SKD11 Tool Steel: Cold-Work Dies and Cross-References

SKD11 is a Japanese cold-work tool-steel designation. Material reference.

Cold-Work Dies and Cross-References

Treat comparisons with D2 as a standards review rather than an automatic substitution. For a stamping die, document whether the problem is wear, galling or chipping and check clearance and workpiece variation before changing the material.

Manufacturing and acceptance checks

Request the governing JIS specification and mill certificate. Define hardness, distortion allowance and whether coating follows grinding. Ask how the supplier will preserve critical edge geometry through treatment and finishing; approve a trial with a measurable wear limit and an agreed production run length.
