| Description: |
Tool steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. Their suitability comes from their unique toughness, resistance to abrasion, ability to hold a cutting edge, and resistance to deformation at elevated temperatures (red-hardness). Tool steel is also useful for making objects intended to resist tampering (such as locks and hinges) so they cannot be defeated with normal tools.
With a carbon content between 0.7% and 1.4%, tool steels are manufactured under carefully controlled conditions to produce the required quality. Tool steels are made to a number of grades for different applications. Choice of grade depends on, among other things, whether a keen cutting edge is necessary, as in stamping dies, or whether the tool has to withstand impact loading and service conditions encountered with such hand tools as axes, pickaxes, and quarrying implements. In general, the edge temperature under expected use is an important determinant of both composition and required heat treatment. The higher carbon grades are typically used for such applications as stamping dies, metal cutting tools, etc..
Tool steels are also used for special applications like injection molding, because the resistance to abrasion is an important criterion for a mold that will be used to produce hundreds of thousands of parts. Below mentioned are some of the tool steels we deal with:
- High Speed Steel,
- High Carbon / Chromium Steel,
- Hot Die Steel,
- Oil Hardening Non Shrinking Steel with Tungsten
