Examination of Four Experimental Heats of Armor Plate. Heats H640, H668, H669 and H670

Abstract

The macroetched sections indicate a reasonably clean steel except for heat H640 which contained excessive non-metallics. The McQuaid-Ehngrain size is medium fine. The Jominy hardenability of heats H640 and H669 is about 50 R. C. at the quenched end and 30-35 at the opposite end. That of the remaining two heats is only 45 and 20 respectively.
