SG295 steel plate is a kind of high quality carbon orange structure steel and low alloy structure steel used to manufacture liquefied petroleum gas cylinder and acetylene gas cylinder. With the wide application of gas cylinder steel, more and manufacturers put forward higher requirements for the quality of SG295 steel plate. Welding gas cylinder is made by stamping and welding, so SG295 steel plate must have good stamping and welding performance.
The special use of welding gas cylinder determines that SG295 steel plate must have higher strength and lower embrittlement temperature. Therefore, the analysis and study of the factors affecting the performance of SG295 steel plate have important practical significance for stabilizing the mechanical properties of gas cylinder steel and improving its quality.
The key to stabilize the quality of SG295 steel plate is:
1. select the chemical composition of the mechanical properties of SG295 steel plate to ensure the stable properties of SG295 steel plate.
2. sulfur and inclusion in steel are the elements that directly affect the mechanical properties of SG295 steel plate. As the content of sulfur and inclusion increases, the plasticity of SG295 steel plate decreases obviously. Therefore, the intensified smelting desulfurization process was adopted to control the temperature and alkalinity in the furnace of SG295 steel plate in the middle and late stage, and the oxidation property of the terminal point was controlled by high tension and filling blowing.
