Applicability and limitations
DIN EN10270-3:2012-01 adopts EN10270-3:2011; this record uses composition from the verified original text of that EN edition.. EN 10270-3:2011 Table 1 heat analysis, mass fraction wt%; The source is an official public SIST excerpt of 11 pages; all 6 rows of Table 1 and notes a–e are included in full.. The scope is stainless spring steel wire with a circular cross-section diameter ≤10mm, usually delivered in the cold-drawn condition.; Mechanical requirements must be agreed upon for 10–15mm and other steel types not listed separately in Table 1; cold-heading product applicability shall not be automatically confirmed based on this. Table 1 Note a allows other compositions to be agreed upon; the ranges listed in the table shall not be altered without such agreement.; Clause 4.4.2: Apply product-analysis tolerances separately under EN10088-3; for the same element in the same heat, deviations must not occur both above the upper limit and below the lower limit.. Note c allows the use of 1.4436 to improve corrosion resistance, subject to the provisions of this standard for 1.4401.; The chemical composition of 1.4436 is not listed separately in this table and shall not be duplicated as the same composition. Note d allows the Ni upper limit to be increased to 8.30% only when improving the cold forming performance of X7CrNiAl17-7, which is listed as a separate condition.; Unlisted elements are not entered as zero. Chemical clauses and footnotes have been verified; it is not declared that all mechanical properties, dimensional tolerances, tests, and annex contents have been verified..
