| -2- Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation}5/MH{M. Huckerby}, 1.7.39. A.104 Nickel Molybdenum. Analysis same as A.103, but Chrome nil and Molybdenum .7%. According to RHC{R. H. Coverley - Production Engineer}/Vs.{J. Vickers} the best known material for cylinder blocks, but more expensive than A.103. SERIES B. (Centrifugally Cast). B.106 Phosphor Chrome. .70 - .80% Phosphorus. .30 - .40 Chromium. Unheatreated with no nickel content. B.107 High Phosphorus Chrome. Phosphor raised to 1.0% Recommended by By.{R.W. Bailey - Chief Engineer} to replace Sheepbridge Stokes on Ph.III. Rather a brittle material for a dry liner. B.108 "Austenitic" Nickel Copper Chrome. With 13.0 - 15% Nickel 2% Chromium 6% Copper. RHC{R. H. Coverley - Production Engineer}/Vs.{J. Vickers} states in a memo of last year:- "The best known corrosion resisting alloy iron". His recommendation for a centrifugally cast liner. | ||
