1.62C 9.7Cr-1.2Mo-0.3V-1.4Ni Low Alloy Steel

This is a high-carbon, high-chromium tool steel with significant cobalt addition (17%), designed to combine extreme hardness with wear resistance and moderate toughness. The composition—dominated by 9.7% Cr, 1.62% C, and notable Mo and V additions—places it in the premium tool steel family, typically used where cutting edge retention and thermal resistance are critical. This material finds application in precision cutting tools, dies, and gauges where the cobalt content provides enhanced red hardness (strength at elevated temperatures), making it particularly valuable for high-speed machining operations and demanding industrial cutting applications.
