Metal Science and Heat Treatment Aims and scope

Conclusions

  1. 1.

    Addition alloying of steel of the 0Kh6N8M7S type with nickel and molybdenum (1%) lowers MS by 30°, and alloying with chromium 40°.

  2. 2.

    The temperature for complete solution of intermetallic hardening phases should be 1100–1150°.

  3. 3.

    Steel of the 0Kh6N8M7S type has high heat resistance and can be used for pressing tools operating at elevated temperatures.
