Qhov sib txawv tseem ceeb yog tias P690QH yog European tus qauv tsim rau cov qib tshwj xeeb ntawm cov hlau (EN 1.8880), thaum P690Q yog hais txog qhov dav EN (European Standard) tsim rau quenched thiab tempered steels nrog lub nominal yield zog ntawm 690 MPa. P690QH tshwj xeeb yog ua tau raws li qhov yuav tsum tau ua rau cov thawv ntim khoom, suav nrog kev kuaj pom qhov tsis haum thiab tuab - kev coj ua haujlwm.
