CCS FH40 steel phaj yog cov txheej txheem steel phaj rau siab - lub nkoj muaj zog thiab cov ntug dej hiav txwv. Qhov cuam tshuam kub ntawm CCS FH40 steel phaj yog - 60℃, thiab nws muaj qhov kub tsis zoo - qhov kub thiab txias ua haujlwm. Vim yog qhov nyuaj ntawm kev taug kev ib puag ncig ntawm cov nkoj loj, nws yog ib qho tsim nyog yuav tsum tau siv lub nkoj steel kom muaj qhov zoo toughness. Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig txias, nws yog ib qho tsim nyog yuav tsum muaj qhov zoo tshaj plaws qis- qhov kub thiab txias cuam tshuam rau kev laus, uas yuav tsum muaj qhov hloov pauv qis qis, uas kuj yog qhov tseem ceeb ntawm Chav Kawm F siab - lub zog nkoj daim hlau.
