S275JR carbon steel material,The company has allocated special environmental protection facilities for all pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, steel mill scale, environmental protection dust has reached 100%,S275JR carbon steel material.

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.

S275JR carbon steel material,Q345B material is a low carbon alloy steel grade with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability Q345 serues steel is widely used in bridges, vehicles, ships, buildings, pressure vessels Q represents the yield of this material, and the number 345 refers to the yield value of this material, which is around 345MPa As the thickness of the material increases, its yield value decreases,S275JR carbon steel material.
