AR400 steel phaj yog cov khoom hnav-tiv taus paub txog nws qhov siab tawv thiab tawv, nrog rau qhov nyuaj ntawm 360 txog 444 Brinell hardness. Qhov tshwj xeeb steel phaj no yog tsim los tiv thaiv kev hnav thiab kev cuam tshuam hauv kev xav tau daim ntawv thov uas cov khoom raug cuam tshuam rau kev hnav hnyav.
Brinell hardness ranges los ntawm 360-444, qhia lub phaj steel lub peev xwm los tiv thaiv deformation thiab indentation nyob rau hauv cov ntaub ntawv loads. AR400 steel feem ntau yog siv rau hauv kev lag luam xws li mining, kev tsim kho, kev tsim khoom thiab kev tuav cov khoom uas hnav tsis kam yog qhov tseem ceeb.
Qhov tshwj xeeb hardness ntawm AR400 steel zoo tiv thaiv hnav thiab txuas ntxiv lub neej ntawm cov tshuab, khoom siv thiab cov qauv raug rau qhov chaw hnyav. Los ntawm kev muab kev hnav zoo tshaj plaws, AR400 steel phaj pab txo cov nqi tu thiab txhim kho cov khoom siv ua haujlwm ntev, ua rau nws muaj kev ntseeg siab rau cov ntawv thov uas xav tau kev tiv thaiv kev hnav zoo.
