Austenitic spring stainless: 600 MPa annealed, cold rolled to 1 300–2 200 MPa for springs and spring clips.

Strength comes from cold rolling, which also makes it slightly magnetic. EN 10151 orders strip by tensile class (+C850 to +C1900); the guaranteed ranges of each class are not yet sourced here.
