Umsesane wokufa udla ngokwenziwa ngentsimbi ye-carbon structural, i-structural alloy steel, kunye nentsimbi engenasici ngokubumba, ukusika, ukugrumba, unyango lobushushu kunye nezinye iinkqubo. Izinto ezisetyenziswa kwindandatho ziyafa kwaye inkqubo nganye yokucubungula inefuthe elithe ngqo kubomi bayo benkonzo, umgangatho wegranulation kunye nesiphumo. I-Carbon structural steel iqulathe ubukhulu becala intsimbi engama-45, ubulukhuni bayo bonyango lobushushu ngokuqhelekileyo i-HRC45 ~ 50, kwaye ukuxhathisa kwayo ukunxitywa kunye nokumelana nomhlwa akubi, eziye zapheliswa; Intsimbi ye-alloy ikakhulu iqulathe izinto ezingama-20CrMnTi, eziphantsi konyango lobushushu obungaphezulu njenge-carburization yomhlaba. Ukuqina konyango kungaphezulu kwe-HRC50 kwaye ineempawu ezilungileyo ezibanzi zoomatshini. Isikhunta sendandatho esenziwe ngolu hlobo sinamandla aphezulu kunye nokumelana nokunxiba okungcono kunentsimbi engama-45, kodwa ukungonakali kwayo kukunganyangeki kwe-corrosion. Nangona ixabiso le-mold ring enye liphantsi, ixabiso lokuvelisa iitoni zezinto eziphathekayo liphezulu kunelo lokubumba kwentsimbi yensimbi engenasici xa lisetyenziswa, kwaye ngoku liphelile; Izinto zensimbi ezingenasici ikakhulu ziyi-4Cr13. Ukuqina kunye nokuqina kwezi zixhobo zilungile. Unyango lobushushu kukudubula ngokubanzi, ubunzima bukhulu kune-HRC50 kwaye inokumelana nokunxiba okufanelekileyo kunye nokuxhathisa umhlwa. Ubomi benkonzo bude, kwaye ixabiso lokungunda kwetoni nganye liphantsi.
Kwindandatho yokufa kwezinto ze-4Cr13, umthombo wayo womgangatho kufuneka uqale kwi-ingot: i-chemical composition (i-mass fraction%) ye-ring ring ye-4Cr13 steel is: Umxholo we-C ≤ 0.36 ~ 0.45, umxholo we-Cr 12 ~ 14, Umxholo we-Si ≤ 0.60, umxholo we-M ≤ 0.80, umxholo we-S ≤ 0.03, umxholo we-P ≤ 0.035; Ekusetyenzisweni kwangempela, ubomi benkonzo yendandatho bufa malunga ne-12% yomxholo we-Cr ingaphezulu kwe-1/3 emfutshane kunomnxeba wokufa kunye ne-14% ye-Cr umxholo phantsi kweemeko ezifanayo zolunye unyango; Ngoko ke umthombo ring die umgangatho ukusuka echibini steel. Akuyimfuneko kuphela ukuqinisekisa ukuba umxholo we-Cr ungaphezulu kwe-13%, kodwa nokuqinisekisa ukuba ubungakanani kunye nemilo iyahlangabezana neemfuno zokubumba.
