The present paper deals with analyzing the influence of mechanical parameters of quenched and tempered X20Cr13 Stainless Steel on the LCF properties. Specimens were heated to 1000°C, kept in this temperature for 45 minutes and subsequently quenched in oil to room temperature, then heated to 550°C, 620°C or 700°C (for different specimens), kept in the heat for 15 minutes and cooled to the room temperature, in order to obtain required hardness. Micro-hardness and hardness of the structure in transversal specimen section were measured. The LCF tests were carried out for three different strain amplitudes between 0.5% and 1.5%. Relationships between hardness, strain amplitude and low cycle fatigue life were also determined.
