High Strength Low Alloy Structural Steel Phaj
Qhov tshwj xeeb tshaj plaws ntawm cov hlau tsis tshua muaj zog hlau yog lawv lub zog siab. Nyob rau hauv lub kub dov los yog normalized mob, tsis tshua muaj hlau alloy siab zog steel feem ntau yog 30% mus rau 50% muaj zog tshaj cov coj carbon engineering structural steel. Yog li ntawd, lawv muaj peev xwm tiv taus cov khoom loj.
Peb lub tuam txhab tuaj yeem muab suav nrog: Q355, Q390, Q420, Q460, Q500, Q550, Q620, Q690, thiab lwm yam. Hauv kab lus no, kuv yuav qhia Q690 siab zog qis alloy hsla steel phaj.
Q690 yog cov hlau tsis tshua muaj siab- lub zog steel qauv, los ntawm Q + tus lej + cov cim qib zoo + cov cim deoxidation. Q690 nyob rau hauv "Q", sawv cev ntawm cov ntsiab lus ntawm cov hlau, "690" sawv cev rau cov txiaj ntsig taw tes tus nqi hauv MPa. Piv txwv li, Q690D sawv cev rau qhov kev ntxhov siab ntawm cov hlau, qhov taw tes tawm ntawm cov hlau, cov txiaj ntsig taw tes tus nqi, chav tsev yog MPa. Q690D qhia tias qhov kev ntxhov siab (σs) yog 690 MPa, qib D cov qauv hlau. Q690 feem ntau siv qib yog D, E qib.
