Description :
However, it is not only the oil, gas, and chemical industries where Ferralium 255 thrives. Ferralium 255 also provides outstanding resistance to pitting and crevice corrosion in seawater and other chloride-rich environments, making it an excellent material for use in marine environments. This resistance has several contributing factors. The first of these is because the Critical Pitting Temperature of Ferralium 255 exceeds 50°C. At the same time, Ferralium 255 features excellent ductility and impact strength at both ambient and sub-zero temperatures. These, combined with high resistance to abrasion, erosion and cavitation erosion, ensure outstanding resistance. Ferralium 255 was listed in NACE MR 01 75 for sour service. Having gained ASME Approval for Pressure Vessel applications, Ferralium 255-SD50 was tested to the highest degree using tests designed to guarantee that the trade-marked product possesses high integrity, a correct phase balance, and the absence of sigma and other deleterious phases. Ferralium 255 is less sensitive to the formation of these deleterious phases than other super duplex stainless steels.
