Properties of 1.2210 Tool Steel
1.2210 alloy steel is characterized by a maximum hardness of 220 HB (approximately 750 N/mm²) and a thermal conductivity of 33 W/m K at 100 °C. Its high carbon and chromium content contribute to its strength and durability.
Forging of 1.2210 Silver Steel
The forging process for DIN 1.2210 steel is designed to optimize its mechanical properties and refine its microstructure, thus enhancing its overall performance in applications.
Heat Treatment
Silver steel 1.2210 can be treated by various heat treatment processes like soft annealing, hardening, and tempering to achieve desired properties.
- Soft annealing is done at 710 to 740 °C for about 2 to 5 hours with controlled cooling.
- Hardening at 780 to 840 °C followed by quenching in water or oil to achieve a hardness of 64-66 HRC.
- Tempering involves slow heating and a minimum time in the furnace.
Applications
Due to its properties, 1.2210 tool steel is commonly used for small turned parts, core pins, punches, and engraving tools. It is also favored for applications requiring polishing, etching, EDM, nitriding, and hard chroming.
