Heat-treatable steels, alloy steels and free-cutting steels — Part 6: Hot-rolled steels for quenched and tempered springs
NOTE 1 Table 4 only considers steels that have gained certain international importance. This does, however, not mean that these are available in all industrial countries. In addition, a great number of other steels are specified in regional and national standards.
NOTE 2 Non-alloy steels also for the production of springs are covered by the wire rod specification in ISO 16120-4.
NOTE 3 International Standards relating to steels conforming with the chemical composition requirements in Table 4, but supplied in other product forms or other treatment conditions or intended for special applications, are given in the bibliography.
