Khoom Description
Q235 steelyog ib tug dawb carbon structural steel uas yog dav siv nyob rau hauv Tuam Tshoj. Q235 cov khoom hauv Suav tus qauv GB / T 700 muab faib ua 4 qib zoo:Q235A, Q235B, Q235C thiab Q235D; Qhov ceev ntawm cov hlau no yog 7.85 g / cm3 (0.284 lb/in3), tensile zog yog 370-500 MPa (54-73 ksi); yield zog yog 235 MPa (34 ksi) rau steel bar txoj kab uas hla los yog phaj thickness Tsawg tshaj los yog sib npaug zos rau 16 hli. Txij li nws yog cov hlau me me, cov khoom siv feem ntau siv ncaj qha yam tsis muaj kev kho cua sov. Cov khoom siv Q235 muaj lub zog nruab nrab, nyob rau hauv cov ntaub ntawv ntawm lub zog siab dua, Q275 lossis siab zog qis alloy qauv steel Q355 (yav tas los Q345) tuaj yeem xaiv.
