Ferralium® alloy 255
Check up to five results to perform an action.

Ferralium® alloy 255 (UNS S32550) Fe 62, Cr 25.5, Ni 5.5, Mo 3.4 Cu 2.0, Mn 1.6, Si 0.7, N 0.2

Industrial and Marine Applications Continue Growing Rapidly for Alloy 255

Alloy 255 is finding many cost effective applications in the chemical, marine, metallurgical, municipal sanitation, plastics, oil and gas, petrochemical, pollution control, wet phosphoric acid, paper making and metalworking industries.

Called "super" because it is more alloyed than ordinary stainless steels and has superior corrosion resistance, alloy 255 is being used in areas where conventional stainless' are inadequate or, at best marginal. One good example s in the paper industry which was hit with an epidemic of corrosion problems when environmental laws forced recycling of process liquids In closed systems, chemicals such as chlorides can build up to highly corrosive concentrations over time. Paper makers have found that ordinary stainless equipment, which had previously given good service, was no longer adequate for many applications.

Si 0.7, N 0.2 Duplex alloy with a high strength to weight ratio, with superior abrasion and cavitation resistance. Resistance to chloride SCC, as well as crevice corrosion and pitting. Good ductility with a high fatigue strength in marine applications. Twice the yield strength of Alloy 20, and stronger than Duplex 2205. An excellent 40 °C critical pitting temperature (ASTM G48-Method A), twice that of Alloy 2205.
