1 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.
Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

Applicability and limitations
The original webpage states DIN EN 10263-5-2018; The composition in this record was actually verified against DIN EN 10263-5-2002; the edition is now identified as 2002 according to the original evidence; See the separate complete-table record for edition 2018. ; Source actually used: DIN EN10263-5:2002-02, the German-language adoption of EN10263-5:2001; PDF8, Table 2 and notes a–e. ; Default heat analysis in wt%.; Apply product-analysis tolerances in Table 3 separately; do not add them to the default heat-analysis range. ; Unlisted elements must not be intentionally added without purchaser consent, except additions needed to finish steelmaking; Residual elements must not impair the properties or intended use. ; The older table does not use the 2017 edition’s separate sulfur conditions; do not copy machining/welding/polishing options from the newer edition.. ; For Ti-stabilized grades, check 5×C≤Ti≤0.70% against measured C.; Does not apply to grades for which Ti is not specified. ; Standard range for cold-heading and cold-extrusion; actual supply, dimensions, delivery condition, and performance still require confirmation..
