Waa maxay AISI 5140 birta?
ASTM fasalka 5140 waa hal darajo daawaynta daawaha dhismaha ee ASTM A29 heerka codsiga guud. 5140 saxan bir ah ayaa si weyn loogu isticmaalaa qaybo hooseeya oo dhexdhexaad ah oo loogu talagalay baabuurta, matoorada iyo mashiinnada meelaha adag, xirashada dusha iska caabinta looga baahan yahay. Gnee waa alaab-qeybiye 5140 saxan ah iyo alaab-qeybiyeyaal wareeg ah waxaanan ku haynaa cabbir ballaaran oo 5140 saxan ah oo kayd ah si degdeg ah loo raro. Nala soo xidhiidh wixii codsi ah AISI 5140 saxan ah iyo qiimaha ugu fiican ee 5140.
Faa'iidada tartanka ee AISI 5140 saxan bir ah oo ku taal Gnee:
Wareegga Wareegga: dhexroorka 20mm - 300mm
Saxanka birta iyo xannibaadda birta: dhumucdiisuna tahay 10-200mm x ballac 300-2000mm
Dhammaystirka Dusha sare: Dusha Madow, Dusha-Dhagax-Dhagaxsan ama Dusha La Sifeeyay sida shuruudaha la bixiyay.
