Rolling direction and transverse direction

WebThe orientation of the bend relative to the rolling direction of the strip is important. Strip alloys typically are more formable when bends are made in the longitudinal (good way) direction than bends made in the transverse (bad way) direction. (Figure 3) Therefore, formability is specified in both the longitudinal and transverse direction. Webthe transverse direction than the longitudinal direction, and that the yield strength is 3% higher. This creates a situation where the contact will experience 20% more stress, but it will ... When this happens, it is easy to lose track of the rolling direction of the strip sample. It is entirely possible that prototypes will be made with one ...
