The toughness of steel such as SA514 Grade A high-strength structural steel is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.
The company specializes in steel plate cutting, steel plate processing and wide thick plate, hot rolling coil. The company possesses advanced CNC steel plate cutting processing equipment, first-class technical personnel, supporting marketing and after-sales service system. Steel plate cutting parts are mainly used in mechanical manufacturing, shipbuilding, steel structure and mold processing industries, and we can provide SA514 Grade A high-strength structural steel, finished products and semi-finished products processing according to the needs of users.
Structural steel for construction is used to build boilers, ships, bridges, workshops and other building materials. This kind of steel usually needs welding construction, so it is generally low carbon steel with carbon content less than 0.25%, which is mostly used in hot rolling or normalizing state. SA514 Grade A high-strength structural steel, Structural steel for machinery is used for manufacturing machines or mechanical parts. This kind of steel is often used after carburizing or quenching and tempering. The steel used for carburizing is low carbon steel with carbon content of 0.1% ~ 0.3%. Steel used for quenching and tempering refers to medium carbon steel with carbon content of 0.3% ~ 0.6%.
In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel SA514 Grade A high-strength structural steel surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.
