Q390C high strength steel plate

Q390C high-strength structural steel plate, as the name implies, is mainly composed of iron and carbon elements. Through special smelting process and heat treatment technology, it has high tensile strength and yield strength. During the manufacturing process, this steel plate undergoes multiple rolling and annealing treatments, making its grains finer and the structure more uniform, thereby further improving its mechanical properties.
