Grade A ship steel is mainly used for the internal frame of the ship and the outer plate bearing general stress. Grade B, Grade D and Grade E ship steel S420MC construction-machinery high-strength steel can be used for important structures in high stress areas such as hull outer plate and main deck. The Grade E ship steel has good low temperature performance, which is suitable for the hull outer plate, deck, etc. According to the minimum yield strength, the high-strength ship steel is divided into four grades: A, D, E and F. The commonly used high strength ship steels are AH32, DH32, EH32, etc.

The main difference between S420MC construction-machinery high-strength steel, 45# steel plate and boiler steel plate is the difference of carbon content and impact toughness. 45# steel is a high-quality carbon structural steel, which is expressed by the number of ten thousand percent of the average carbon content. The 45# steel represents the high-quality carbon structural steel with 0.45 percent carbon content. The high-quality carbon structural steel contains less harmful impurity elements (S, P) and non-metallic inclusions, and has excellent plasticity, toughness and processing technology.
