Q345qC steel plate is the steel plate of bridge structure, the implementation standard is GB / T 714-2015 standard. P235GH steel used for power plants, Q345qC-Z25 steel: Q represents the yield strength, 345 represents the small yield strength, the unit is MPa, q is short for the bridge, C quality grade, corresponding to the corresponding impact temperature and impact work value, Z is the Z-direction performance that is the performance of the steel plate thickness direction, Z25 is the Z-direction Performance level requirements.

The company always adheres to the p235gh steel used for power plants principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great p235gh steel used for power plants cause. Customers are welcome to visit our company at any time. We are always ready to support you.

The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for p235gh steel used for power plants pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common p235gh steel used for power plants carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.

After adding trace elements such as phosphorus, copper, chromium, and nickel to Q355NH steel, a dense and highly adherent protective film is formed on the surface of the weathering steel, which prevents rust from spreading and developing, and protects the substrate under the rust layer to slow its corrosion . An amorphous spinel oxide layer of about 50 μm to 100 μm thick formed between the rust layer and the substrate is dense and has good adhesion to the base metal, which greatly improves the atmospheric corrosion resistance of the steel material, p235gh steel used for power plants.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
