摘要
High strength hardenable corrosion-resistant spring steel consists of (in wt.%): 6.0-9.0 nickel, 11.0-15.0 chromium, 0.1-0.3 titanium, 0.2-0.3 beryllium, and a balance of iron. The steel has a martensitic temperature Ms of at least 130 deg C and a ferrite content of less than 3%. An Independent claim is also included for a process for the production of spring steel. Preferred Features: Up to 50% of the nickel content can be replaced by cobalt. Up to 35% of the chromium content can be replaced by molybdenum and/or tungsten.
