Prevention of hydrogen embrittlement of high-strength steel by hydrazine compositions

摘要

Delayed failure of high-strength steel alloys exposed to compositions containing hydrazine is prevented by addition of potassium hydroxide to the composition in an amount at least sufficient to neutralize acidic impurities. The removal of the acidic impurities eliminates evolution of hydrogen and thus avoids hydrogen embrittlement of the high-strength steel alloys.
