1)Approximate values.

Note: it is possible to specify the hardness values or the tensile strength values, but not both. If neither of the two values is specified, the tensile strength value is calculated.
The hardness/tensile strength specification must fall within a range of 150 N/mm² or 50 HV, unless stated otherwise in the commercial agreement.

EN 10132-2:2000

The requirements regarding roughness can be agreed when requesting the quote or placing the order.
Cold-rolled strips should have a bright surface finish, as obtained during rolling or annealing in a controlled atmosphere.
