Lead attack on steels and comparing knowledge with General Motors and Ethyl Export.

General Motors and Ethyl Export seemed to me
to know little more about lead attack than we do. They are not
at all sure that lead bromide doesn't take some part in lead
attack. They reproduce lead attack in the laboratory by
putting samples on a slowly rotating disc. This carries the
samples in an area heated by a lead treated flame and then
cools them. This cycle is repeated continuously and they say
the lead resistance of steels depends considerably on the type
of flame used - oxidising or non-oxidising.

Next week I shall be at the Pennsylvania Hotel,
New York, and shall sail on the 21st.

H.S. Royce.
