How to distinguish Q235 steel and Q345 steel?

How to distinguish Q235 steel and Q345 steel?

The appearance of Q235 steel and Q345 steel are almost the same. The color difference has nothing to do with the material of the steel, but is caused by the different cooling method after the steel is rolled. Under normal circumstances, the surface of the
Advantages and disadvantages of hot rolled steel

Advantages and disadvantages of hot rolled steel

By definition, steel ingots or billets are difficult to deform and process at room temperature. They are generally heated to 1100°C to 1250°C for rolling. This rolling process is called hot rolling. Most steels are rolled by hot rolling. T
