... to the reduced molybdenum content, the effect of which can only be partly compensated for by the tungsten addition, it is inferior to alloy UNS N10276 in strongly reducing media and in conditions of extreme crevice corrosion attack. alloy UNS N06058 Ni-Cr-Mo alloys pitting corrosion chemical process industry...

... localised corrosion pitting chemical process industry FGD acids INTRODUCTION As is to be expected, nickel-chromium-molybdenum alloys combine the good resistance to corrosion of nickel-molybdenum alloys under reducing conditions with the good resistance to corrosion exhibited by nickel-chromium alloys...

... in chemical process industries (hereafter, CPIs) were also observed. METI (the Ministry of Economy, Trade and Industry, Japan), which is the ministry in charge of the safety of chemical plants in Japan, has become deeply concerned regarding this situation. METI officially released its “Interim Report on 100...

...Abstract In the Chemical Process Industry every type of the C-series (NiCrMo Alloys) is used, for example as pipes and vessels. Because of the continuously increasing corrosion resistance requirements, these materials are being replaced by higher alloyed types such as Alloy 22 or Alloy 59...

... i Abstract The paper describes several approaches to perform computer simulation of corrosion occurring in the chemical process industries. While the present state of the art does not permit simulating all modes of corrosion observed in process systems, useful insights can be gained at the design...

.... Numerous important applications are exemplified. In most cases the selection of a duplex steel has been a result of the combination high strength - excellent corrosion resistance. In the pulp & paper industry the most interesting use is as vessel material in digesters. For chemical process industry...

... chemical process industry chloride SCC INTRODUCTION The duplex stainless steels (SS) offer an excellent combination of corrosion resistance and economy. Figure 1 shows the relative cost vs. equivalent chloride pitting resistance for several austenitic and duplex stainless steel grades. The duplex SS...
