ST70-2 steel's Mechanical properties is Yield strength more than 365MPa, tensile strength 690-900Mpa.ST70-2 steel is mainly used for riveting, bolting, welding purposes. Structural Steels like ST70-2 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.
