DETERMINATION OF DELTA FERRITE IN AUSTENITIC STAINLESS STEELS
<p style="text-align: justify;">Microstructure of an austenitic stainless steels is primarily monophasic, i.e. austenitic. However, the chemical composition of steel can affect on precipitation of a delta ferrite. The presence of the delta ferrite in austenitic stainless steel has a beneficial or detrimental effect on mechanical properties (impact and tensile) as well as on weldability and corrosion resistance. This paper presents some methods of determining the content of delta ferrite in austenitic stainless steels as well as in weld metal.</p>
