The domestic material corresponding to ST52 is Q345.
Specifically, ST52 is equivalent to the domestic grade Q345 (also known as 16mn). In addition, ST52 also corresponds to Q345C in the national standard GB1591-94. The new material number is 1.0570 and the old material number is 1.0841. You can refer to DIN 17100 and GB1591 standards for comparison.

1. Introduction to ST52-3 steel plate materials:
ST52-3 is equivalent to the domestic grade Q345, (16mn) St52-3 new material number: 1.0570, old material number: 1.0841. St52-3 has its tensile strength and yield point as its main characteristics. St52-3 is a low-alloy high-strength steel. The steel number is composed of St, the characteristic value of the steel and the quality index. It is a steel type that has selected deoxidation methods. The corresponding mark (U or R) is placed in front of the steel number for special purposes. Steels such as: USt52-3 or RRSt37-2. ST52-3 steel plate corresponds to national standard Q355, analysis of yield tensile properties of ST52-3.

ST52-3 steel plate belongs to the German standard low alloy steel, which implements the standard DIN17100. The materials under the DIN standard are: ST37-2, STE355, STE460, etc. ST52-3 steel plate heat treatment: hot rolling, controlled rolling, normalizing.
ST52-3 steel plate complies with the technical standard DIN17100, and its performance is close to the national standard Q355B.
