A steel piston () for an internal combustion engine comprises a ring zone (), a shaft (), openings () between the ring zone () and shaft () which extend from the piston outer side to the piston inner side, and, between two openings (), a rib () which is substantially central with respect to a length of a piston pin to be received, wherein, when viewed in the circumferential direction, the rib () has a decreasing thickness from the middle thereof, as measured in the radial direction. In a method for producing a steel piston for an internal combustion engine comprising a ring zone and a shaft, openings are formed between the ring groove region and the shaft which extend from the piston outer side to the piston inner side, and at least one rib is formed between the openings which is substantially central with respect to a length of a piston pin to be received, wherein, when viewed in the circumferential direction, the rib () has a decreasing thickness from the middle thereof, as measured in the radial direction.
