S420M S460M HSLA Steel Plate
S420M is thermomechanically rolled weldable fine grain structural steel, flat rolled material with a thickness of not more than 120 mm. S420 is a non-alloy structural steel, S420M steel trademark consists of the following parts: Symbol letter S: Structural steel related to the thickness of less than 16 mm yield strength value: not less than 420, M stands for the status of his delivery, that is, thermomechanically rolled means that the rules in the temperature of not Below -50 degrees when the impact of the capital letter L marked.
S460M high strength low alloy steel plate is the European standard thermomechanically rolled weldable fine grain structural steel plate, S460M grade "S" indicates that the steel is structural steel, "460" indicates that the steel in the thickness of less than or equal to the minimum yield strength of 16mm 460Mpa, "M" indicates that the steel in the thickness of less than or equal to the minimum yield strength of 16mm. "S460 steel is divided into two levels according to the different impact, respectively: the temperature is not less than -20 ℃ when the minimum value of impact work specified with M, that is, S460M; the temperature is not less than -50 ℃ when the minimum value of impact work specified with ML, that is, S460ML.
