What is Cold Work Tool Steel?
Cold work tool steels are high-carbon alloy steels designed for tooling that operates at or near room temperature, where wear resistance, edge retention and dimensional stability under hardening are the priorities. The category is generally split into three hardening families: high-carbon high-chromium air-hardening grades (D2, D3), oil-hardening grades (O1, O2), and shock-resisting grades (S1, S7) alongside the versatile air-hardening A2.
These grades are stocked in the annealed (soft) condition for machining, then hardened and tempered to a working hardness typically between 54-63 HRC depending on the grade and application.
Each grade below has its own dedicated technical page with full chemical composition, mechanical properties and heat treatment guidelines — use the grades table to jump to the grade that fits your application.

Applications & Uses of Cold Work Tool Steel
- Blanking and piercing dies
- Forming and drawing dies
- Punches and press tooling
- Shear blades and slitter knives
- Gauges and precision measuring tools
- Cold forging and coining dies
- Chisels and hand tools subject to impact
- Thread rolling dies
Choosing the Right Grade
For maximum wear resistance in long production runs, D3 and D2 are the standard choice, with D2 offering a better toughness balance for general die work. Where machinability and dimensional stability during hardening matter most — precision gauges, knives and punches — O1 and O2 oil-hardening grades are preferred. Where tooling faces repeated impact rather than pure abrasive wear, S1 and S7 shock-resisting grades or the air-hardening A2 offer a better toughness-to-wear-resistance balance.
