Die & tool steel
Reviewing tool life and processing conditions
We review sourcing for cold-work die and tool materials such as SKD11. Application, heat treatment, hardness, structure and surface requirements define the requested delivery condition.

Product & application
Hardness alone is not enough to select a tooling material. We review whether wear, cracking, distortion or chipping is the main concern, alongside delivery condition, heat treatment and machining allowance. High-speed and cold-work die steels are separate families. Changes from a specified grade require customer approval.
- Supply forms
- Round/square stock · cut material · machining allowance by agreement
- Application examples
- Cold-forming dies, shearing dies, forming rolls and wear-resistant tooling
Define the supply conditions.
These are specification inputs for quotation review. Actual availability, minimum quantity and lead time are confirmed by grade and size.
- Condition & surface
- Annealing, hardness, structure and heat-treatment requirements
- Dimensions & order
- Bar/block dimensions, machining allowance and surface-defect criteria
- Inspection & documents
- Specify mill certificates, tests, traceability and customer approvals. Document availability, cost and timing are reviewed.
Representative grades & review scope
| Family | Representative grades / review basis |
|---|---|
| Cold-work tool steel | SKD11 |
| Other tool steels | Review by drawing, required service life and heat treatment |
Grades and forms are inquiry examples. Inventory, availability, dimensions, quantity, inspections and lead time are confirmed at quotation.
JIS names are used as a reference. They do not automatically establish equivalence to other standards or certification. Agree the applicable standard, edition and product requirements before ordering.
Information for quotation & technical review
- Tool application and main life-limiting issue
- Specified grade and standard
- Annealing, hardness, structure and treatment
- Dimensions, machining allowance and surface criteria
- Internal-quality inspection, documentation and schedule
If your drawing or specification is not complete, tell us the intended process and function. We can start by clarifying the information needed for review.
