Introduction to Steel Products / Ultra-Thick Carbon Steel Plates (Including Technical Data)
It is possible to manufacture ultra-thick carbon steel. This time, we will introduce the manufacturing data for ultra-thick steel plates of ASME SA516 Gr.70 with a thickness of 200mm.
One of our strengths is our ability to handle extremely thick steel plates exceeding 200mm, even from a single piece. Generally, we ensure a rolling ratio of 3 or more for steel plates, but this time we have compiled data for the case of a rolling ratio of 2, specifically for a steel plate of 200mm thickness made from ASME SA516 Gr.70.
