Machinability: P20 tool steels have excellent machinability at about 80% that of water hardening steels. Heat Treatment: P20 tool steels are heated to 871-899°C (1600-1650°F) in the carburizing medium during the carburizing process. After being carburized, these ...
D2 Tool Steel make for knife is a versatile high-carbon, high-chromium, air-hardening tool steel that is characterized by high attainable hardness
Unexpected stretched grains formed at the traverse speed of 40 mm/min under the influence of material flow created by the tool shoulder from advancing to retreating side in the stir zone. The bimodal structure formation in the interstitial free steel layer of composite resulted in work hardening ...
Heat treating realizes stress as a result of hardening, depending upon the chemistry of the metal being treated. Heat treating is also used for tempering, quenching, normalizing, and solution annealing.HONING & TURNING During the honing/turning process, an abrasive ...
Hardening – Heat to 890 – 960oC for a time commensurate with ruling section and quench in Water. Tempering – Re-heat to 590oC Minimum as required, dependent on final required properties. Hold for a time commensurate with the ruling section and cool in still in air ...
The influence of the smoothing force, the tool radius, the machining speed, and the supply on the distribution of azimuthal and axial residual stress, the microhardness, and the depth of strain hardening is analyzed for the machining of 30ХГСН2А-ВД steel by ASB-1 synthetic diamond. ...
