Hnav steel yog smelted nrog cov tshuab hluav taws xob lossis hloov kho hluav taws xob, thiab cov khoom lag luam tsis ntev los no, cov khoom siv kub xws li forging thiab dov tau nce zuj zus. Txoj kev ntau lawm ntawm cov kev hnav-resistant steel qhov uas siv feem ntau ntawm cov txheej txheem kev kho cua sov lossis cov txheej txheem kev kho kom sov kom tau raws li cov kev xav tau ntawm kev ua kom pom kev tsis kam. Rau cov steel qhov uas uas nws sib tw ua suab nrov tseem ceeb cuam tshuam, kev ntsuas tsim nyog yuav tsum tau ua, thiab txwv kev ntsuas yuav tsum tau muab tso rau pem hauv ntej rau cov kev phom sij thiab roj av. Ntxiv nrog rau kev kawm tiav, tus lej, cov duab thiab kev kho kom haum rau kev ua kom tau cov tshuaj tiv thaiv kev ua kom tau los ntawm cov khoom siv sib xyaw ntawm cov hlau me.
