Ingots from stainless steel 21-4N are studied in the initial condition and after 7-h homogenizing at 1200°C. Compressive tests of specimens cut from surface layers and from the cores of the ingots are performed at 900 – 1250°C. The effect of the initial condition of the steel and of the test conditions on the critical stress of the start of dynamic recrystallization is determined. The conditions of formation of dangerous cracks in the ingots are considered.
