EN 10088-1:2005 Table 4 and continuation: ladle analysis (wt%); the official SIST adoption preview PDF, pages 11/12, covers all 50 grades and notes. Note a: unlisted elements are not intentionally added without purchaser consent, except as needed to complete steelmaking; a blank is not zero. Note b: for grades marked b only, S is selected separately for long products and by property requirement. Note d: the increased Ni maximum for special reasons applies only to listed grades, not all grades. Note c: Cu up to 1.0% for cold heading/extrusion; this condition path is provided here only for grades with blank Cu in the original table. Existing Cu alloy ranges retain their original values; the exception has not automatically rewritten them. The linked Ti≥5C/Nb≥10C and Ti≥8(C+N) conditions are retained; an unlisted N maximum is not zero. Note e: the source warns of skin-contact regulatory issues for high-sulfur free-machining steel; this is retained as a historical warning only and is not a claim of current compliance based on the 2005 text. Listed chemistry and the cold-heading Cu exception alone do not establish overall cold-heading performance or company supply; mechanical and product standards must be checked separately, and national adoption does not mean automatic equivalence.
