Abstract

This paper presents the experimental results of a study investigating the effect of forging temperature on the microstructure and properties of REX 734 austenitic stainless steel. The first part of this paper offers an overview of the physical and chemical properties of implantable stainless steels and their medical applications. The material chosen for the experimental investigation is REX 734 high-nitrogen stainless steel characterized by optimal mechanical properties. The subsequent part of the paper describes the experimental tests of forging REX 734 stainless steel in a temperature range between 950 and 1200 °C. Following the forging process, the microstructure and properties of REX 734 are examined. The experimental results are used to determine optimal hot-working thermal conditions for REX 734 implantable stainless steel in terms of desired microstructure and properties.
