", based on customer requirements and combined with actual production conditions, using data analysis, organized technical staff of various departments. Enterprise standards and internal control standards are approved for publication after full discussion and approval.
This product is mainly used in boilers and pressure vessels. Boiler pressure vessel plates
are used to manufacture various boilers and important accessories. Because the boiler steel plate is working at a medium temperature (below 350 °C) high pressure, in addition to high pressure, it is also subject to Impact, fatigue load and water and gas corrosion require a certain strength and good welding and cold bending performance. The steel plates for boilers and pressure vessels produced by Maanshan Iron & Steel Co., Ltd. not only have the strength, plasticity and impact performance reaching the international advanced standard level, but the S and P contents are low, and the surface quality is good, the difference in the same plate thickness is small, the size is accurate, the delivery is fixed, and the after-sales service is provided. Passionate and thoughtful. Its comprehensive performance has reached the international advanced level.
