Low alloy steel Q345E angle steel bar can be composed of various stress-bearing components according to the different needs of the structure, and can also be used as a connecting piece between the components. A514 grade B alloy steel plate, Q345E angle steel is widely used in various building structures and engineering structures, such as house beams, bridges, power transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.
The mechanical properties of 30CrMo steel are as follows: tensile strength 930 MPa, yield strength 785 MPa, elongation after fracture 12%, impact absorption energy 63 J. A514 grade B alloy steel plate, 30CrMo steel has high strength and toughness. When the temperature is lower than 500℃, 30CrMo steel has good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance. 30CrMo steel is generally used in quenched and tempered condition.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the A514 grade B alloy steel plate metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between A514 grade B alloy steel plate strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled A514 grade B alloy steel plate plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive A514 grade B alloy steel plate industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.
