Please see Table 1: Chemical composition (ladle analysis, %) as per SANS 50025 / EN 10025 of the first page of the related link.
the equivalent for c45 is en-8 and en-19 is c55 Need the Chemical composition and mechanical properties of C45 and EN-8 also to C55 and EN-19
en 45 is a silicon mangenese spring steel, supplied in the as rolled contition. This steel is suitable for oil hardening and tempering.
C%-0.58-0.65 Mn%- 0.80-1 Si%- 1.70-2.10 P%- 0.035
The chemical composition is: - C: max. 0,2 % - Mn: 0,5-1,o - Si: max. 0,35 - S: 0,04 - P: 0,04 - Cr: 0,75-1,25 - Ni: 1,0-1,5 - Mo: 0,08-0,15
EN series is the outcome of British Standard(BS970) steels developed during world war time. Slowly this series is replaced by DINEN series now. Almost all stells are conered in EN series.
X3CrNiMo13-4
Please see BS 970 for detailed description. The chemical composition is: - C: max. 0,2 % - Mn: 0,5-1,o - Si: max. 0,35 - S: 0,04 - P: 0,04 - Cr: 0,75-1,25 - Ni: 1,0-1,5 - Mo: 0,08-0,15
