S460Q siab - lub zog steel phaj, tseem hu uaS460Q siab - muaj zog tsawg -} alloy steel phaj, ntog hauv qabEN 10025-6Tus qauv, uas siv rau kub - rolled qauv qauv hlau hauv quenched thiab tempered mob. S460Q steel daim hlau muaj cov txiaj ntsig zoo zog (Ntau dua los yog sib npaug rau 460 MPa) thiab siab tensile lub zog (550-720 mpa), muab kev ua tau zoo rau ntau load - cov kabmob qauv.
Lub sij hawm quenching cuam tshuam cov ferrous steel phaj sai dua li tseem cua txias, uas nce lub zog ntawm cov hlau. Qhov no yog ua raws li los ntawm kev kub ntxhov sov kom ua tau zoo dua qub thiab ductility, nqa cov hlau cov khoom siv tag nrho rau qib xav tau.
S460Q Daim Phiaj Tseem Yav Toj Tom Qab ATsawg - kub cuam tshuam xeem nyob rau -20 degree, txhawm rau txhawm rau muaj kev cuam tshuam zoo heev (Ntau dua los yog sib npaug rau 30 j) nyob rau hauv cov mob khaub thuas. Tsis tas li ntawd, nws cov ntsiab lus carbon qis (kwv yees li 0.20%) thiab ua kom haum rau welded alloy muaj kev sib xyaw ua ke, cranes, thiab lwm yam siab- lub zog engineering cov.
Cov qhov ntev ntev suav nrogThickness 6-150 mm, Dav 1500-4050 Hli, thiab ntev 3000 HliCov. Nrog cov neeg kho tshuab cov khoom siv thiab cov phiaj xwm sab hauv, s460Q hlau daim hlau tau dav siv nyob rau hauvTxuas hniav, lub tsev qauv qauv, cov tshuab hnyav, thiab khoom thauj, qhov twg siab load -}}}}}} Cov kabmob kev ua tau zoo thiab kev cia siab yog qhov yuav tsum tau ua.
