BS EN 10263-5:2017; Heat analysis, mass percent; Values without a stated range are maxima; Notes below the table are retained. No edition is stated on the website; Displayed under this source edition; contract applicability is not established

ISO 4954:2018; heat analysis, mass fraction %; values without a stated range are upper limits; see the source page for complete table footnotes. The website does not specify the edition; the source edition is shown here and does not establish contractual applicability.

ISO 4954:2018 Table D.2 gives cast analysis; single values are maxima and dashes are not zero.

Product-analysis deviations are listed separately under Tables 2/3, not used directly to relax cast-composition limits.

Elements not listed must not be intentionally added without the purchaser's consent, except for finishing the heat.

Heat-analysis mass fractions wt%; Product-analysis tolerances follow Table 4 separately. ; The sulfur conditions for machining, welding and polishing in Table 3, note b are retained separately; different requirements are not imposed simultaneously. ; Ti-stabilized grades require 5×C≤Ti≤0.70%, checked jointly with measured C/Ti. ; This standard covers stainless steel for cold heading and cold extrusion; delivery condition, dimensions, surface and mechanical properties still require independent confirmation. ; Unlisted elements must not be intentionally added without purchaser consent, except additions needed to finish steelmaking; unspecified contents are not treated as zero.

Actual source: DIN EN 10263-5:2002-02; German adoption of EN 10263-5:2001, PDF p. 8 Table 2 and Notes a–e.

Default is ladle analysis, mass fraction wt%; product-analysis deviations are separately governed by Table 3 and are not added to default ladle ranges.

Unlisted elements must not be intentionally added without purchaser approval (except as necessary during steelmaking); residual elements must not impair performance or use.

This older edition does not use the 2017 edition’s conditional sulfur provisions; do not copy newer machining/welding/polishing options.

For Ti-stabilized grades, verify 5×C≤Ti≤0.70% using measured C; do not apply this condition to grades without Ti.

The standard covers cold heading/cold extrusion; actual supply, dimensions, delivery condition and properties still require confirmation.

Official English original text of DIN EN10270-3:2001-08; Table 1 heat analysis, mass fractions wt%. ; The scope is for commonly cold-drawn round cross-section stainless spring steel wire with a diameter ≤10mm; 10–15mm shall follow mechanical requirements agreed by both parties; this does not automatically confirm the supply of cold-heading products. ; Product analysis tolerances in Clause 5.4.2 shall be governed separately by EN10088-3 and shall not directly expand the default heat analysis composition. ; Table 1 Note a allows other compositions to be agreed upon by both parties; Do not enter an agreed composition where no contractual agreement exists.. ; Note c allows the use of 1.4436 as a substitute for 1.4401 to improve corrosion resistance, but since the independent chemical composition of 1.4436 is not listed in this table, it shall not be duplicated as the same composition based on this. ; The Ni increase condition in Table 1 Note d is selected separately; blank Mo/N etc. shall not be filled as zero.

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.
