Sažetak

Specimens of high chromium creep resistant steel were tempered at 800 °C for different times and examined in SEM. After short tempering stringers of cementite particles are formed at ferrite grain boundaries. By longer tempering, the content of chromium and molybdenum increase up to Cr₁₈Fe₃Mo₂C₆ and the number of stringers decreases what gradually increase the creep rate.
