Advanced practices for melting, hot working, and annealing have been developed which enable H-11 to be consistently supplied with a fine uniform annealed structure, as illustrated herein. This steel is readily heat treated to produce a uniformly fine grained microstructure. The structural uniformityresults in longer die life.
