...Table 2 gives the uniform corrosion rate of the various Ni-Cr-Mo alloys in some standard and non-standard boiling corrosive media. As is evident, overall alloy 59 appears to have the lowest corrosion rate. The lower iron content of alloy 59 also contributes to its excellent corrosion resistance...

... Abstract Within the last decades great efforts were made by the producers of wrought corrosion resistant products to develop new alloys. The materials of construction for modern chemical process industry (CPI) plants, petrochemical and other industries not only have to resist uniform corrosion. New alloys...

... tested can be considered as resistant to uniform corrosion. Adding 1000ppm of fluoride leads to a significant increase in the corrosion rate for the austenitic UNS S31603 (corrosion rate multiplied by 10), the UNS S31726 (by 3) and the superaustenitic UNS N08904 (by 4) grades. For the two grades...
