NM400 steel specifications,The main advantage of 20CrMo alloy steel plate is reflected in its various physical and chemical properties. For 20CrMo alloy plate, the main component is alloy, and the physical and chemical properties of alloy are generally, a single metal is better, and its performance is stronger. The main features of 20CrMo alloy steel plate are high precision, rigidity, high temperature and high pressure resistance, not easy to corrode and other characteristics.

S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.NM400 steel specifications

NM400 steel specifications,Q345 and Q345B are steel numbers The differences are as follows:1 Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B2 Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃)3 Q345 does not indicate carbon content of steel; Q345B carbon content is 020%Q345 refers to carbon structural steel with yield point (σ s) of 345MPa The following letters indicate the quality level, including A, B, C, D and E,NM400 steel specifications.
