Summary Report on the Heat Treatment of Stockless Anchors

Abstract

Coupons and test castings of suitable dimensions to represent a section of a heavy anchor shank were heat treated by ten different procedures. One lot of castings was made from each of three very similar heats of modified Class B steel. In each lot, a prolonged anneal was used as a control treatment. Methods of sampling, description of testing procedures, data, interpretation of results, conclusions, and recommendations are giving. It was found that prolonged annealing can be replaced by several shorter treatments. Although not recommended for adoption as a specification at present, quenching and tempering give the most desirable physical properties. For expediency and satisfactory physical properties, a single normalizing and tempering treatment is suggested as the most logical treatment.
