Official German DIN 2003-04 adopts EN10132-4:2000+AC:2002; PDF6, Table 1 gives heat-analysis mass fractions wt%. ; Cold-rolled narrow strip for heat-treatment applications; Covers spring steels and other special applications; it does not establish a basis for supply as cold-heading wire rod. ; Product-analysis tolerances in Table 2 are listed separately and are not mixed with the default heat-analysis range in Table 1; Within the same heat, ±tolerances must not be exceeded in both the lower and upper directions. ; Elements not listed in the table must not be intentionally added without purchaser consent, except to finish steelmaking; unspecified contents are not treated as zero. ; AC:2002 corrects the annealed/lightly skin-passed properties in Table 3; Only the complete Table 1 chemical composition was checked in this batch; mechanical properties require separate verification.

The original target EN10132:2021 has not been verified; Currently uses only the historical same-grade reference in DIN EN 10132-4-2000(+AC:2002); this does not establish the requirements or scope of edition 2021 or conformity of supplied material.

The chemical composition currently shown is transcribed from the original DIN EN 10132-4-2000(+AC:2002); The original record cites EN 10132-4-2002; that original edition remains unavailable, and differences between editions have not been confirmed.

A match in the materials database does not establish suitability for cold heading or guarantee finished-product strength. Confirmation must consider wire condition, deformation, heat treatment and tests on actual parts.
