A Comparative Study on the Oxidation of Fe-25Cr-7Ni-4Mo and Fe-25Cr-7Ni-2Mo-4W Steels

Abstract:

Stainless steel materials (FeCr and FeCrNi-based alloys) are employed in a wide range of modern applications due to their ability to withstand corrosive environments while maintaining good mechanical properties. Their corrosion resistance originates from Cr-rich oxide layer which serves as a barrier against ion diffusion between the alloy and the ambient phase. Custom steel grades can be designed for specific applications by optimizing their properties throughout alloy composition [1].
