Abstract
The reason for the development of low-carbon martensitic steels (LCMS) is the absence of universal and comparatively inexpensive structural iron alloys combining high mechanical properties with processibility. Hardening of LCMS commonly includes heating above Ac 3 (930 – 950°C) and air-cooling. The present paper studies the possibility of heat hardening after heating in the intercritical temperature range, the role of special carbides in realization of structural heredity, the laws of formation of structure, and the properties of commercial LCMS of grades 10Kh3GNM and 12Kh2G2NMFT.
