Popis:	1. High-temperature tests of steel as cast and hot-rolled showed high ductility at 900–1200°C, which ensures high plasticity in hot working. 2. Tempering 1 h at 400–900°C does not lead to embrittlement of samples quenched from 1200–1020°C. The samples are embrittled by prolonged tempering (10 and 100 h) at 600–800°C. 3. Embrittlement is due to the precipitation of the σ-phase at the ferrite-austenite interface. 4. The brittleness is removed by heating 1 h at temperatures above 900°C, which dissolves the σ-phase.
