Diesel engine exhaust valves for ships combine the different characteristics of wear resistance on the outer side and high temperature resistance on the inner side, while using the same high corrosion resistance material. This was made possible by the excellent cooperation between the large forging machine and the radial forging machine of which Daido Steel is proud.
Due to our original technology and reliability, our domestic share is 100%. We also have approximately a 60% share of the world market. Daido Steel's ship products that excel in corrosion resistance and heat resistance sail the oceans of the world.
