The iron oxide skin on surface of equivalent material of nm500 steel

S355J2 steel plate equivalent material of NM500 steel 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 equivalent material of NM500 steel 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℃.

equivalent material of NM500 steel, Steel pipes are widely used in our life, such as pipelines for transporting oil, natural gas, gas, water and some solid materials.
