Abstract
The structure and mechanical properties of a number of experimental 12% chromium steels of the ferritic-martensitic class are studied, whose prototypes are two domestic heat-resistant steels EP-450 (12Kh12М2BFR) and EP-823 (16Kh12МVSFBR). The possibility is demonstrated of using isothermal hardening for controlling the quantitative ratio of martensite and ferrite in test steel structure, characterized by considerable austenite thermal stability. It is established that ferrite content in the original steel structure has a specific unfavorable effect on high-temperature strength.
