AISI D3 is a high-carbon, high-chromium cold work tool steel with approximately 12% chromium content. It exhibits:
D3 is more wear-resistant than D2 but also somewhat more brittle, making it suitable for tools requiring high abrasion resistance but lower toughness.
Kuber Multi Metals is the largest stockiest and supplier of HCHCR D3 Steel in flat, square and round bar. We provide steel in all sizes as your requirements. HCHCR D3 die steel is available in flat, square and round shape. Consult our team who will assist you for HCHCR D3 steel query.
D3 Steel having properties of High Carbon 2% and High chromium 12 % tool steel with high wear resistance. Its supply condition is normally annealed to easy machining which recommended hardness is 57-58 HRC after making the dies & tools.
| Property | Value |
|---|---|
| Impact Toughness | 28 J/cm² |
| Hardness | 58-64 HRC |
| Poisson’s Ratio | 0.27-0.30 |
| Modulus of Elasticity | 190-210 GPa |
The physical properties can vary slightly depending on the specific composition and heat treatment of the D3 steel. Its always recommended to refer to the manufacturer’s specifications for precise information.

Heat to 800–850°C, slow cool at max. 20°C/hr to 600°C, then air cool. Hardness after annealing: ~230 HB.
Preheat at 600–700°C. Austenitize at 950–980°C. Quench in oil (small sections may be gas quenched in vacuum).
Temper immediately after hardening. Typical tempering range: 150–350°C. Final hardness: 58–64 HRC.
Shear blades & slitter knives, Punches & dies for blanking and forming, Thread rolling dies, Cold extrusion dies, Drawing & deep drawing tools, Metal forming rolls, Stamping tools for long production runs
AISI D3 tool steel is a high-carbon, high-chromium cold work steel used in applications where very high wear-resistance and high hardness are essential. In its combination of relative abrasion resistance with lower toughness, D3 has a higher chromium content of approximately 12 percent and higher carbide content relative to D2. It offers good heat treatment and dimensional stability, and offers good compressive strength, which makes it superior in shear blades, punches, dies, extrusion tools, and stamping processes, which require a long service life.
