Abstract

A cold-workable, corrosion-resistant ferritic chromium steel, comprising 0,005 to 0.1% of carbon, 0.2 to 1.2% of silicon, 0,4 to 2.0% of manganese, 8 to 20% of chromium, 0.1 to 1.2% of molybdenum, 0.01 to 0.5% of nickel, 0.5 to 2.0% of copper, 0.001 to 0.6% of bismuth, 0.002 to 0.01% of vanadium, 0.002 to 0.1% of titanium, 0.002 to 0.1% of niobium, 0.15 to 0.8% of sulfur and 0.001 to 0.08% of sulfur and 0.001 to 0.08% of nitrogen, remainder iron including smelting-related impurities, is suitable as a material for precision-mechanics applications and precision appliances, in particular spinning and spraying nozzles, tips and heads for writing implements, on account of its good mechanical processibility, in particular its good machinability, its good wear resistance and surface quality.
