Compositions and compounds to minimize hydrogen charging and hydrogen induced cracking of steels

摘要

The subject matter of this invention is directed to compositions and compounds to minimize hydrogen charging and hydrogen induced cracking of steels comprising, in one embodiment, a propylene diamine compound and in another a carrier and propylene diamines. Preferably, the composition of that embodiment is comprised of a hydrocarbon carrier and 1,3 propylene diamines. Alternatively, compositions of the present invention may be comprised of a carrier and octadecyl trimethyl ammonium bromide. In addition, where the environment dictates, the composition of the present invention may be comprised of a carrier, at least one 1,3 propylene diamine and octadecyl trimethyl ammonium bromide.
