Tool Steel Forgings & Castings

Tool steels are engineered for wear, impact and thermal-fatigue resistance in tooling and high-stress industrial parts. Monmet supplies hot-work, cold-work and shock-resistant grades through its network of foundries and forges.

Quick answer

Tool steel is engineered for wear, impact and thermal-fatigue resistance in dies, molds and heavily stressed tooling. Hot-work, cold-work, shock-resistant and plastic-mold families are each suited to a different duty cycle. Monmet supplies forgings and castings through its network of foundries and forges, annealed or hardened to your specification.

Tool Steel

Grade Families

Hot-work, cold-work, shock-resistant, high-speed and plastic-mold tool steels — the specific grade is set by your drawing or purchase order.

Melting & Cleanliness

Melt practice is chosen for inclusion control, which is what governs tool life in heavily stressed dies and industrial tooling.

Heat Treatment

Annealed (delivery), hardened and tempered to the hardness stated on your drawing or purchase order, set by whether the tooling is cold-work or hot-work.

Frequently Asked Questions

Hot-work grades are the general-purpose choice for tooling exposed to repeated heating, balancing hot hardness against thermal-fatigue resistance.

Cold-work grades suit abrasion at ambient temperature; hot-work grades suit repeated heating and thermal shock. Tell us the duty cycle and we will recommend the grade.

Yes — plastic-mold tool steel blocks are supplied pre-hardened to the hardness on your purchase order, ready for direct machining.
