Intshayelelo yemveliso
Yintoni i-AISI 5140 yentsimbi?
Ibakala le-ASTM 5140 lelinye ibakala lentsimbi yolwakhiwo kwi-ASTM A29 esemgangathweni osetyenziswa ngokubanzi. I-5140 ipleyiti yensimbi isetyenziswa ngokubanzi kwiindawo eziphantsi kunye nezimodareyitha ezigxininiswe kwizithuthi, iinjini kunye noomatshini apho kunzima, ukunxiba ukuxhathisa indawo kuyadingeka. I-Gnee yingcali ye-5140 yepleyiti kunye nomthengisi webha engqukuva kwaye sigcina uluhlu olubanzi lwesayizi ye-5140 yepleyiti esitokhweni ukuze ithunyelwe ngokukhawuleza. Qhagamshelana nathi ngayo nayiphi na i-AISI 5140 isicelo sempahla yepleyiti kunye nexabiso eliphezulu le-5140 yexabiso lentsimbi.
Inzuzo yoKhuphiswano ye-AISI 5140 ipleyiti yentsimbi e-Otai:
- Ifumaneka kwisitokhwe ukuze ithunyelwe ngokukhawuleza
- Amandla aphezulu,
- Ukunyamezela okuphezulu
- Ukuqina okulungileyo
- Ukuchasana okuphezulu kwiipropati ze-thermal.
- Ixabiso lokukhuphisana
1. Uluhlu lonikezelo lwe-AISI/ASTM 5140
Ibha eRound: ububanzi 20mm - 300mm
Ipleyiti yentsimbi kunye neBlock yentsimbi: ubukhulu 10-200mm x ububanzi 300-2000mm
- I-10-80mm ubukhulu be-5140 ipleyiti iyafumaneka ngalo lonke ixesha kwisitokhwe,
- I-90-200mm ipleyiti yobukhulu iza kuba yimveliso entsha kwiintsuku eziyi-15-30 zokukhokela.
UkuGqiba komphezulu: uMphezulu oMnyama, uMphezulu oMiliweyo okanye uMphezulu oGcwecwe ngokweemfuno ezinikiweyo.
