Welding Duplex Steel Type X2CrNiMoN25-7-4 with Analysis of Ferrite Content Measurements in Welded Joints

Abstract:

The paper presents tests results of mechanical properties, hardness measurements, microstructure and the content of ferrite with the use of ferrite meter (feritscope) FMP30 and quantitative metallography technique with the use of Met-Ilo program in welded joints of steel X2CrNiMoCuWN25-7-4 with the use of TIG method. On the basis of achieved results of tests it was concluded that the applied technology of welding was correct and the usefulness as well as limitations of both methods were proved in the assessment of ferrite and austenite content in welded joints from duplex steel.
