Boiler steel plate is mainly used in the manufacture of various boilers and important accessories. Since the boiler steel plate works at medium temperature (below 350°C) and high pressure, in addition to high pressure, it is also subject to impact, fatigue load and water vapor corrosion. It is required to guarantee a certain strength, and has good welding and cold bending performance.
