159.    BAUKLOH, W.  [Destruction of Cast Iron by Carbon Monoxide Gas Mixtures at High Temperature.]  Metallwirtschaft, vol. 18, No. 3, 1939, pp. 57-59; Chem. Abs., vol. 33, 1939, p. 2864.

                  A cast Fe vessel was destroyed by a hot CO-gas mixture after 1 ½ yr.  The gas penetrated along pores and graphite particles, leaving deposited C.  At 550° the following reaction, catalyzed by Fe, takes place:  2CO→C+CO₂.  Steel is not affected.
