Type of article: Article

Summary

12 TOOL STEELS, 3 STAINLESS STEELS, AND 4 OTHER STEELS, WERE SUBJECTED TO CRYOGENIC TREATMENTS TO DETERMINE THE DIFFERENCE BETWEEN A 189 K SOAK AND A 77 K SOAK IN IMPROVING THE ABRASIVE WEAR RESISTANCE. THE TOOL STEELS EXHIBITED A SIGNIFICANT INCREASE IN WEAR RESISTANCE AFTER THE SOAK AT 77 K AND A LESS DRAMATIC INCREASE AFTER THE 189 K SOAK. THERE WAS AN INCREASE IN THE WEAR RESISTANCE AFTER THE CRYOGENIC TREATMENT FOR THE STAINLESS STEELS, BUT THE DIFFERENCE BETWEEN THE TWO TREATMENTS WAS LESS THAN 10%. THE PLAIN CARBON STEEL AND THE CAST IRON SHOWED NO IMPROVEMENT AFTER EITHER CRYOGENIC TREATMENT.
