The thickness of stainless steel plate
1. During the rolling process of the steel mill machinery, the rollers are heated and slightly deformed, which leads to deviations in the thickness of the rolled plates. Generally, the thickness of the middle and the sides are thin. When measuring the thickness of the board, the state stipulates that the middle part of the board head should be measured.
2. The reason for the tolerance is that according to the market and customer needs, it is generally divided into large tolerance and small tolerance: for example
