Imibuzo Evame Ukubuzwa
Iyini insimbi yesikhunta ye-DIN 1.2738?
I-DIN 1.2738 iyinsimbi yepulasitiki eqinisiwe ehlanganiswe ne-nickel evame ukubizwa ngokuthi i-P20+Ni. Yenzelwe ukusebenza kahle, ukuqina kanye nokuqina okufanayo ezingxenyeni ezinkulu zesikhunta.
Yibuphi ubulukhuni obuvame ukunikezwa yi-1.2738?
Ububanzi bokuphakelwa obuvamile bungaba ngu-290–330 HB. Ububanzi bokuqina kwangempela, izikhundla zokulinganisa kanye nokwehluka okuvunyelwe kufanele kuchazwe ngokwencazelo ye-oda futhi kuqinisekiswe yi-MTC.
Uyini umehluko phakathi kuka-1.2738 no-P20?
I-1.2738 ivame ukuchazwa ngokuthi i-P20+Ni ngoba iqukethe i-nickel eyengeziwe uma iqhathaniswa nensimbi eyisisekelo yohlobo lwe-P20. I-nickel ithuthukisa ukuqina futhi iyenza ifaneleke kakhulu kumabhulokhi amakhulu esikhunta adinga ukufana okungcono kokuqina.
Ingabe i-1.2738 ingapholishwa ukuze kusetshenziswe izingxenye zepulasitiki ezibonakalayo?
Yebo, i-1.2738 ekhiqizwe kahle futhi yacutshungulwa inganikeza imiphumela emihle yokupholisha kanye nokusika izithombe. Umbuzo kufanele usho izinga lokupholisha noma ukuthungwa okudingekayo ukuze kukhethwe ikhwalithi yensimbi efanelekile kanye nokulungiswa kwendawo.
Ingabe ipuleti elingu-1.2738 lingafakwa i-nitride?
I-nitriding ingasetshenziswa ukuthuthukisa ubulukhuni bendawo kanye nokumelana nokuguguleka. Izinga lokushisa le-nitriding kanye nenqubo kumele kukhethwe ukuze kugwenywe ukuthamba okungafuneki noma izinguquko zobukhulu bezinto eziyisisekelo eziqinisiwe.
Ingabe ukuhlolwa kwe-ultrasonic kuyatholakala kumabhulokhi esikhunta amakhulu?
Yebo. I-UT ingalungiselelwa amapuleti aminyene kanye namabhulokhi esikhunta ahlanganisiwe uma kuchazwe. I-oda lokuthenga kufanele lisho izinga lokuhlola, izinga lokwamukelwa, ukumbozwa kokuskena kanye nezidingo zombiko.
Ingabe i-SAKY STEEL inganikeza izikhala zesikhunta ezenziwe ngokwezifiso?
Izimbobo ezisikiwe ngesarha, ezigayiwe, ezigayiwe kanye nezifakwe umshini oqinile zingaxoxwa ngokuya ngomdwebo. Ubukhulu bokugcina, imvume yomshini, ukuthamba, ukulingana kanye nezidingo zomphezulu kufanele kufakwe ocwaningweni.
Ingabe i-MTC kanye ne-EN 10204 3.1 zinganikezwa?
I-MTC, ukulandeleka kwenombolo yokushisa kanye nemibhalo ye-EN 10204 3.1 inganikezwa ngokwe-oda lokuthenga. Ukuqina okwengeziwe, ubukhulu, ukugoba noma imibiko ye-UT nakho kungahlelwa.
