METHOD FOR PRODUCING A COMPONENT FROM AN AIR-HARDENABLE STEEL AND COMPONENT PRODUCED THEREWITH |
摘要 |
A component of an air-hardenable steel composed of (contents in mass %): C<0.20; Al<0.08; Si<1.00; Mn 1.20 to <2.50; P<0.020; S<0.015; N<0.0150; Cr 0.30 to <1.5; Mo 0.10 to <0.80; Ti 0.010 to <0.050; V 0.03 to <0.20; B 0.0015 to <0.0060, with the remainder being iron including the usual elements present in steel, is produced by heating a hot- or cold-rolled steel sheet or steel tube section to a temperature of &thetas;blank=800 to 1050° C. and then forming the sheet or tube into a component in a forming tool. After removal from the tool, the component is cooled down in air while the component still has a temperature above &thetas;removal=200° C. and below 800° C. The component achieves the required mechanical properties during air-cooling. |
