Iibhola ze-430 zensimbi ezingenasici zinokumelana ne-corrosion engaphantsi kwe-302 okanye i-304 yeebhola zentsimbi.Baxhathisa emanzini ahlambulukileyo, i-steam, umoya, i-detergents, iisepha, i-organic and oxidated acids, izisombululo ze-alkaline.Abaxhathisi kwi-chloride, i-fluoride, i-bromide, isisombululo se-iodide.Ayiqini ukuba ubushushu bunyangwa.

● Siye sabandakanyeka kwimveliso yebhola yensimbi ngaphezu kweminyaka engama-26;
● Sinikezela ngeentlobo ezahlukeneyo zobukhulu ukusuka kwi-3.175mm ukuya kwi-38.1mm.Ubukhulu obungavumelekanga kunye neegeyiji zinokuveliswa phantsi kwesicelo esikhethekileyo (njenge-5.1mm, 5.15mm, 5.2mm, 5.3mm 5.4mm yendlela yokuhlala; 14.0mm ye-cam shaft kunye ne-CV joint, njl.);
● Sinobukho besitokhwe esibanzi.Uninzi lweesayizi ezisemgangathweni (3.175mm ~ 38.1mm) kunye neegeji (-8 ~ + 8) zikhoyo, ezinokuhanjiswa ngokukhawuleza;
● Ibhetshi nganye yeebhola ihlolwa ngoomatshini abantsonkothileyo: umvavanyi okungqukuva, umvavanyi uburhabaxa, imicroscope yohlalutyo lwe-metallographic, uvavanyo lokuqina (HRC kunye ne-HV) ukuqinisekisa umgangatho.
Umbuzo: Ndikhetha njani uphawu olufanelekileyo lwensimbi engenasici (304 (L) / 316 (L) / 420 (C) / 440 (C))?Zeziphi umahluko ophambili phakathi 300 kunye 400 series iibhola stainless steel?
A: Ukukhetha uphawu olufanelekileyo lwentsimbi yeebhola zensimbi ezingenasici, kufuneka sizazi kakuhle iimpawu zophawu ngalunye kunye nokusetyenziswa kweebhola.Iibhola zensimbi ezingenasici eziqhelekileyo ezisetyenziswayo zingahlulwa ngokulula kumaqela amabini: uchungechunge lwe-300 kunye ne-400 series.
300 series "austenitic" iibhola steel stainless ziqulathe ngakumbi chromium kunye nezinto nickel kwaye ngokwethiyori non-magnetic (eneneni ziphantsi kakhulu-magnetic. Ngokupheleleyo non-magnetic zifuna ukongezwa ubushushu unyango.).Ngokuqhelekileyo ziveliswa ngaphandle kwenkqubo yokunyanga ukushisa.Banokumelana ne-corrosion engcono kune-400 series (enyanisweni, uxhathiso oluphezulu lwe-corrosion yeqela elingenasici. Nangona iibhola ezingama-300 zonke zixhathisa, kodwa 316 kunye neebhola ze-304 zibonisa ukuchasana okwahlukileyo kwinto ethile. Ukuze ufumane iinkcukacha ezithe vetshe, nceda ubhekisele kumaphepha iibhola ezahlukeneyo zentsimbi) .Azinabunewunewu kancinci, ngoko ke zinokusetyenziselwa ukutywinwa.Iibhola ze-400 zensimbi ezingenasici ziqulethe i-carbon eninzi, eyenza ibe yimagnethi kunye nobunzima obuninzi.Zinokuphathwa lula ngobushushu njengeebhola zentsimbi ye-chrome okanye iibhola ze-carbon steel ukunyusa ubulukhuni.Iibhola ze-400 zensimbi ezingenasici ziqhelekileyo zisetyenziselwa izicelo ezifuna ukuxhathisa kwamanzi, amandla, ukuqina kunye nokuxhatshazwa kokugqoka.
