Popis: | 1. Grain refining of overheated steel 00N18K9M5T requires triple water-quench or air-quench from 900–950°C (holding 1h) before quenching from 820°C. 2. For the same strength, the ductility of the unaged steel is somewhat higher than that of the overaged steel. 3. The strength of “light” melts can be increased substantially by increasing the aging time to 16 h at 450°C without lowering the plasticity. |
