Khoom Description
Peb Qhov Zoo
1. Zoo heev hnav thiab corrosion kuj
- Cov chromium thiab molybdenum nyob rau hauv peb 38CrMoAl alloy tubes txhim khu lub hardness thiab txo cov khoom poob vim kev sib txhuam, ua rau lawv tsim nyog rau cov khoom raug rov qab kev nyuaj siab los yog mechanical hnav.
- Cov raj tau txais kev sim tshuaj lom neeg muaj pes tsawg leeg los xyuas kom meej tias cov ntsiab lus chromium thiab molybdenum ua tau raws li cov qauv kev qhia tshwj xeeb lossis cov neeg siv khoom xav tau, lav lub sijhawm ntev - lub sijhawm ua haujlwm nyob rau hauv siab - qhov kub thiab txias ib puag ncig.
2. Superior Surface Quality
- Peb 38CrMoAl alloy tubes yog tsim los siv cov txheej txheem kos duab txias, ua rau muaj qhov siab ntawm qhov smoothness, cov phab ntsa tuab, thiab tsis muaj nplai.
- Cov raj tau txais kev tshuaj xyuas qhov muag, kuaj qhov roughness ntawm qhov chaw, thiab tsis yog -kev kuaj xyuas kom ntseeg tau tias qhov chaw tsis muaj khawb, dents, lossis nplai.
3. Siab Dimensional raug
- Peb cov raj yog tsim los siv cov txheej txheem kub hnyiab thiab txias txheej txheem, kom ntseeg tau tias cov txheej txheem sab nraud, phab ntsa tuab, thiab kev ua siab ntev ua tau raws li cov neeg siv khoom xav tau.
- Cov hlab ntsha raug tswj xyuas los yog quenching thiab tempering kev kho mob kom tshem tawm cov kev ntxhov siab uas tshwm sim thaum lub sij hawm tsim, tiv thaiv deformation, ovality, los yog khoov thaum ua thiab tom qab kev kho mob.
4. Zoo heev mechanical zog
- Peb cov hlau alloy muaj lub zog tensile siab, lub zog tawm los, thiab lub zog, muaj peev xwm txhawb nqa hnyav - lub luag haujlwm tsav shafts, crankshafts, gears, thiab piston rods yam tsis muaj deformation lossis puas.
- Cov raj tau raug kuaj xyuas cov cuab yeej cuab tam nruj thiab tsis yog -kev sim ua kom puas tsuaj kom ntseeg tau tias lub raj zoo ua tau raws li ASTM, DIN, EN, thiab lwm yam kev qhia tshwj xeeb.
thaj chaw thov
