St 50-2 is a kind of common structure carbon steel plate which is under DIN17100 standard,we can regard St 50-2 steel plate as common carbon structural steel,St 50-2 steel’s Mechanical properties is Yield strength more than 295MPa, tensile strength 490-660Mpa.
St 50-2 is a type of steel sheet under DIN standard which is used to build ship, bridge, belongs to high strength sheet.Structural Steels like St 50-2 is used in many applications, combining good welding properties with guaranteed strengths. There are many grades and the uses varied including civil and industrial engineering. High strength low alloys have replaced many structural steels where weight reduction is important (e.g. automotive) but with guaranteed strengths.
