High Duty Alloys Limited, in regard to the bearing which we sent to them which seized on an engine during experimental running. You will observe that Messrs. High Duty Alloys Ltd., strongly recommend the use of a forged material for this purpose as against the extruded material which we have so far used. The quantity of forged bar made by Messrs. High Duty Alloys Limited, has already been ordered and as you see they hope to make delivery within seven days. BY/EM. | ||
