Die steel is a type of steel used to manufacture cold stamping dies, hot forging dies, die- casting dies and other molds. Molds are the main processing tools for manufacturing parts in industrial sectors such as mechanical manufacturing, radio instruments, motors, and electrical appliances. The quality of molds directly affects the quality of pressure processing technology, the precision and output of products, as well as production costs. The quality and service life of molds, apart from relying on reasonable structural design and processing accuracy, are mainly influenced by mold materials and heat treatment.

Due to the harsh working environment of ships, the hull shells are subject to chemical corrosion and electrochemical corrosion by seawater, as well as corrosion by Marine organisms and microorganisms. The hull is subjected to considerable wind and wave impacts and alternating loads. The shape of ships makes their processing methods complex and other factors, so strict requirements are imposed on the steel used for the hull structure. First of all, good toughness is the most crucial requirement. In addition, it is necessary to have high strength, good corrosion resistance, welding performance, processing and forming performance, as well as surface quality.

Characterlstics:
It features high strength, light self- weight, good overall rigidity and strong resistance to deformation. Therefore, it is particularly suitable for the construction of large-span and super-high and super-heavy buildings. The material has good homogeneity and isotropy, and is an ideal elastomer, which best conforms to the basic assumptions of general engineering mechanics. The material has good plasticity and toughness, can undergo significant deformation, and can well withstand dynamic loads. The construction period is short. It has a high degree of industrialization and can carry out specialized production with a high degree of mechanization.
Steel structure components are convenient to be manufactured in factories and assembled on construction sites. The finished products of steel structure components manufactured mechanically in factories feature high precision, high production efficiency, fast assembly speed on construction sites and short construction periods. Steel structure is the most industrialized type of structure.
