45 Steel Marine Shaft
The marine shaft consists of the propeller shaft, intermediate shaft, thrust shaft, coupling, intermediate shaft bearing, stern shaft bearing and so on. It serves as the connection between the vessel's engine and propeller.
This steel marine shaft is made from 45 steel and is also called C45E +QT in German designation and 1045 in American designation. After quenching, the 45 steel has a hardness greater than others. The 45 steel is a high-quality carbon structural steel. Its hardness is not high, which is easy to cut. Compared with ordinary A3 steel, it has higher strength and deformation resistance.
Overview
The 45 steel is a high-quality carbon structural steel commonly used in the manufacturing of marine shafts due to its excellent mechanical properties and cost-effectiveness. This medium-carbon steel contains about 0.42% to 0.50% carbon, which provides a good balance of strength, toughness, and wear resistance. This marine shaft can be heat treated to further enhance its properties. Processes such as quenching and tempering can increase its hardness and strength, making it even more suitable for heavy-duty marine applications.
