Introduction
EN 10268
is a European standard covering cold rolled flat steel products with high yield
strength for cold forming applications. These steels are produced using
controlled rolling and micro-alloying techniques to achieve an excellent
combination of strength, formability, weldability, and dimensional accuracy.
EN 10268
steel sheets, plates, coils, and strips are extensively used in automotive
manufacturing, transportation equipment, construction machinery, agricultural
equipment, and industrial fabrication. Their high yield strength enables
manufacturers to reduce component weight while maintaining structural
performance and durability.

Notes
a.
These additional elements may be used individually or in combination where they
appear in the definition of the steel within the composition limits indicated.
Vanadium and boron may also be added. However, the sum of the contents of these
four prescribed elements shall not exceed 0.22%.
b. For all interstitial free (Y)
grades, Nb may be added alternatively or in combination with Ti. For all grades
containing "I" in the designation, Ti can be substituted by Nb or B.
