P265GH pressure vessel steel, Weathering steel plate is a kind of commonly used building materials with both functionality and aesthetics. Therefore, weathering steel has been widely used in the field of processing and decoration in the construction industry, and has been favored by many architects and landscape designers. Weathering steel has strong corrosion resistance and wear resistance. It not only has been applied in construction industry, but also have a wide range of applications in other fields.

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel p265gh pressure vessel steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the p265gh pressure vessel steel market and has strong competitiveness.

How to distinguish between hot rolled and cold rolled process?The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, p265gh pressure vessel steel, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.

Temperature has a great influence on the strength of the material, p265gh pressure vessel steel. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.

When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
