■ Overview
For S355 series in EN 10025-2,there are steel grades S355JR,S355J0,S355J2 and S355K2 steel plates owning to the different impacting test temperature and impacting enegy values.For steel plate S355K2,the impacting test temperature shall be the same as steel plate S355J2 (both minus 20 centigree),however,S355K2 need a higher average impacting energy when doing test.
