Izingxenye eziningi ezigxile ekukhungathekeni zichazwe cishe ku-400 HBW kuya ku-600 HBW, kodwa ububanzi obufanele buxhomeke ekusetshenzisweni nasekuhlolweni kwendlela.
4. Yiziphi izindinganiso okufanele ngizicele lapho ngithenga izingxenye ze-alloy ezenziwe ngokwezifiso?
Cela indinganiso yokuhlola, isitifiketi sezinto ezibonakalayo, kanye nendlela yokuhlola. I-ASTM E10 futhi I-ISO 6506-1 ziyizinkomba eziwusizo zokuhlola ubulukhuni.
5. Yini ebangela ukuthi izingxenye ezigugile zingasebenzi kahle kusenesikhathi ngisho noma ingxubevange ilungile?
Ukulingana okungahambi kahle, ukushisela okungahambi kahle, ukuphakamisa ukucindezeleka okubukhali, ukujiya okungalungile, kanye nokufakwa okungalungile konke kunganciphisa isikhathi senkonzo.
6. Ngingazi kanjani ukuthi ngidinga isisombululo se-alloy esenziwe ngokwezifiso?
Uma imishini yakho ibona ukuguguleka okungavamile, ukushayisana okuphindaphindiwe, ukugqwala, noma isikhathi sokungasebenzi njalo engxenyeni efanayo, incazelo ye-alloy eyenziwe ngokwezifiso ivame ukuba nesizathu.
7. Yini okufanele umhlinzeki omuhle ayinikeze ngaphambi kokuqala kokukhiqiza?
Ukubuyekezwa komdwebo, isincomo sezinto ezibonakalayo, indinganiso yokuhlolwa, isikhathi sokuhola, kanye nohlu olucacile lwezindlela zokwamukelwa.
