Q345B Angle steel

Q345B angle steel is a type of low-alloy high-strength steel that is commonly used in construction and engineering structures such as buildings, bridges, and transmission towers. The chemical composition of Q345B angle steel typically includes carbon, manganese, silicon, sulfur, phosphorus, and sometimes other elements such as chromium and nickel. The specific composition can vary depending on the manufacturing process and intended application. Q345B angle steel typically has a yield strength of 345 MPa and tensile strength of 470-630 MPa. It is known for its good welding and cold forming properties.
