Size effect for Q345B carbon steel plate sheet

Low-alloy structural steel plates are mainly used in machinery manufacturing and metal structural parts. Advantages of Q345B carbon steel plate sheet, low-alloy structural steel plates: They have superior performance and light weight. Disadvantages of low-alloy structural steel plates: These steel plates are all killed plates. The molten steel is deoxidized before the production. When the molten steel is poured into the ingot mold, its reaction is relatively calm and there will be no boiling state. Q345B carbon steel plate sheet, low-alloy structural steel plates price will be more expensive.

Q345B carbon steel plate sheet controlled rolling is that, on the basis of adjusting the chemical composition of Q345B carbon steel plate sheet, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of Q345B carbon steel plate sheet.

Superior process production line advantage sdf: The company has focused on weathering steel Q345B carbon steel plate sheet, pressure vessel plate, oil tank plate, pipeline steel plates, and steel welded structures for many years, and has a strong factory scale; one of the domestic excellent weathering steel manufacturers, serving customers all over the world; using frequency conversion and microcomputer program control, the equipment is highly automated; Improve product efficiency and improve product quality.

Application of medium and thick plates: Medium and thick plates are used for construction engineering, machinery manufacturing, shipbuilding, bridge construction, etc. Medium and thick plates Q345B carbon steel plate sheet can also be used to manufacture various containers, furnace shells, furnace plates, some parts of tractors and welding components. Medium and thick plates are usually in form of bridges and automobile static steel plates, low alloy steel plates, shipbuilding steel plates, boiler steel plates, pressure vessel steel plates, checkered steel plates, automobile girder steel plates, etc.
