Zonke izinto ezikushishino zinembali ende, kodwa namhlanje sithetha ikakhulu malunga nophuhliso lwembalii-alloy steel forgings.
Ukususela kwimfazwe yehlabathi yesibini ukuya koo-1960,i-alloy steel forgingsngokuyininzi ixesha lophuhliso lwentsimbi ephezulu kunye ne-ultra-high-strength steel. Ngenxa yeemfuno kushishino lweenqwelomoya kunye nophuhliso lobugcisa rocket, iintsimbi ezininzi ezintsha-amandla aphezulu kunye neentsimbi ultra-high-amandla aveleSteel amabakala, ezifana imvula ukuqina high-amandla intsimbi stainless kunye ezahlukeneyo ezisezantsi-alloy high-ukuqina steels, ngabameli bayo intsimbi grade.Emva kweminyaka yoo-1960, ngakumbi metalnologies ezintsha ezininzi, technologies ezintsha, ingakumbi metalnologies olutsha, ezininzi zentsimbi, intsimbi, iintsimbi eziziintloko. itekhnoloji yokucoca ngaphandle kwesithando somlilo, yamkelwa ngokubanzi. Intsimbi ye-alloy yaqala ukuphuhlisa kwicala lokucoceka okuphezulu, ukuchaneka okuphezulu kunye ne-ultra-low carbon. Intsimbi ye-Maraging kunye ne-ultra-pure ferrite yavela kwakhona.Amabanga amatsha entsimbi afana nentsimbi engatyiwa.
