30CrMnSiA kub dov steel ntawv

Alloy structural steel yog ib hom hlau uas yog siv los ua cov khoom siv kho tshuab thiab ntau yam engineering, uas muaj ib lossis ntau lub ntsiab lus alloy.
30CrMnSiA yog ib qho nruab nrab carbon nrog lub zog siab thiab tsis zoo vuam kev ua haujlwm.
30CrMnSiA muaj zog thiab txaus toughness tom qab quenching thiab tempering, thiab hardenability kuj zoo. Tom qab quenching thiab tempering, cov khoom yuav siv tau raws li ib tug sib tsoo log ncej, zog thiab sprockets.
30CrMnSiA muaj kev ua tau zoo, ua haujlwm me me deformation thiab qaug zog ua haujlwm. Rau cov ncej thiab piston qhov chaw thiab lwm yam. Nws yog siv ntau yam tshwj xeeb hnav xws li tsheb thiab dav hlau.
Cov khoom siv yog xim dub thiab galvanized tuaj yeem ntxiv kev zoo nkauj thiab xeb.
