1) The values of the yield strength are those of the 0.2% yield strength for products with no definite yield point,
and the lower yield strength ReL for the other products 2) For a thickness t ≤ 0.7 mm the minimum elongation after fracture is decreased by 2%. 3) This value only applies to skin-passed products
4) For a thickness t > 1.5 mm the r90 value is reduced by 0.2. |
