DC56D + Z cov khoom siv
DC56D + Z yog txias-kuav los tiag steel phaj, nws cov tshuaj muaj pes tsawg leeg yog hlau thiab carbon, tom qab sib txawv alloying kev kho mob, cov ntaub ntawv uas sib txawv zog yuav tau. Nws lub ntsiab chemical muaj pes tsawg leeg (feem feem ntau) yog: carbon 0.50% ~ 0.60%, silicon 0.1{{ 15}}% ~ 0.40%, manganese 0.70% ~ 1.10%, phosphorus Tsawg dua lossis sib npaug li 0.20%, sulfur Tsawg dua lossis sib npaug ntawm 0.03%, aluminium Tsawg dua lossis sib npaug rau 0.02%, titanium Tsawg dua lossis sib npaug 0.03%, boron Tsawg dua lossis sib npaug 0.003%.
DC56D + Z muaj cov cuab yeej zoo heev. Nws lub zog tensile feem ntau yog nyob nruab nrab ntawm 450 thiab 600 MPa, nws hardness yog nruab nrab ntawm 85 thiab 125 HRB, thiab nws elongation yog ntau dua los yog sib npaug rau 38%. Los ntawm cov txheej txheem sib txawv, xws li alloying, dov, annealing, thiab lwm yam, DC56D + Z tuaj yeem tau txais cov khoom sib txawv thiab kev siv.
DC56D + Z muaj corrosion kuj zoo. Vim tias muaj zaj duab xis tuab ntawm nws cov nplaim dej ruaj ruaj rau hauv cov huab cua thiab corrosive kev tshaj tawm, uas ua rau nws muaj zoo corrosion tsis kam. Tsis tas li ntawd, DC56D + Z kuj muaj huab cua tsis zoo thiab qaug zog, thiab tuaj yeem siv rau ntau qhov chaw hnyav.
Kev siv tseem ceeb ntawm DC56D + Z
DC56D + Z muaj ntau yam kev siv hauv tsheb, khoom siv hluav taws xob, hluav taws xob thiab lwm yam haujlwm.
Hauv kev tsim tsheb, DC56D + Z tau siv dav hauv kev tsim cov khoom siv tseem ceeb xws li lub cev tsheb, tsheb thauj mus los, thiab cov ncej. Vim nws lub zog siab thiab zoo corrosion kuj, DC56D + Z tuaj yeem txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm lub tsheb. Nyob rau tib lub sijhawm, vim nws qhov kev ua tau zoo heev, nws tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm stamping, vuam thiab lwm yam txheej txheem hauv kev tsim tsheb.
Hauv kev lag luam ntawm cov khoom siv hluav taws xob, DC56D + Z yog dav siv nyob rau hauv kev tsim khoom ntawm ntau yam keyboards, sockets, hlau vaj tse thiab lwm yam khoom siv hluav taws xob. Vim nws cov conductivity zoo, muaj zog corrosion kuj thiab yooj yim ua, DC56D + Z tau dhau los ua ib qho ntawm cov khoom siv zoo tshaj plaws hauv kev tsim khoom siv hluav taws xob. Tsis tas li ntawd, DC56D + Z kuj tseem siv tau los tsim ntau yam khoom siv hluav taws xob hauv tsev thiab cov khoom siv, xws li cov laug cam, coil skeletons, thiab lwm yam.
