P20 steel round bar ntawv phaj muaj ntau yam zoo heev. Nyob rau hauv cov xwm txheej pre-hardened, cov pwm tuaj yeem ua tiav yam tsis muaj kev kho cua sov. Uas txo lub sij hawm khiav thiab txhim kho efficiency. Tom qab nws tau ua tiav los ntawm forged, 1.2311 steel ua ntom. Tom qab ntawd nws tuaj yeem dhau 100 feem pua ntawm kev kuaj ultrasonic. Thiab tom qab qhov kev sim, yuav tsis muaj qhov pores tshuav thiab tsis muaj qhov tsis xws luag. Thiab nws tseem hu ua DIN 1.2311 thiab SCM4 steel. P20 cuab yeej steel tshuaj muaj pes tsawg leeg thiab cov ntaub ntawv ntau ntxiv raws li hauv qab no
