    a The definition of deoxidation method is as follows:

    FN = Boiling steel is not allowed

    FF = fully-killed steel containing nitrogen-binding elements in an amount sufficient to bind possible nitrogen

    (E.g. 0.020% minimum total aluminum or 0.015% soluble aluminum)

    b It is allowed to exceed the specified value, as long as the N content increases by 0.001%, the maximum content of P decreases by 0.005% at the same time. The N content in the smelting analysis should not exceed 0.012%.

    c If the chemical composition shows a minimum total aluminum content of 0.020% and a minimum Al / N ratio of 2: 1, or if other sufficient nitrogen-binding elements are present, the above maximum nitrogen content limits do not apply. Nitrogen binding elements shall be noted in the inspection documents.

    a Longitudinal sample value. The standard value of the transverse specimen is 2% lower than this value.b For thicknesses <3mm, see 9.2.2.c Only when option 1.3 is applied, confirmation of impact performance is required.d See 6.6.2 for the impact properties of small-sized specimens.e This value is equivalent to 27J at -30 ° C (see EN 1993-1-1).
