75Cr1 alloy cuab yeej steel Cov lus qhia ntxaws
75Cr1 yog tus qauv txawv teb chaws txias ua hauj lwm cov cuab yeej steel hlau, feem ntau siv los tsim cov cuab yeej me me, xws li: mandrel, punch, ramming cov cuab yeej, rab chais thiab lwm yam.
Cov teeb meem hauv qab no tuaj yeem tshwm sim hauv kev siv 75Cr1 alloy cov cuab yeej hlau
Tshuaj muaj pes tsawg leeg: {{0}}.2 ~ 0.78%C,0.25 ~ 0.5{{10}} %Si,0.5 ~ 0.8%Mn; 0.3 ~ 0.4% Cr, P Tsawg dua lossis sib npaug li 0.035%, S Tsawg dua lossis sib npaug li 0.035%, yog cov cuab yeej ua haujlwm txias,
Pom zoo annealing kub: 700 ~ 720 degree, hardness tom qab annealing 200HBS, yuav tsum yog ib tug spheroidizing annealing txheej txheem, qhov tseeb ntau lawm kub yuav tsum tau kho rau 720 degree cua sov!
Lub ntsiab tsis zoo ntawm 75Cr1 alloy hlau yog raws li nram no
