摘　　要：This paper presents experimentally-obtained data which can be of importance in the design procedure of engineering components made of 1.4057 （X 17CrNil 6-2; AISI 431） steel. In this manner, uniaxialy tests related to determine material mechanical properties and short-time creep behavior were performed. Based on the mentioned tests, ultimate tensile strength, 0.2 offset yield strength and modulus of elasticity at low and elevated temperatures were determined. Also, creep behavior of considered steel was tested for selected temperatures and selected stress levels. According to experimentally determined Charpy impact energy an assessment of fracture toughness was made.This paper presents experimentally-obtained data which can be of importance in the design procedure of engineering components made of 1.4057 （X 17CrNil 6-2; AISI 431） steel.
