Hastelloy, cladding

Reactor materials. One drawback that could be mentioned is the high corrosivity of iodide. Hydrogen iodide is very corrosive, but the presence of iodide salts makes it even worse. Carbon monoxide will also react with many metals under the reaction conditions (30 bar of CO, 180 °C). Hastelloy-C is an inert material which is used in the laboratory. For the actual plants titanium cladded reactors have been mentioned as a possible solution.

The stainless steel should be carefully selected with respect to martensitic transformation instability under stress or at low temperatures, which causes it to become magnetic and results in appreciable loss. A number of stainless steels were obtained in strip form, and the losses were measured at 4 K. The strips, obtained in the soft (or annealed) condition, ranged in thickness from 50 tm to 250 /xm. The results are shown in Fig. 4. The losses are normalized to a 20-pm thickness, which is the approximate thickness to be used in a ss/Cu clad NbsSn tape. Steels such as 304, 310, and Hastelloy B exhibited losses in excess of... 

PTFE is resistant to liquid chlorine and to both wet and dry chlorine gas up to 200°C. Tantalum, Hastelloy C, PTFE, PVDF, Monel, and nickel are recommended for membranes, rupture discs, and bellows. The materials of construction for heat exchangers and tanks are generally titanium or Ti-clad, rubber-lined carbon steel, PTFE-lined carbon steel to handle wet chlorine gas or aqueous solutions containing chlorine.
