1. When there is no obvious yield, use Rp0.2; otherwise use Rel.
|
|
2. When the nominal thickness of the product is greater than 0.5mm but not greater than 0.7mm, the elongation is allowed to decrease by 2%; when the nominal thickness of the product is not greater than 0.5mm, the elongation is allowed to decrease by 4%.
