ABSTRACT:
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.
