Centrifugally Cast Phantom 111 Cylinder Liners. Further to your memos By.15/G.20.1.38. and By.18/G.26.1.38. in order to prove that the works are capable of producing a cylinder liner material similar to that at present in use, we have centrifugally cast a batch of the above liners with a much higher phosphorous content of 1.06 % - the range specified being 0.80 % to 1.10 % . From a sample liner submitted to the laboratory, we have received the information contained in the attached laboratory report. This information includes a complete analysis, maximum and minimum brinell figures on the section, and micro-photographs of the structure of the material in the etched and unetched condition, so that subject to the micros comparing favourably with those of the original material, there is we agree, apparently no reason why expensive wear tests should be run on it.
