The process of Production and Cutting for A573 Gr70 steel

In order to produce high-quality A573 Gr70 steel, every step has strict requirements. Let's briefly understand the production process of A573 Gr70 steel and focus on its cutting method.

·Production process of A573 Gr70 steel :
Fore-melt → LF refining → VD treatment → continuous casting (mold casting) → cleaning, heating → rolling → stacking → inspect the surface → batch → flaw detection → heat treatment → cutting sampling → inspect the performance → warehousing.

·Cutting process of A573 Gr70 steel:
After all performance indicators of A573Gr70 steel plate meet the requirements of factory inspection, A573Gr70 steel plate can be cut and processed according to the cutting process. Generally, CNC plasma cutting or CNC laser cutting are preferred when the thickness of A573 Gr70 steel plate within 20mm. If the thickness of A573 Gr70 steel plate over 30mm, CNC flame cutting is usually chosen to control the accuracy and time of cutting.
