27SiMn Alloy Seamless Steel Pipe

Kufotokozera Kwachidule:

Mapaipi achitsulo a 27SiMn amagwiritsidwa ntchito kwambiri m'mafakitale amagalimoto, petroleum, mankhwala ndi zotumiza.27SiMn chitsulo chitoliro chimakhala chokhazikika komanso chokhazikika, ndikukutidwa ndi phosphate mkati ndi kunja.Chitoliro chachitsulo ichi chimagwiritsidwa ntchito makamaka pakuzimitsidwa ndi kupsya mtima popanga zida zopondera zotentha (zigawo zama hydraulic) zomwe zimafuna kulimba kwambiri komanso kukana kuvala, komanso kupondaponda kotentha komwe kumafunikira kulimba kwambiri komanso kukana kuvala.

27SiMn opanda zitsulo chitoliro ali kuuma mkulu, yovuta hardability awiri m'madzi ndi 8 ~ 22mm, machinability wabwino, sing'anga ozizira mapindikidwe plasticity ndi weldability;Kuonjezera apo, kulimba kwa chitoliro chachitsulo sikumachepetsedwa kwambiri panthawi ya chithandizo cha kutentha, koma kumakhala ndi mphamvu zambiri komanso kukana kuvala, makamaka pozimitsa madzi.
