First Partial Report on the Heat Treatment of Stockless Anchors

Abstract

Three 10 x 10 x 20 inch blocks which approximate the average section of large stockless anchors were cast of Class B steel, which is at the present time used in the manufacture of anchors. One casting was annealed according to existing specifications and the other two were given shorter heat treatments. It was found that the present heat treating time of 64 hours could be reduced about one-half by using a different heat treatment and that better physical properties throughout the test castings could be obtained. Micrographs and macrographs, density measurements, and the results of low temperature impact tests are also presented.
