Optimization of Heat Treatment of Steel with Enhanced Thermal Resistance

摘要

The work is dedicated to the development of the optimal technological process for the manufacture of hot stamping dies and die casting molds made of steel grade 4X5MF1C, in order to ensure the required performance characteristics. The mode of hardening heat treatment of this steel grade was established, which allows to recommend it as a heat-resistant structural material for metal products with the required yield strength 00.2 within 750 to 1000 MPa.
