Category:
Medium-High Carbon Steel
Product Description
SK85 (SK5) steel is Japanese high-grade carbon tool steel, cold work die steel, high carbon steel with a mass fraction of carbon above 0.80%. SK85 (SK5) steel hardness after quenching is 50~60HRC. It has high hardness, excellent wear resistance, and easy spheroidization.
Due to its workability, hardenability and cost-effectiveness, SK85(SK5) material widely used in a wide range of tools (such as utility knives, scalpel blades, long edged tools, cutting tools etc.).
