Composition based on ISO 4954:2018; the product edition is unspecified, so confirm the edition applicable to the contract.

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.

Heat-analysis mass fractions wt%; Product-analysis tolerances require separate verification under Table 2. ; The agreed sulfur condition in Table 1, note b applies only to grades marked b; default, machining and welding ranges are retained separately. ; This standard covers steels and nickel alloys for high- and low-temperature fasteners; cold-heading suitability is not established for every grade or delivery condition. ; Unlisted elements must not be intentionally added without purchaser consent, except additions needed to finish steelmaking; Unspecified values are not treated as zero.

Original text NF EN10269 cover novembre1999, Table 1 heat analysis mass fraction %. ; Table 1, Note 2: Sulfur .015–.030% is a recommended range for improved machinability; it does not replace the default maximum.; This note does not apply to 42CrMo4 as it is not marked. ; Elements not listed shall not be intentionally added without the purchaser's consent (except additions needed to finish steelmaking); blanks are not zero. ; Standards for high- and low-temperature fastener steels and nickel alloys; Composition alone does not prove that cold-heading wire is available or suitable for forming. ; Product-analysis deviations require separate verification under Table 2; they do not expand the default heat-analysis range.; Sulfur limits of the 2013 version do not apply.

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.

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.

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.

The S 0.015–0.030% machinability recommendations, 0.008–0.020% weldability recommendation and S≤0.015% polishability recommendation in note b concern specific properties and do not directly replace this row’s sulfur limits.
