Looking to the future, our company will make its main business more competitive while carrying out diversified, extensive, green and harmonious development modes, so as to be the most competitive A514 grade E QT steel plate producer in the world as well as a worldwide first-class enterprise. With ten years cooperation with these big mills, now we are the agent of super stainless steel mills in China.
What should be paid attention to when using A514 grade E QT steel plate, carbon steel? First, the strength level of carbon steel is low and it is easy to fracture, so carbon steel is not suitable for high strength engineering. Second, the heat-resistant performance of carbon steel is relatively poor, which can not be applied in the long-term high-temperature fields such as boilers. Third, the carbon steel is extremely easy to rust, so it is not suitable for water transport projects. Therefore, the use of carbon steel depends on the use of the environment, if it is harsh conditions, it is better to choose other steel materials.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the A514 grade E QT steel plate steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This A514 grade E QT steel plate method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
