THAMES HOUSE, MILLBANK LONDON, S.W.1 Telephone: VICTORIA 1441 Head Office: 135 EAST 42ND STREET NEW YORK, U.S.A 12th January, 1937. Messrs. Rolls-Royce Ltd., Experimental Department, Nightingale Road, DERBY. Your ref: Rm {William Robotham - Chief Engineer} /Swdl. {Len H. Swindell} 10/JH. Dear Sirs, For the attention of Mr. L. H. {Arthur M. Hanbury - Head Complaints} Swindall. With further reference to your letter of the 16th December, we quote herewith an extract from a letter we have just received from Messrs. Thompson Products, Inc. of Cleveland:- "Many thanks for your letter of December 17, together with Rolls print No. EB-2970. We are giving you the analysis of XCR herewith: Carbon .40 - .50 Manganese 1.00 Max. Silicon .60 Max. Chromium 24.00 - 25.00 Nickel 4.50 - 5.00 Molybdenum 2.50 - 3.00 We will make these valves hardened all over to 50-60 scleroscope, which is our standard practice. This material is proving to be an excellent automotive steel and ranks second to Stellite in corrosion resistance. I am entering the order for 12 valves made to this print." This, we think, is self-explanatory, and we will forward the valves to you immediately they come to hand. Yours faithfully, F. {Mr Friese} R. {Sir Henry Royce} BANKS. BB | ||
