Damage of a heat-treatment retort by metal dusting attack

In this forum readers will be able to present practical problems for discus sion. It is envisaged that these contributions will include not only discus sion of general problems and as yet unexplained incidents of corrosion but that suggested remedies will also be presented and discussed. It is hoped t hat this exchange of knowledge and experience will become a permanent featu re of this periodical. We are particularly anxious that both Senior Scienti sts and those with more practical experience will make use of this forum to exchange information, problems and potential remedies.
