Q390B alloy steel phaj
Q390B siab zog steel phaj yog ib qho tsis tshua muaj alloy siab zog steel qauv. Tus qauv tseem ceeb yog GB / T 1591-2018 "Low Alloy High Strength Structural Steel". Nws muaj cov cuab yeej zoo txhua yam thiab kev ua haujlwm, thiab lub zog tawm los tsis tsawg dua 390MPa .
Cov khoom siv dav dav ntawm Q390B siab zog phaj yog tuab 8-150mm, dav 2000-2500mm, thiab ntev 6000-12000mm. Peb kuj tseem tuaj yeem nqa tawm yav tom ntej dov raws li cov neeg siv khoom xav tau.
Q390B qis alloy steel phaj muaj kev qaug zog zoo, siab tawv thiab vuam kev ua tau zoo, thiab yog siv dav hauv kev tsim kho, txuas hniav, tshuab tsim, tshuab hnyav, steel qauv, tsheb ciav hlau, tsheb tshwj xeeb thiab lwm yam haujlwm.
GNEE yog ib lub chaw tsim khoom ntawm huab cua steel phaj nrog 17 xyoo ntawm kev tsim khoom. Lub siab tensile steel phaj peb muab tau nruj me ntsis ua raws li cov qauv, dhau daim ntawv pov thawj zoo, tuaj yeem muab cov ntawv pov thawj zoo, thiab lees txais kev kuaj thib peb.
Peb tuaj yeem tsis tsuas yog muab lub zog siab qis alloy steel ntawm ntau qhov tshwj xeeb thiab qhov ntau thiab tsawg, tab sis kuj A709 Qib 50 qib steel, cov khoom zoo steel cov ntaub ntawv S355J2, S690QL1 siab yield zog steel. Tsis tas li ntawd, cov khoom uas peb muab tuaj yeem muab qhov loj me thiab ntau yam kev pabcuam raws li koj qhov kev xav tau kawg.
