Abstract

140,823. National Malleable Castings Co., (Assignees of Kranz, W. G.). May 21, 1915, [Convention date]. Annealing and tempering.-A steel containing about 1.3-1.6 per cent of manganese is heattreated by heating it under automatically controlled conditions to about 825-900‹ C., quenching, reheating to about 550-600‹ C., and cooling slowly in air.
