RHC{R. H. Coverley - Production Engineer}4/BE. 8.7.30. In view of the very much improved performance in the model cranks of the nitralloy material over C.H.N.S. I do not think it is desirable at the moment to machine either of the remaining forgings in C.H.N.S. In the first place we are trying to get some further information from the model cranks as to the best condition in which to use C.H.N.S., and in the second place as pointed out above, it would appear that nitralloy is a much stronger material, and is therefore more desirable from this point of view.
