The invention discloses a central beam of a hopper car and the hopper car with the same. The central beam of the hopper car comprises a central beam body and a guide part, wherein the central beam body is made of stainless steel, a through hole is formed in the central beam body in the extending direction of the central beam body, and the guide part is arranged on the upper surface of the central beam body and fixed to the central beam body. The central beam body is made of stainless steel, so that when the central beam body makes contact with coal, the central beam body is not corroded. A stainless steel wrapping plate does not need to be arranged on the outer surface of the central beam body, and therefore the self weight of the central beam is reduced, additional welding stress caused in multi-layer welding process is reduced, the structural strength and rigidity of the whole car are increased, and the technical problems that as a central beam is wrapped with a stainless steel wrapping plate in the prior art, the weight of the central beam is increased, and a connecting welding joint is added, so that the structural strength of the hopper car is affected are resolved.
