What is difference between 50crv4 and 51crv4 structural steel?
The company adheres to the management concept of "people-oriented, talent is concerned", develops business with the spirit of "believing strength, practical style, difference between 50crv4 and 51crv4 professional service and dare to compete", and provides customers with "professional, value-added and effective" service support. For the company's development and take-off, we work together to move forward and create a better difference between 50crv4 and 51crv4 tomorrow!
SA387Gr5Cl2 steel material is suitable for refining and gas treatment in hydrogenation and conversion equipment at high temperature. The maximum thickness of difference between 50crv4 and 51crv4, SA387Gr5Cl2 steel plate can reach 250mm. According to different thickness and impact requirements, the heat treatment of SA387Gr5Cl2 steel plate is normalizing plus tempering or normalizing plus rapid cooling plus tempering. By using special smelting method, the content of phosphorus is reduced so that sa387 has high brittleness resistance and good impact toughness at low temperature.
The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as difference between 50crv4 and 51crv4, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.
The microscopic strength of the difference between 50crv4 and 51crv4, wear-resistant steel plate refers to the strength of the hard phase, but the higher the strength, the higher the wear resistance. Strength is the basis of high-quality wear resistance of wear-resistant steel plates, but the relationship between strength and wear resistance is not proportional; wear-resistant steel plates are often wear-resistant, the root cause is that there are hard particles and soft conventions.
