The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel A514 grade P alloy steel plate 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 A514 grade P alloy steel plate market and has strong competitiveness.
For the selection of A514 grade P alloy steel plate, automobile steel plate products and manufacturers, we should not only check the material processing quality, but also check how the actual installation and use effect are. The comfort, bearing capacity and other indicators of the auto made of the automobile steel plates should also be considered. In addition, in choosing A514 grade P alloy steel plate, automobile steel plate manufacturers and products, it is better to find a few more companies to compare, and conclude to choose a more suitable automobile steel plate manufacturer.
Compared with A514 grade P alloy steel plate, boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.
Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of A514 grade P alloy steel plate etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in A514 grade P alloy steel plate etc. steel is strictly controlled.
