Kub Rolled Q690 HSLA Steel Phaj
Q690 yog hom tsis tshua muaj alloy siab- lub zog cov qauv hlau, uas muaj Q + tus lej + cov cim qib zoo + cov qauv deoxygenation cim.Tus "Q" hauv Q690 sawv cev rau qhov taw tes tawm ntawm cov hlau, thiab "690" qhia cov txiaj ntsig taw tes tus nqi hauv MPa.Piv txwv li, Q690D yog qhov kev ntxhov siab (9) qhia tias qhov kev ntxhov siab. qib yog D structural steel. Q690D qhia tias qhov kev ntxhov siab tawm los (σs) yog 690 MPa, thiab qib yog structural steel ntawm qib D. Cov qib siv feem ntau ntawm Q690 yog D thiab E. Qib Q690 kuj muaj nyob rau hauv cov qib hauv qab no.
