The main factors of affecting non-metallic inclusions in SS490 molten steel are: the process control of smelting process and the quality of original paving mate
Non-metallic inclusions exist in SS490 steel as an independent phase, which destroys the continuity of the steel matrix, increases the inhomogeneity of the SS49
In the SS490 steel welding process, the original austenite grains around the weld grow abnormally by the thermal cycle, leading to poor weld quality. However, i
