The subject of corrosion increasingly impresses one with its international scope and importance. There are several reasons for this beyond the fact that corrosion problems, whether recognized or not, affect all consumers of metals, and therefore enter as an economic factor in the affairs of the community, and particularly its industries. One reason arises from the situation that chemical industry today operates under conditions of higher pressures and temperatures markedly more corrosive to common metal equipment than prevailed several years ago.
Whether a chemical process is practical or impractical is intimately related to rates of corrosion in the process. The power equipment industry likewise is faced with current and impending corrosion problems in the use of higher pressure steam, and with the hot gases employed in the gas turbine.
Another reason derives from conditions inspired by the recent war. The armed services were impressed in no uncertain manner that the...
