Taw qhia rau cov ntawv thov ntawm Q690E steel phaj
Q690E steel phaj yog lub siab- Lub zog quenched thiab tempered steel phaj nrog} 40 feeb rau cov European cov qauv S690QL. Nws yog siv nyob rau hauv kev tsim khoom ntawm ntau hom kev tsim ntau hom kev ua tshuab hluav taws xob, cov tsheb hluav taws xob, cov roj hluav taws xob, thiab lwm cov cuab yeej siv kho tshuab thiab cov txheej txheem neeg kho mob.
Q690E Cov phaj steel tsis tsuas yog muaj lub zog siab thiab muaj zog tiv thaiv, kev ua kom muaj zog, thiab kev ua kom muaj zog, muab cov khoom muaj txiaj ntsig zoo. Thaum lub sijhawm thov, nws cov kev ua tau zoo tau ua kev ua tau zoo sib xws thiab lees paub los ntawm kev tsim kev lag luam. Vim tias qhov kev lees paub dav no, nquag siv hauv kev tsim khoom, thiab txhim kho cov khoom siv steel tau maj mam dhau los ua ib qho ntawm cov hlau qib siv hauv Suav teb.
Lus Taw Qhia Txog Qib Kev Kawm ntawm Q690E Hlau Phaj
Nyob rau qib Q690E:
"Q" denotes muab lub zog.
"690" qhia tau cov paib muaj zog ntawm cov hlau phaj hauv MPA.
"E" sawv cev rau qib kawm, qhia txog kev cuam tshuam nyuaj ntawm -40 degree.
Q690e steel phaj nyeem tau nyeem raws li "Q rau-}} {2 {xoom e".
Q690 Steel phaj series muaj qib peb:
Q690C: Kev Cuam Tshuam Toughness ntawm 0 Qib
Q690D: Qhov Kev Cuam Tshuam Cov Mob Ntawm -20 Qib
Q690E: Qhov Kev Cuam Tshuam Cov Mob Ntawm -40 Qib
