SA573 structural steel Grade 65 plate online and so on medium and heavy plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on fields. The surface quality problems of medium and heavy plates not only affect the appearance of the products, but also reduce the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate. Therefore, the medium and heavy plates manufacturers and users attach great importance to it. The surface quality of medium and heavy plate mainly refers to the surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plates.
It is easy to confuse ship plate with ordinary steel plate. What are the differences between ship plate and ordinary steel plate? First, compared with the ordinary steel plate, the thickness of the ship plate is thicker and the accuracy is better. Otherwise, it will be broken by the impact of sea water during the operation, which will bring life danger to the personnel on the ship. Second, compared with ordinary steel plate, SA573 structural steel Grade 65 plate online, the corrosion resistance of ship plate is more outstanding. The ship is immersed in sea water for a long time, if it does not have good corrosion resistance, then the ship plate will rust easily, and the weight of the ship will become larger, and it will also bring pollution to the sea water and cause ecological damage.
SA573 structural steel Grade 65 plate online annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of SA573 structural steel Grade 65 plate online annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. SA573 structural steel Grade 65 plate online annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
The company has sufficient stocks and complete specifications.
