Cold Work Tool Steel Equivalent Chart
Cold Work Tool Steel KS Specifications — 1 sizes
KS D 3753
SKD11 (KS/JIS) = X153CrMoV12 (DIN) = D2 (ANSI): equivalent cold work die steels. Extremely high wear resistance; the global standard material for cold press dies.
Practical Notes
- SKD11 offers excellent wear resistance — standard for blanking and bending dies. HRC 58–62 after quenching.
- Watch for residual stress cracking after wire EDM. Low-temperature tempering (150–200°C) after machining relieves stress.

Key Features
- STD11 (SKD11) representative; Cr 12% + C 1.5% maximizes wear resistance
- HRC 58–62 after quenching; vacuum heat treatment minimizes distortion
- Dispersed high-hardness carbides (Cr₇C₃) enable press die life of hundreds of thousands of shots
Key Applications
Press dies (punch/die), shearing blades, cold forging dies, forming rolls, precision gauges
FAQ
Difference between SKD11 and SKD61?
SKD11 is for cold dies (room-temp pressing); SKD61 for hot dies (die casting, hot forging). SKD11 focuses on wear resistance; SKD61 on thermal shock resistance.
