Manganese steel plate is subdivided according to material grade: Q345A, Q345B, Q345C, Q345D, Q345E, A573 Grade 70 rolled structural steel. The main differences according to the classification are as follows: A needs no impact test, B needs room temperature impact test (20 degrees above zero), C needs zero degree impact test, D needs minus 20 degree impact test, and E needs minus 40 degree impact test. The most important characteristic of manganese steel plate is that under the condition of strong impact and extrusion, the surface layer rapidly hardens, but the core still maintains good toughness and plasticity, and the hardened layer has good wear resistance.
37SiMn2MoV steel is high-grade quenched and tempered steel. A573 Grade 70 rolled structural steel, 37SiMn2MoV steel has excellent comprehensive mechanical properties, good heat treatment process, good hardenability, low sensitivity to quenching crack, high resistance to tempering, very low temper brittleness, good high temperature strength and low temperature toughness. Chemical composition of 37SiMn2MoV steel: C: 0.33-0.39, Si: 0.60-0.90, Mn: 1.60-1.90, Mo 0.40-0.50, V: 0.05-0.12. After quenching and tempering, 37SiMn2MoV steel is usually used to manufacture heavy load and large section important parts.
In the past, A573 Grade 70 rolled structural steel, NM360 wear-resistant steel plates generally do not add tungsten. However, after adding the alloying element tungsten, the carbides distributed along the grain boundaries are greatly reduced, the acicular carbides in the crystal disappear, and there are a large number of granular carbides in the crystal. Tungsten reduces the precipitation of carbides and is spherically dispersed in the austenite crystals, which is beneficial to improve the strength and toughness of the NM360 wear-resistant steel plate.
