EN 10025-4 S355ML steel plate is a hot-rolled weldable fine-grained structural steel. S is the meaning of structural steel, 355 indicates that the small yield value of the relevant thickness less than 16mm is 355MPa, and M represents his delivery, that is, the meaning of hot rolling. The rule is when the temperature is not less than -50 degrees. The impact is indicated by a capital letter L.
EN 10025-4: 2004 standard specifies requirements for flat and long products of hot rolled weldable fine grain structural steels in the thermomechanical rolled condition. The grade S355ML steel specification: in thickness ≤120 mm for flat products and in thickness ≤150 mm for long products.
