Txhua cov ntaub ntawv hauv kev lag luam muaj keeb kwm ntev, tab sis niaj hnub no peb yog tham txog keeb kwm kev tsim kho ntawmAlloy Steel Zam Txim.
Los ntawm kev tsov rog hauv ntiaj teb thib ob mus rau 1960,Alloy Steel Zam TximTau tsuas yog lub sijhawm ntawm txoj kev txhim kho ntawm high-zog steel thiab ultra-high-zog hlau. Vim tias cov kev xav tau ntawm kev lag luam aviation thiab kev txhim kho cov hlau loj, xws li dej nag ntau-hluav taws xob cov hlau loj-muaj zog Puas yog nws tus sawv cev hlau qib.Amter Lub 1960, ntau yam tshiab metallurgical thev naus laus zis, tshwj xeeb tshaj yog cov cua sov ua kom zoo dua qub, tau hais tawm dav. Alloy steel tau pib txhim kho hauv kev coj ua ntawm siab huv, siab precision thiab ultra-cov roj carbon tsawg. Marages steel thiab ultra-ntshiab ferrite tau tshwm sim dua.New tus qhab nia steel xws li Stainless hlau.
