Elements not listed in this table shall not be intentionally added to the steel without the approval of the purchase except for finishing the cast. All appropriate measures shall be taken to
prevent the addition from scrap or other materials used in steelmaking of these elements which may have adversely affect the mechanical properties and usability.

The thickness ranges given in this column apply for the as heat treated thickness of forgings with the ruling section.
This is characterized by rectangular shape, a width to thickness ratio of ≥ 2 and a length to thickness ratio of ≥ 4.
For forgings with other sections the equivalent thickness shall be determined according to EN 10222–1:2017,
Annex A or be agreed at the time of enquiry and order.
b
Until the yield point criteria are harmonized in the various national codes, determination of R may be replaced

by determination of Rp0,2. In this case Rp0,2 values are 10 MPa lower for ReH values up to 355 MPa and 15 MPa lower
for R values greater than 355 MPa.

l = longitudinal to main forging directions; t = tangential; tr = transverse to main forging directions.

Maximum room temperature for the impact test is 20 °C. By option, impact testing may be carried out at 0 °C, with
the condition to fulfil the impact values as stated in this table.
