M42 cuab yeej steel yog high-speed steel nrog high cobalt. Thiab nws tseem hu ua JIS SKH59 thiab DIN 1.3247 steel. Nws yog tsuas yog siv rau siab toughness precision, hnav-resistant hardware, txias stamping tuag thiab tej cuab yeej. Nws muaj qhov toughness siab thiab hardness tuaj yeem ncav cuag 70HRC. Nws kub hardness yog siab thiab yooj yim rau grind thiab txiav. Cov cuab yeej txiav uas yog ua los ntawm M42 steel tuaj yeem txiav cov cam khwb cia superalloys, titanium alloys, thiab ultra-high-strength steels. Nws yog siv dav los tsim cov cuab yeej siab precision thiab nyuaj txiav vim nws cov khoom sib tsoo zoo. M42 Steel round bar ntawv plateproperties thiab tshuaj muaj pes tsawg leeg raws li hauv qab no.
