25Cr2MoVA sheet eshushu esongwayo

① Amadijithi amabini ekuqaleni kwenombolo yentsimbi abonisa umxholo wekhabhoni wentsimbi, ochazwe kumawaka alishumi omgangatho wekhabhoni ophakathi, njenge40Cr, 25Cr2MoVA ityhubhu yealloy.
②Ezona zinto ziphambili zokudityaniswa kwentsimbi, ngaphandle kwezinto ezixutyiweyo zodwa, zibonakaliswa ngokweepesenti ezimbalwa. Xa umxholo we-alloy ophakathi ungaphantsi kwe-1.5%, ngokubanzi kuphela isimboli se-element siboniswa kwinombolo yentsimbi, kwaye umxholo awuboniswanga. Nangona kunjalo, kwiimeko ezikhethekileyo, kulula ukubangela ukudideka, kwaye inombolo "1" inokumakishwa emva kwesimboli sento, njengenombolo yensimbi "12CrMoV" kunye ne "12Cr1MoV", yangaphambili inomxholo we-chromium we-0.4-0.6 %, le yokugqibela inomxholo we-chromium we-0.9-1.2%, kwaye zonke ezinye ziyafana. Xa umxholo oqhelekileyo wezinto ezixutywayo ngu ≥1.5%, ≥2.5%, ≥3.5%..., umxholo kufuneka uboniswe emva kwesimboli se-element, enokuthi ibonakaliswe njenge-2, 3, 4 ... njl njl. Umzekelo , 18Cr2Ni4WA.
③ Izinto ze-alloying ezifana ne-vanadium V, i-titanium Ti, i-aluminiyam AL, i-boron B, kunye ne-RE enqabileyo yomhlaba kwintsimbi zonke zi-microalloying elements. Nangona umxholo uphantsi kakhulu, kufuneka zisaphawulwe kwinombolo yentsimbi. Ngokomzekelo, kwintsimbi ye-20MnVB. I-Vanadium yi-0.07-0.12%, kunye ne-boron yi-0.001-0.005%.
④Intsimbi ekumgangatho ophezulu yomgangatho ophezulu kufuneka yongeze "A" ekupheleni kwenombolo yentsimbi ukuyahlula kwintsimbi ekumgangatho ophezulu.
⑤ Injongo ekhethekileyo ye-alloy yensimbi yesakhiwo, inombolo yentsimbi ifakwe ngaphambili (okanye ifakwe) kunye nesimboli emele injongo yentsimbi. Ngokomzekelo, i-30CrMnSi yentsimbi ekhethekileyo ye-screws ye-riveting, inombolo yentsimbi ichazwa njenge-ML30CrMnSi.
Imibhobho ye-alloy kunye nemibhobho engenamthungo zombini inxulumene kwaye ihluke, kwaye akufanele idideke.
Umbhobho we-alloy uchazwa ngumbhobho wensimbi ngokwezinto zokuvelisa (oko kukuthi, izinto), njengoko igama lithetha, ngumbhobho owenziwe nge-alloy; ngelixa umbhobho ongenamthungo uchazwa ngumbhobho wentsimbi ngokwenkqubo yokuvelisa (ingenamthungo kwaye ingenamthungo), umahluko ukusuka kumbhobho ongenamthungo yimibhobho yomthungo, kuquka imibhobho edityanisiweyo ethe tye kunye nemibhobho ejikelezayo.
