Products Description
The chemical composition of DH40 ship plate mainly includes iron, carbon, manganese, silicon, phosphorus, sulfur and other elements. Among them, iron and carbon are the basic elements of steel, manganese and silicon can improve the strength and hardness of steel, phosphorus and sulfur affect the mechanical properties and processing properties of steel. The internal structure and mechanical properties of DH40 ship plate can be improved by proper heat treatment process.
Application of DH40 ship plate
As a kind of high strength and low alloy structural steel, DH40 ship plate is widely used in the fields of ships and Marine engineering structures. For example, in shipbuilding, DH40 ship plates can be used to manufacture key parts such as hull structure, deck and bulkhead; In the Marine engineering structure, DH40 ship plate can be used to manufacture platform, jacket and other structural parts. Its excellent mechanical properties, welding properties and good corrosion resistance can improve the safety and service life of ships and Marine engineering structures.
DH40 Features
High strength: DH40 ship plate has high tensile strength and yield point, and can withstand large loads and impacts.
Low alloy: DH40 ship plate is added with appropriate amounts of alloy elements, such as Mn, Si, Cr, etc., to improve its comprehensive mechanical properties and corrosion resistance.
Good welding performance: DH40 ship plate has good welding performance and is easy to weld.
Corrosion resistance: Through the addition of alloy elements and surface coating treatment, DH40 ship plates have certain corrosion resistance.
