Notes:
• The table contains processed, condensed data from EN 485-2.
• Bend radius values are indicative (rmin ≈ k·t).
• HBW: Brinell hardness, carbide-ball test.
• Ahol A50 is not given, the general elongation value “A” is stated in the standard.
The values and data below are indicative – they help to give a general picture of the material.
