Q690 High Strength Steel Phaj
High tensile steel ntawv Khoom Taw qhia
Q690 hsla steel yog ib hom uas tsis tshua muaj alloy siab zog steel qauv. Q690 siab zog qis alloy qib qhia: "Q" sawv cev rau lub zog tawm los, "690" sawv cev rau lub zog ntawm cov hlau yog 690 MPa. Q690 qis alloy steel tsis tsuas yog muaj lub zog siab, Nws kuj yog nyob rau hauv qeb ntawm cov pa roj carbon tsawg.
Q690 hsla structural steel cov ntaub ntawv tau muab faib ua ntau qib zoo, suav nrog Q690C siab zog qis alloy steel ntawv, Q690D hsla steel ntawv thiab Q690E siab zog alloy steel. Ntawm lawv, "M" stands rau "TMCP" (thermo-mechanically tswj kev ua), uas qhia tau hais tias Q690 siab tensile steel yog quenched thiab tempered steel nrog zoo kub tsis tshua muaj zog thiab muaj zog toughness.
Hlau daim hlau ua los ntawm Q690 siab zog uas tsis muaj alloy hsla steel khoom yog dav siv nyob rau hauv thee mining machinery, engineering machinery, heavy-duty tsheb, txuas hniav thiab siab hlab ntsha daim hlau vim lawv siab yield zog thiab tensile zog.
Raws li cov hlau ua tau zoo, Q690 cov hlau tsis tshua muaj hlau muaj cov ntawv thov dav dav thiab qhov zoo hauv ntau qhov chaw. Q690 qis alloy cov qauv hlau muaj cov khoom siv zoo heev, kev tiv thaiv corrosion thiab kev ua haujlwm uas tuaj yeem ua tau raws li qhov xav tau ntawm ntau qhov chaw ib puag ncig. Cov kev cai nruj heev muab kev txhawb nqa tseem ceeb thiab lav rau kev txhim kho ntau yam kev lag luam.
