Abstract

1333876 Heat treating hot worked steel STAHLWERKE SUDWESTFALEN A G 8 Feb 1971 4178/71 Heading C7A Hot worked steel is cooled at the rate of 5-25‹C/sec to a temperature of 10-40‹C above the A 1 point, held at this temperature for 1-20 minutes and then quenched to below the Ms point. The treated steel may then be annealed.
