Note

1. The solution treatment may be omitted if the conditions for hot working and subsequent cooling are such that the requirements for the mechanical properties of the product and the resistance to intergranular corrosion as defined in EN ISO 3651-2 are obtained.
2. C= Cold rolled strip; H= hot rolled strip; P= hot rolled plate.
3. If, in the case of strip in rolling widths<300mm, longitudinal test pieces are taken, the minimum values are reduced as follow:
   1. proof strength: minus 15N/mm²
   2. elongation for constant gauge length: minus 5%
   3. elongation for proportional gauge length: minus 2%
4. For continuously hot rolled products, 20N/mm² higher minimum values of R_p0.2 and 10N/mm²higher minimum values of R_p1.0 may be agreed at the time of enquiry and order.
5. The values apply for test pieces with a gauge length of 80mm and a width of 20mm. Test pieces with a gauge length of 50mm and a width of 12.5mm can also be used.
6. The values apply for test pieces with a gauge length of 5.65 S_o^0.5

3. The Brinell or Vickers or Rockwell hardness is normally determined for product forms C and H in heat-treatment condition A. The tensile test shall be carried out in referee testing.
4. The values apply for test pieces with a gauge length of 80mm and a width of 20mm. Test pieces with a gauge length of 50mm and a width of 12.5mm can also be used.
5. The values apply for test pieces with a gauge length of 5.65 S_o^0.5
6. Plates may also be delivered in the annealed condition; in such cases the mechanical properties are to be agreed at the time of enquiry and order.

Note

1. C= Cold rolled strip; H= hot rolled strip; P= hot rolled plate.
2. If, in the case of strip in rolling widths < 300mm, longitudinal test pieces are taken, the minimum proof strength values are reduced by 15N/mm²
3. For continuously hot rolled products, 20N/mm² higher minimum values of R_p0.2 may be agreed at the time of enquiry and order.
4. The values apply for test pieces with a gauge length of 80mm and a width of 20mm. Test pieces with a gauge length of 50mm and a width of 12.5mm can also be used.
5. The values apply for test pieces with a gauge length of 5.65 S_o^0.5
