Cov kabmob hlau muaj lub siab hardness, tensile lub zog, hu rau qaug zog lub zog thiab hnav tsis kam, thiab muaj qhov muaj zog tawv, uas ua tau raws li qhov yuav tsum tau ua rau corrosion tsis kam thiab siab kub tsis kam ua raws qee yam.
Lub siab cov roj carbon chromium cov hlau muaj cov pa roj carbon ntau ntawm cov ntsiab lus (0.95-1.05%), lub siab thiab teeb tsa tsis sib txig tau tuaj yeem tau txais tom qab quenching, thiab lub neej ntev ntev. Qhov tsis zoo yog tias nws me ntsis tsis kam tiv thaiv rau cov nra hnyav thiab cuam tshuam toughness.
High-carbon chromium bearing steel yog tsuas yog siv raws li cov nplhaib thiab dov ntawm cov dov ntawm cov kabmob uas muaj nyob rau hauv cov xwm txheej dav dav ntawm kev siv.
Cov kabmob steel npas, ua qhov tseem ceeb ntawm cov kabmob, ua lub luag haujlwm tseem ceeb heev.
Yog li ntawd, kev siv cov txiaj ntsig thiab kev pab cuam lub neej ntawm cov kabmob tau ze rau qhov tseeb thiab qhov nyuaj ntawm cov kabmob pob steel. Lub hardness ntawm cov kabmob pob steel yog cuam tshuam nrog crushing nqi tus nqi ntawm lub npas steel.

Qhov loj tshaj plaws ntawm tus kabmob steel pob yog nws lub siab hardness thiab hnav tsis kam. Tom qab ntawd peb yuav tsum tau qhia kom nquag pom txog qhov nyuaj ntawm tus nqi ntawm lub pob steel. Lub hardness tus nqi ntau ntawm cov tiav pob steel tau teev nyob rau hauv lub teb chaws tus qauv ntawm pob steel GB / T 308.1-2013.
<30mm, HRC = 61-66;
30MM – 50MM, HRC = 59-64;
> 50MM, HRC = 58-64;
Tom qab tau ntxuav, ua kom tiav roj & ua ntej pob cov qauv pob los ntawm cov pob xa mus rau qhov kev tshuaj xyuas zaum kawg kom kuaj rau qhov saum npoo ntawm qhov chaw, puas ncig, waviness, ntau qhov sib txawv thiab qhov nyuaj nyob hauv lub chaw kuaj mob nruj, raws li cov kev cai tswj kav thiab kos cov txheej txheem tshawb. Thaum txhua yam ua tau tiav lawm, daim ntawv pov thawj kev xeem raug npaj rau cov neeg siv khoom. Peb lub chaw kuaj ua haujlwm yog nruab nrog qhov ntsuas siab, cov cav thoob ntiaj teb thiab cov cuab yeej siv thiab raug tswj hwm los ntawm kev cob qhia thiab cov neeg ua haujlwm tsim nyog.
