The thinning rate of stainless steel stretching parts is not a fixed value, it depends on various factors, including the original thickness of the plate, the amount of stretching during the processing, material type, processing technology, etc. Therefore, it is not possible to provide an exact value for the thinning rate.
The thinning rate is the ratio of the change in sheet thickness to the change in elongation during the stretching process of a sheet, usually expressed as a percentage. In the cold drawing, cold rolling, stamping and other processing processes of stainless steel sheets, thinning rate is an important consideration factor, which directly affects the machinability and final performance of stainless steel sheets.
In order to obtain accurate thinning rate values, specific experiments and measurements are usually required. This involves precise measurement of the original thickness, final thickness, and stretching amount of the board, and calculation based on the formula for thinning rate.
Therefore, if you need to know the thinning rate of specific stainless steel stretching parts, it is recommended that you consult the relevant manufacturer or conduct actual measurements and calculations.
