SKD61 tool steel is a silicon, chromium, molybdenum, vanadium alloy medium-hot die steel after quenching and tempering treatment has been organized fine, moderate grain martensite, is basically a small carbide distribution, with good mechanical properties, hardenability and good performance, more suitable for manufacturing large size, complex shape of the mold.
 
SKD61 mold steels
1, high-temperature strength and toughness, better wear resistance, easy cutting;
 
2, SKD61 is a very good strength, toughness and heat balance of hot die steel, isotropic product development in recent years with increasingly to the development of high toughness, etc., it can make a longer tool life, better performance stable, and easy processing, heat deformation small.
 
SKD61 tool steel use
SKD61 in aluminum, zinc die-casting mold materials, the most widely used, this steel contains tungsten alloy composition of the high temperature, suitable for hot, aluminum, magnesium, zinc, copper alloy die-casting mold, cutting knives, scissors and forging operation, plastic mold, hot reamers, rolling knives, general hot forging dies, hot bolt mold, heat between the various tools.
