What are the properties of Q345D low alloy angle steel?

Q345D low alloy angle steel has good processing properties like stampability, weldability, cold bending and heat treatment. For the detailed info, please go through the following message.

1. Stampability

Stampability refers to the performance that the metal undergoes stamping deformation without defects such as cracks. Many metal products are manufactured through stamping processes, such as automobile shells, enamel product blanks, and daily necessities such as pots, basins, bowls, and pots. In order to ensure the quality of the products and the smooth progress of the process, the metal plates and belts used for stamping must have qualified stamping performance.

2. Weldability

Weldability refers to the performance of the welded joints where the metal is obtained by the common welding methods under the specific structure and process conditions with the expected quality requirements. Weldability is generally judged based on the crack sensitivity generated during welding and the changes in the mechanical properties of the weld zone.

3. Cold bending

The ability of metal materials to withstand bending without breaking at room temperature is called cold bending. The greater the degree of bending that can be tolerated before a crack occurs, the better the material's cold bending performance.

4. Heat treatment

Heat treatment refers to a process operation in which the metal or alloy is in the solid range, through certain heating, heat preservation and cooling methods to change the internal structure of the metal or alloy to obtain the desired performance. Heat treatment process refers to the ability of metal to change its structure and properties after heat treatment, including hardenability, hardenability, temper brittleness and so on.
