Q345 S235 Steel Angle

Q345 Steel is a type of low-alloy steel, that is used in the manufacturing of bridges, buildings, and other structures. It has a yield strength of 345 MPa and tensile strength of 470-660 MPa. S235 grade steel is a readily weldable low carbon manganese steel with good impact resistance (including in sub-zero temperatures). This material is commonly supplied in the untreated or normalised condition and is available in several variations (denoted by additional letters and/or digits), which offer slight modifications of chemical composition and mechanical properties.

Products Description

Comprehensive performance of Q345

Q345 has good comprehensive mechanical properties, low temperature performance, good plasticity and weldability. It is used as the structure, mechanical parts, building structure, general metal structural parts, heat, etc. bearing dynamic load for medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations, bridges, etc Used in rolling or normalizing state, it can be used for various structures in cold area below – 40 ℃.

Grade classification of Q345

Q345 can be divided into Q345A, Q345B, Q345C, Q345D and Q345E by grade. What they represent is that the impact temperature is different. Q345A, no impact; Q345B, impact at 20 ° normal temperature; Q345C, 0 degree impact; Q345D, is – 20 degree impact; Q345E, is – 40 degree impact. At different impact temperature, the impact value is different.
