What is the Q460C alloy?

Q460C alloy: Q460C material is a low alloy high strength steel. Q represents the capitalization of the first letter of the Chinese alphabet of the "yield" character of the yield strength of steel; 460 represents 460 MPa, mega is the 6th power of 10, Pa is the unit of pressure Pascal; Q460 is the strength of steel Plastic deformation occurs only when 460 MPa is reached, that is, when the external force is released, the steel can only maintain the shape of the force and cannot return to its original shape. This strength is greater than that of ordinary steel. C—The quality level is C level (the level is divided into C, D, E).
