Advantages of cold rolled A ST52 steel

Advantages of cold rolled A ST52 steel

A ST52 steel products have precise dimensions and uniform thickness, and can obtain coils that fully meet the requirements of high-precision tolerances. Good performance, many varieties and wide uses. With the heat treatment process, it can produce A ST52

Cold rolled A ST52 steel is more popular than hot rolled A ST52 steel

Cold rolled A ST52 steel is more popular than hot rolled A ST52 steel

As we all know, due to the process characteristics of "three highs and one low", hot rolling technology will cause certain defects in rolled steel sheets. The main disadvantage is that the iron oxide scale produced during high temperature rolling (800 ℃
