Abstract
The microstructural features and mechanical properties of type 304 stainless steel castings were correlated with nitrogen contents together with the varying contents of nickel and other composition. Delta-ferrite contents varied with the composition, however, showing relatively lower contents than those predicted by Delong plot. Regression equations were developed among various properties. Tensile strength and abrasive wear were also linearly related to the hardness. Electrochemical measurements showed that the varying chemical compositions and delta-ferrite contents have only a minor effect on the corrosion resistance. Multiple regression analysis was made to explain the contribution of nitrogen and delta-ferrite, which satisfactorily predicted the yield strength, tensile strength, impact energy and abrasive wear. It was shown that the nitrogen caused well-known strengthening effect, and also delta-ferrite was powerful strengthening element.
