The main difference is that P500Q steel has a lower minimum yield strength (500 MPa) compared to P690Q (>690 MPa), uas tseem ua rau qis qis qis zog tensile rau P500Q. Ob leeg yog quenched thiab tempered steel phaj rau cov hlab ntsha siab, ua raws li EN 10028-6 tus qauv, tab sis P690Q yog qib siab zog.
