Pob qauv qauv
Cov kabmob pob yog feem ntau muaj plaub qhov yooj yim: pob, ntiv nplhaib sab hauv, ntiv nplhaib sab nraud thiab seem tuav hu ua lub tawb lossis cov khaws cia. Kev lag luam dav npas kabmob tau raws li AISI 52100 tus qauv. Cov pob thiab cov nplhaib feem ntau yog ua los ntawm siab chrome steel nrog Rockwell C-nplai tawv ntawm nruab nrab ntawm 61 thiab 65. Lub hardness ntawm tus khaws tau qis dua li ntawm cov pob thiab lub nplhaib, thiab cov khoom siv yog hlau (xws li: carbon nruab nrab steel, aluminium alloy) lossis tsis muaj hlau (xws li: Teflon, PTEF, cov khoom siv polymer). Cov kabmob pob tau muaj kev sib hloov tig qis dua li cov kabmob phau ntawv sau, yog li kev sib txhuam ua rau kub qis ntawm tib lub nrawm.
