COLD WORK TOOL STEEL (IND/USA/EUR)

Cold work tool steel fall into five groups: water hardening, oil hardening, medium alloy air hardening, high carbon-high chromium and shock resisting. As their name implies, these steels are used in low to medium temperature applications. Highly wear resistant due to the high volume of carbides in the microstructure.

The high carbon and chromium content promotes deep hardening. Hardenability is accentuated by small amounts of tungsten and molybdenum. Dimensional change in hardening is extremely low.

Cold work tool steel is used in the manufacturing of tools used in cold processing of other steels like cast irons and non-ferrous metals.  The operations are diversified as cutting, bending, forming, coining, extrusion, steel wire drawings, wooden work, ceramic pressing, pigment grinding, rock drilling, paper cutting and various other applications.

We can help you choose the right tool steel and heat treatment for the application. What you gain – lower tooling costs, lower maintenance costs and less downtime.
