Results of the Study of Microwaviness of Galvanized Rolled Products after Stamping
摘要
Abstract
The results of the study of microwaviness of metal after stamping at the customer have been presented. To study the effect of stamping on the return of microwaviness and to ensure the requirement after stamping Wsa < 0.35 μm, six batches are selected, some of which had a microwaviness after galvanizing at a level of less than 0.35, one of the batches had a microwaviness exceeding the requirement. The results of stamping showed that the value of the return of microwaviness is on average 0.1 μm, therefore, to ensure the requirement for microwaviness after stamping, the certification standard for galvanized rolled products should be stiffened.
