The raw materials of distribution box are mostly cold-rolled steel plate.

 

Cold rolled steel is generally divided into ordinary grade (C < 0.12%), low carbon grade (C < 0.10%) and ultra-low carbon grade (C < 0.08%). The lower the carbon content, the better the cold plasticity. Cold rolling is cold working, including cold drawing and cold drawing, which can remove rust and straighten. The important thing is to change the properties of steel through cold drawing strengthening and steel aging! At present, a considerable number of production enterprises use ordinary grade cold rolled steel, so compared with low carbon grade and ultra-low carbon grade, ordinary grade can reduce the cost in terms of cost, but its quality is not as good as both. Therefore, when choosing, it is better to choose relatively low carbon grade cold rolled steel.
