✦ Synopsis

very little appears to have been published regarding the properties of the metal thus cast.

Opportunity was given to the Bureau of Standards to examine in detail the physical and chemical characteristics of six centrifugal castings made by the Millspaugh process. The results are interesting in showing what may be expected from such metal as compared with the product of the more familia.r manufacturing processes. The advantages to be expected from centrifugally cast steel are physical soundness and freedom from chemical segregation and thus the elimination of waste metal to be discarded, which last is always a very important factor in other processes of manufacture. For certain shapes forging and boring operations may be eliminated. The investigation shows that highly satisfactory castings which are physically sound and free from serious segregation may be produced by the centrifugal method. It is shown that the properties of these castings can be imp,roved greatly by subsequent heat treatment such that the metal may be p.ut in a condition to compare favorably with metal that has been forged.
