1)U rimming. R killed (including balanced steel), RR special killed
2)It is permissible to axcased the maximum value indicated, provided a phosphorous content per 0.001% N of 0.005% P below the maximum value indicated is maintained. THe nitrogen content may not, however, exceed a value of 0.0012%N in the ladle analysis and 0.0014%N in the sample analysis.
3)The content may not exceed 0.55%Si and 1.60% Mn in the ladle analysis or 0.60%Si and 1.70% Mn in the sample analysis.
4)Maximum 0.22% C for steels KSt 52-3 and RoSt 52-3 according to Table 3
5)In the case of steels suitable for bright drawing according to Table 3 the following gulde vatues for the carbon content can be assumed:
0.30% C for Z St 50-2, 0.40% C for ZSt 60-2, 0.50% C for Z St 70-2
6Maximum 0.24% C for steels KSt 52-3 and RoSt 52-3 according to Table3

1) The values of the tensile test and the bending test apply to longitudinal specimens apart from flat products ≥ 600mm width from which transverse specimens are to be taken.
2) U hot formed, untreated, N normalized.
3) For notched-bar impact specimens with a width of less than 10mm the specifications
4) The test result is the average value from three tests. Only one individual value may be lower than the minimum average value of 23 or 27J, and then only by a maximum of 30%.
5) This value applies only to thicknesses up to 25mm.
