PCR2W8V 1.2581 Kub Rolled Round Bar
PCCR2W8V Round Steel yog ib txwm siv tuag {{}} Casting pwm hlau. Nws muaj cov ntsiab lus roj teeb qis dua kom ntseeg tau tias qhov siab tawv thiab zoo thermal conductivity ntawm cov hlau. Nws tseem muaj ntau cov chromium ntau dua cov ntsiab uas tau yooj yim tsim cov carbides, yog li nws muaj zog dua thiab lub zog ntawm kev kub siab (ntawm 650 degree). Lub hardness tseem nyob ib puag ncig HB300) vim tias cov theem hloov kub ntawm cov hlau muaj siab, nws muaj cov cua sov thermal no tiv thaiv kev sib txawv thiab lub voj voog txias. Lub hardenability kuj zoo. Lub steel ntu thickness yog tsis pub dhau 100 mm thiab tuaj yeem ua kom tawv, tab sis nws cov tawv me thiab cov huv yog cov neeg pluag.
1.2581 round bar (x30wcrv9-3) siv tus qauv din eno 4957-2018 thiab muaj qhov zoo thermal stability thiab hnav tsis kam. Tom qab kev kho cua sov kom tsim nyog, lub hardness ntawm 1.2581 steel hloov bar tuaj yeem ncav cuag ib lub hardness ntawm 58 ~ 62hrc.
