No, ductility is measured as at least 14% elongation and at least 30% reduction in area. I have a chart listing the following fasteners as ductile by this definition:
ASTM A307 A or B
ASTM A 354 BC or BD
ASTM A 449 Type 1
ASTM A 687
ASTM F 1554 GR 36, 55 or 105

Subject: Brittle and Ductile steel elements
Hello All
In regard to anchors embedded in concrete ACI 318 App D regarding Brittle and Ductile steel elements
Is it correct to assume if the Fu of the bolt is 65ksi or less then it is Ductile and over 65ksi is Brittle ??
