20CrMo xaashi bir duuban oo kulul

birta wareegsan ee birta ah ayaa si weyn loogu isticmaalaa samaynta mishiinada, samaynta baabuurta, tareenka, mishiinada macdanta, mishiinka petoleum, mishiinada beeraha iyo dhismaha madaniga ah sida dhammaan noocyada kala duwan ee shafts, boolal, ulo isku xidha, qalabka hardware, marsho, qaybaha caadiga ah, spanners, qaab dhismeedka qaybaha baabuurta iyo mishiinada beeraha, gacmaha dibadda iyo gudaha, rollers iyo kubadaha samaynta.
GB 20CrMo steel waa nooc ka mid ah birta daawaha Shiineeska ah ee injineernimada iyo ujeeddada qaab dhismeedka makaanikada, kaas oo guud ahaan loo isticmaalo deminta ama dabcinta ama bakhtiinta iyo deminta. Walaxda 20CrMo waxay leedahay kuleyl aad u sarreeya, adkeysi wanaagsan, majiro xanaaq, caag qabow, mashiin wanaagsan iyo alxan.

Codsiyada

20CrMo aluminium bir ah waxaa loo isticmaalaa soo saarista warbaahinta aan daxalka ahayn ee qalabka kiimikada iyo tuubooyinka cadaadiska sare, xirmooyinka, marawaxadaha uumiga, boogaha kuleyliyaha iyo foornada leh heerkulka shaqada ee ka hooseeya 250 ° C, iyo qaybaha muhiimka ah ee carburizing sida gears iyo shafts ee mashiinnada guud . Waxa kale oo loo isticmaali karaa meel ka mid ah birta 1Cr13 si loo soo saaro cadaadis dhexdhexaad ah, marawaxadaha uumiga cadaadiska hooseeya ee kuleyliyaha sare ee heerka cadaadiska heerkulbeegyada shaqada.

Tilmaamaha Daaweynta Kulaylka
