S420ML STEEL PLATE,EN10025-4 S420ML
Source：Yusheng steel
Under Europe standard EN 10025_4, steel plate S420ML shall be rolled under thermomechanical,and be done
low temperature impacting test at minus 50 centi degree with minimum 27J on longitudinal V_notch test
pieces for thermomechanical rolled steel S420ML.
If customers also accept the impacting test on transverse direction,the impacting energy value shall be
above 16J.Now Yusheng Industrial just list the chemical composition for ladle analysis and Mechnical
properites for S420ML as belows:
