Main characteristics
Compared with steel, this kind of steel has higher strength, wear resistance and hardenability. The critical hardenable diameter in oil is up to ~ the critical hardenable diameter in water is up to ~, but the toughness is But lower
Medium carbon modulated steel cold heading die steel. The steel is moderately priced and easy to process. After appropriate heat treatment, it can obtain certain toughness, plasticity and wear resistance. Normalizing can promote the spheroidization of the structure and improve the cutting performance of the blank with a hardness smaller than that of the blank. Tempered at a temperature of ~℃, the steel has the best comprehensive mechanical properties. The hardenability of this steel is higher than that of steel, and it is suitable for surface hardening treatments such as high-frequency quenching, flame quenching, etc. Later, various parts with higher load-bearing and wear resistance requirements such as gear sleeves, shafts, pins, etc.
