Zopangiraali ndi tanthauzo lofika patali pa moyo wathu watsiku ndi tsiku, ndipo palinso magulu ndi mitundu yambiri. Ena a iwo aliamatchedwa kufa forgings. Thekufa kusakaayenera kugwiritsidwa ntchito mukukonza ndondomeko, ndiye kodi zopeka zidzakhudza moyo wakufa? Zotsatirazi ndizomwe mukuyambitsa mwatsatanetsatane:

Malinga ndi alloying digiri ya kufa zitsulo, ochiritsirazitsulo zotenthaku China ndi 5CrNiMo ndi 5CrMnM.Such wamba kalasi ya nkhungu zitsulo ndi 4Cr5W2VSi, 4Cr5MoVlSi, 4Cr5MoVSi, 3Cr2W8V ndi wodzipanga 3Cr3Mo3VNb, 3Cr2MoVNi (B2), 3VN (B2), 3VN (B2) 35Cr3Mo3W2V (HM1), 25Cr3Mo3VNb (HM3), 4Cr3Mo3W4VTiNb (GR), 5Cr4W5Mo2V (RM2), 50Cr4Mo3SiMnVAl (012A1), 6Cr4Mo3Si2WV(CG20), etc.

Die zitsulo ndi digiri apamwamba aloyi; Zitsulo wamba ozizira kufa monga CrWMn, Crl2, Crl2MoV, etc., 7CrSiMnMoV (CH), 65Cr4W3Mo2VNb (65Nb), SLM-LL, 6W8Cr4VTi (LMl), ndi carbide simenti-simenti yopangidwa ndi China.

Mtengo wakale ndi wotchipa, koma kugwiritsa ntchito momveka bwino kumakhala kocheperako, moyo ndi waufupi; ndipo magwiridwe antchito amtsogolo amakhala abwinoko, moyo ndi wautali, koma mtengo wake ndi wokwera mtengo.kupangira magawo, kufa kusakaumisiri ndi forging zipangizo conditions.Generally kulankhula, kusankha mtengo wokwera pang'ono koma zotsika mtengo zapamwamba nkhungu zipangizo chuma kwambiri.
