S460 steel shot surface treatment

S355J2 steel plate S460 steel shot 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 S460 steel shot 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℃.

X56 steel plate is a kind of steel mainly used for large-diameter pipelines. API X56 steel plate is used to manufacture buried pipelines for natural gas transmission. Due to the corrosion of soil, serious degradation will occur. The corrosion type of X56 steel plate that can be produced is usually general corrosion and pitting. we are API 5L X56 steel suppliers ,we also can supply API 5L X52,API 5L X60,API 5L X65,API 5L X70,API 5L X80,please contact us if you need.
