Abstract
This paper deals with the results of testing of mechanical properties of nickel free austenitic stainless steel depending on the content of delta ferrite. The appearance of delta ferrite is caused by different ratios of alphagen and gammagen alloying elements, and its appearance is greatly influenced by the method of production, as well as subsequent mechanical processing and heat treatment. Nickel free austenitic stainless steels were manufactured using an induction furnace by adding nitrided ferroalloy under atmospheric pressure. Mechanical properties investigation and microstructural analysis of forged and solution annealing ingots were performed for different nitrogen content. Analysis of microstructure was done by optical microscopy, whereas tensile tests were performed for characterization of mechanical properties.
