Tool Steel Specification and Information
The term tool steel is a generic description of steel which has been developed specifically for tooling applications. Generally speaking, Tool steel are known for their distinctive toughness, resistance to abrasion, their ability to hold a cutting edge, and/or their resistance to deformation at elevated temperature (red-hardness). Some of the operations that tool steel are used in include Drawing, Blanking, Mold Inserts, Stamping, Metal Slitting, Forming and Embossing, although they are not limited to just those areas.
Tool Steel are produced in the annealed condition for ease of machining. After machining, the steel is heat-treated and quenched depending upon the type of steel being used. The heat treating and quenching operations increase the toughness and strength of the material. There are three classes of tool steel generally available in the market today – cold work, hot work, and high speed steel.
Cold Work steel have high strength, hardenability, impact toughness, and wear resistance. As the name would imply, they are used in environments with lower operating temperature, typically at 400° or less. The materials that we carry that fall into the Cold Work category are O1, A2, D2, >S7 and W1.
Hot work steels have many of the same properties of cold working steel, with the added advantage that that those properties are retained at elevated operating temperatures where the tool literally becomes red-hot.
High speed steel have all of the properties listed above, but retain those properties in operating areas where the temperatures exceed 1000° F.
