Q345C/Q345D/Q345E steel processing technology and material composition performance

1. Specification for implementation of Q345C/Q345D/Q345E steel plates: GB/T 3274-2017.

2. The material of Q345C/Q345D/Q345E steel plate is: high-quality low-alloy structural steel plate

3. The thickness of Q345C/Q345D/Q345E steel plate is 8mm-100mm.

4. Heat treatment of Q345C/Q345D/Q345E steel plate: in the state of hot rolling or heat treatment (annealing, normalizing or high temperature tempering).

5. Q345C/Q345D/Q345E steel plate specification, shape, weight and allowable error.
The specification, shape, weight and tolerance of Q345C/Q345D/Q345E steel plates conform to the regulations of GB/T709.

6. Q345C/Q345D/Q345E steel plate cutting and slitting.
Q345C/Q345D/Q345E steel can be normalized and tempered by hot rolling.

Q345C/Q345D/Q345E steel plate belongs to low alloy steel. Low alloy steels are used for general engineering structures or for a variety of other purposes. The minimum yield strength of low alloy steel is higher than 275MPa, up to 1035MPa.
Low-alloy steel is based on carbon steel by adding a small amount of alloying elements to make it not only have high strength but also have good comprehensive properties such as toughness, welding performance, formability, and corrosion resistance in the hot-rolled or heat-treated state. characteristics.
