Ib qho ntawm peb cov neeg siv khoom, James los ntawm Canada, xa peb cov lus nug txog 42crmo4 alloy ca steel. Raws li lub sijhawm luv luv, nws yuav tsum tau txais cov 18 tons ntawm 42crmo4 steel hauv 45 hnub. Qhov ntawd tsis yog teeb meem rau peb vim tias peb khaws cov khoom muag txhua hnub ntawm 1,500 tons.
Tom qab tus neeg siv khoom tso nws daim ntawv xaj, peb tau npaj nws 42crmo4 steel npaj rau lub lim tiam no. Peb kuj pab cov neeg siv khoom kom pom qhov xa khoom sai tshaj plaws thiab cov khoom xa tuaj rau cov neeg siv khoom hauv 45 hnub.
