NITRO HARDENED STEEL We believe it has been established that Nitro Hardened Steel is not successful when TEL. dope is used. We have written to U.S.A. to get more particulars about the tests which were made there. At the same time, it is a point we shall have to watch on our engines here. Hs.{Lord Ernest Hives - Chair} | ||
