S355K2 STEEL PLATE

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 S355K2,S355K2 steel plate,S355K2 steel sheet,the impacting test temperature shall be the same as steel plate S355J2 (both minus 20 centigree),however,S355K2 stel plate need a higher average impacting energy when doing test.
