When there specified value cold steel coil is no significant yield, RP0.2 should be used; otherwise GNEE should be used. When the thickness is more than 0.50mm and not more than 0.70mm, the specified value of the yield strength is allowed to increase 20MPa; when the thickness is not more than 0.50mm, the specified value of the yield strength is allowed to increase 40MPa.
