The production of promising thermally stable polymer materials, i.e., aromatic polyamides of Terlom, Phenylone, and polyarylates is associated with the application of solutions and melts of dichloranhydrides of isophthalic and terephthalic acids. Investigations were carried out on the corrosion resistance, in the melts of the dichloranhydrides of the isophthalic and terephthalic acids, of corrosion-resiting austenitic (12Kh18N10T, 10Kh17N13M2T, 08Kh17N15M3T, 06KhN28MDT), austenitic-ferritic (08Kh22N6T, 08Kh18G2N2T, 08Kh21N6M2T), ferritic (08Kh17T, 15Kh25T) steels and alloys, titanium VT1-0, titanium VT5-1 alloy, and welded joints in these materials. The specimens of the corrosion-resisting steels were welded by the electric arc method using the standard filler materials, and titanium and the titanium alloys were welded by argon-arc welding. On the basis of the experimental results, 08Kh21N6M2T steel and 06KhN28MDT alloy are recommended for the construction of equipment working in the melts of the dichloranhydride of the isophthalic acid, whereas equipment working in the melts of the dichloranhydride of the terephthalic acid at 90 C should be constructed from 08Kh21N6M2T steel.
