Austenitic Steel. ------------------- Will you please instruct a pair of discs, to the attached drawing, in Firth's Austenitic steel, as they would recommend for forged cylinder liners. These are for test in HL's friction test machine, in which we hope to obtain some information on friction under poorly lubricated conditions as with pistons. They will be tested before and after nitro-hardening, and can also be used for corrosion tests. We should like you to obtain from them particulars of composition and heat treatment, and suitability for forging. This steel would seem to have the three advantages as a cylinder material of: (a) ability to be nitro-hardened (b) freedom from corrosion (in contrast with Nitralloy steel) (c) coeff. of expansion nearly as great as aluminium.
