ECISS/TC 30/SC 2 - Steel wire for springs

TC - Correction of the coating mass unit in Table 3

This document specifies composition, dimensions and mechanical properties of round and flat wire used for strengthening the bead of all kinds of tyres.

This document specifies the composition, dimensions and mechanical properties of high carbon steel wire for reinforcing high pressure hoses. It is applicable to wire used as a multiple parallel wire braided or spirally wrapped reinforcement in a rubber or synthetic hose which is made to withstand relatively high bursting pressure.

1.1   This Part of EN 10270 applies to oil hardened and tempered spring steel wire made from unalloyed or alloyed steels. They are primarily subject to torsional stresses such as in compression and extension springs and in special cases also for applications where the spring wire is subject to bending stresses such as lever springs.
As a rule unalloyed steels are used for applications at room temperature whereas alloyed steels are generally used at a temperature above room temperature. Alloyed steels may also be chosen for above average tensile strengths.
1.2   In addition to this part of EN 10270 the general technical delivery requirements of EN 10021 are applicable.

1.1   This Part of EN 10270 applies to patented cold drawn unalloyed steel wire of circular cross-section for the manufacture of mechanical springs for static duty and dynamic duty applications.
1.2   In addition to this part of EN  10270 the general technical delivery requirements of EN 10021 are applicable.

1.1   This Part of EN 10270 applies to the grades of stainless steels listed in Table 1, which are usually used in the cold drawn condition in the form of wire of circular cross-section up to 10,00 mm in diameter, for the production of springs and spring parts that are exposed to corrosive effects and sometimes to slightly increased temperatures (see A.1).
1.2   In addition to the steels listed in Table 1 certain of the steel grades covered by EN 10088-3 e.g.1.4571, 1.4539, 1.4028 are also used for springs, although to much lesser extent. In these cases the mechanical properties (tensile strength, etc.) should be agreed between purchaser and supplier. Similarly, diameters between 10,00 mm and 15,00 mm may be ordered against this standard; in this case the parties should agree upon the required mechanical characteristics.
1.3   In addition to this part of EN 10270 the general technical delivery requirements of EN 10021 are applicable.
