High-strength steel plate

High Strength Steel Plate is a material used to make several products from plates to sheets. The properties inherent by these plates depend upon the elements added to them. High Strength Steel Plate is one such type of plate that has improved strength, formability, and weldability.

High-strength steel plate advantage

Generally, the tensile strength of high strength steel plate is about 400-450MPa. Hot forming steel is formed by heating. After a series of treatments, the tensile strength can be increased to 1300-1600 MPa, which is 3-4 times that of ordinary steel.High strength steel plate (high strength plate) refers to the brand Q460 steel, high strength, especially in the normalizing or normalizing and tempering state has higher comprehensive mechanical properties.

High-strength steel plate application

 Mainly used in large ships, Bridges, power plant equipment, medium and high pressure boilers, high pressure vessels, rolling stock, lifting machinery, mining machinery and other large welding structural parts.
