Ukuthengiswa kwewaranti ye-30CrMo yomenzi wepayipi yensimbi ye-alloy
I-30CrMo ingxubevange yombhobho yentsimbi inomxholo wekhabhoni we-0.26 ~ 0.34, umxholo wesilicon ye-0.17 ~ 0.37, umxholo we-manganese we-0.40 ~ 0.70, umxholo we-molybdenum we-0.15 ~ 0.25, umxholo we-chromium we-0.80 ~ 1.10. Kukho zombini ubudlelwane kunye nokwahlukana phakathi kombhobho we-alloy kunye nombhobho ongenamthungo, ongenakudideka. Umbhobho we-alloy uchazwa njengombhobho wensimbi ngokwemathiriyeli yokuvelisa (okt imathiriyeli). Njengoko igama libonisa, ngumbhobho owenziwe nge-alloy; Umbhobho ongenamthungo uchazwa ngokwenkqubo yokuvelisa umbhobho wentsimbi (umthungo ongenamthungo). Yintoni eyahlukileyo kumbhobho ongenamthungo ngumbhobho ongenamthungo, kuquka umbhobho odityanisiweyo othe ngqo kunye nombhobho ojikelezayo. 35CrMo, 16-50mn, 27SiMn, 40Cr, Cr5Mo 12Cr1MoV 12Cr1MoVG 15CrMo 15CrMoG 15CrMoV 13CrMo44 T91 27SiMn 25CrMo 12CrMoVG 12Cr1MoVG 15CrMo 15CrMoG 15CrMoV 13CrMo44 T91 27SiMn 25CrMo 40CrMo 40CrMo 30CrMo 30CrMo 30CrMo 30Cr 30Cr 301 P22.p91.

Ibakala lentsimbi, elifinyeziweyo njengebakala lentsimbi, ligama lemveliso ethile yentsimbi. Lulwimi oluqhelekileyo ukuba abantu baqonde intsimbi. E-China, uphawu oluqinileyo lubonakaliswa ngokubanzi ngokudityaniswa koonobumba baseTshayina bePinyin, iisimboli zekhemikhali kunye neenombolo zesiArabhu.
Emva koko, siya kwazisa intsingiselo yezinto kunye neempawu kwintsimbi ye-alloy
Iidijithi ezimbini ekuqaleni kwebakala lensimbi zimela umxholo wekhabhoni yensimbi, echazwe njengamawaka ambalwa omxholo wekhabhoni, njenge-40Cr.
Izinto eziphambili ze-alloying kwintsimbi, ngaphandle kwezinto ezixutywe nge-microalloyed, zibonakaliswa ngokubanzi ngeepesenti ezimbalwa. Xa umxholo we-alloy ophakathi ungaphantsi kwe-1.5%, kwibakala lensimbi
Ngokubanzi, kuphela isimboli sento ephawulweyo, kodwa umxholo awuphawulwanga. Nangona kunjalo, ukuba kulula ukubhidaniswa phantsi kweemeko ezikhethekileyo, inombolo "1" inokumakishwa emva kwesimboli sento,
Ngokomzekelo, kumabanga entsimbi "12CrMoV" kunye ne "12Cr1MoV", umxholo wechromium yangaphambili ngu-0.4-0.6%, kwaye leyo yokugqibela yi-0.9-1.2%, kunye namanye amacandelo afanayo.
Xa umxholo oqhelekileyo wezinto ze-alloy ≥ 1.5%, ≥ 2.5%, ≥ 3.5%... Umxholo uya kuboniswa emva kwesimboli se-elementi, esinokubonakaliswa njenge-2 kunye ne-3 ngokufanelekileyo.

Umzekelo, 18Cr2Ni4WA.
I-Vanadium V, i-titanium Ti, i-aluminium i-Al, i-boron B, i-RE enqabileyo yomhlaba kunye nezinye izinto ze-alloy kwintsimbi ziyinxalenye ye-microalloyed elements. Nangona umxholo uphantsi kakhulu, kufuneka usekho kwibakala lentsimbi
Phawula. Ngokomzekelo, kwi-20mnvb yensimbi, i-vanadium yi-0.07-0.12% kunye ne-boron yi-0.001-0.005%.
Intsimbi ekumgangatho ophezulu iya kuphawulwa "a" ekupheleni kwebakala lentsimbi ukuhlula kwintsimbi yezinga eliphezulu.
Kwi-alloy structural steel for special purpose, ibakala lensimbi lilandelwa (okanye isimamva) ukumela isimboli senjongo yentsimbi. Umzekelo, intsimbi ye-30CrMnSi ye-riveting screw,
Ibakala lentsimbi liboniswa njenge ml30crmnsi.
Kwintsimbi ephantsi ye-alloy ephantsi, iya kuboniswa ekupheleni komgangatho wentsimbi. Ngokomzekelo, intsimbi ye-16Mn, intsimbi ekhethekileyo esetyenziselwa iibhulorho "16Mnq", i-steam
Inqanaba elikhethekileyo lensimbi yentsimbi "16MnL", kunye nenqanaba elikhethekileyo lentsimbi yesitya soxinzelelo "16MnR".
