Soo saaraha 42CrMo4 ASTM 4140 42CrMo Hot Rolled Alloy Alloy Steel tube tube
Sharaxaad Gaaban:
42CrMo aluminium bir ah oo aan kala go 'lahayn waa bir aad u sareysa oo leh xoog sare iyo adayg, adkeysi wanaagsan, aan lahayn dabacsanaan cad, iyo qallafsanaan yar inta lagu jiro deminta.Deminta iyo xanaaqa ka dib, 42CrMo aluminium biibiile ah ayaa leh xad daal sare leh iyo iska caabin saameyn badan, saameyn wanaagsan oo adkeysi heerkul hoose ah, iyo xoog sare oo gurguurta iyo xoog adkeysi heerkul sare.Deminta dusha sare ee deminta iyo xanaaqa ka dib waxaa badanaa loo isticmaalaa nidaamka daawaynta kulaylka ee 42CrMo aluminium tubooyinka aan xidhnayn.
Waxaan hadda haysanaa shaqaale tayo sare leh oo wax ka qabta weydiimaha macaamiisha.Hadafkayagu waa "100% buuxinta macaamilka ee alaabtayada ama adeegayagu waa mid aad u fiican, iibinta qiimaha iyo adeegayaga shaqaalaha" oo aan ku raaxayno caannimada weyn ee macaamiisha dhexdooda.Iyada oo leh warshado badan, waxaan ku siin karnaa noocyo kala duwan oo soo saaraha ah 42CrMo4 ASTM 4140 42CrMo Hot Rolled Alloy Steel Tube Pipe, Hadafka ugu weyn ee shirkadeena waxay noqon doontaa inaan ku noolaado xasuus qancisa dhammaan rajada, iyo abuurista muddo dheer ganacsiga ganacsiga xiriirka jaceyl ee iibsada iyo isticmaalayaasha meel kasta oo meeraha ah.
