The Strength and Ductility of Steel Castings at Hot Tearing Temperatures - 1250-1400 Degrees Centigrade

Abstract

Equipment has been devised and constructed to test cast steel at temperatures (1250 deg C. to 1400 deg C.) near the solidification temperature of steel. This equipment consists of a small type tensile machine operating against a calibrated spring attached to the mold. A test bar has been developed which shows a uniform temperature throughout its gage length. Preliminary testing has established the nature of existent variations in results and the shape and trend of tensile strength and ductility (elongation) curves.
