Khoom Description
cev 25cr4
Qhov zoo ntawm Tube 25crmo4
- Tube 25CrMo4 tuaj yeem ua kom sov-kho, los ntawm kev quenching thiab tempering, kom ua tiav kev sib xyaw ua ke ntawm hardness, lub zog, thiab ductility rau cov khoom uas yuav tsum tau muaj cov khoom siv tshwj xeeb.
- Tube 25CrMo4 lub zog siab thiab qaug zog ua rau nws zoo tagnrho rau yob tawb, caj npab ncua kev kawm ntawv, tsav shafts, thiab chassis Cheebtsam uas muaj kev vibration thiab dynamic loads.
- Tube 25CrMo4 qhia tau zoo heev - qhov kub thiab txias, ua kom muaj kev ruaj ntseg ua haujlwm nyob rau hauv ib puag ncig raug kub siab, xws li cav nacelles hauv kev siv aerospace.
Daim ntawv thov ntawm Tube 25crmo4
- Kev lag luam tsheb: Roll tawb thiab chassis thav duab, ncua kev caj npab thiab cov khoom siv, tsav ncej, thiab cov kauj tsheb rau kev sib tw thiab siab - tsheb ua haujlwm.
- Kev lag luam Aerospace: Airframe structural tubes thiab lub teeb yuag kev txhawb nqa qauv, hydraulic kab, tsaws iav Cheebtsam, thiab actuation systems.
- Mechanical Engineering: Tig cov khoom siv kho tshuab hauv gearboxes thiab kis tau tus mob, precision mechanical qhov chaw xws li shafts, bushings, thiab cylindrical vaj tse.
- Siab -Siab thiab Hydraulic Systems: Hydraulic thiab pneumatic thooj voos kheej kheej, siab - cov kav xa dej siab, thiab lwm yam.
