaa ulaha piston oo leh awood saameyn weyn leh iyo shuruudaha gudbinta culeyska culus.
Mawduuca kor lagu sharaxay waa agabka inta badan loo isticmaalo farsamaynta usha piston.Si kastaba ha noqotee, marka lagu daro labadan shay, GCr15 birta, Sus304… iwm. ayaa sidoo kale loo isticmaalaa in lagu sameeyo qalabka wax lagu sameeyo ee usha piston.Sidaa darteed, alaabta loo isticmaalo ka-habaynta ulaha piston waxaa inta badan lagu xushay baahidooda.Maaddooyinka kala duwan awgeed, dhinacyada qaarkood ama bandhigyada qaarkood, waxay sidoo kale yeelan doonaan faa'iidooyin ka duwan qalabka kale..
