Steel wire for mechanical springs - Part 3: Stainless spring steel wire; German version EN 10270-3:2011

Overview
Springs shall absorb oscillating or shock-type loads (vehicle springs) or store energy under static load (safety valves, vehicle brakes). Stainless springs are used where a contact with corrosive media may additionally develop. They are also used at elevated temperatures of up to 250 °C. In the same manner as other stainless steels, chromium, nickel and molybdenum are the main components of stainless springs. The finished springs are stress-relieved or in the case of steel 1.4568, precipitation-hardened in order to increase the yield strength and tensile strength compared to the cold-drawn condition. These heat treatments will also reduce the internal stresses in the wire produced by drawing and forming of the springs. For this purpose, the finished springs have a high elastic limit and fatigue strength for their intended use. The committee responsible for this standard is a mirror committee which consists of representatives of the FES, NAD and the Springs Standards Committee under the leadership of the Iron and Steel Standards Committee (FES).
