Grade Characteristics
SKD11 is a JIS high-carbon, high-chromium cold-work tool steel widely used for dies and cutting tools requiring high wear resistance and good hardenability.
- High abrasive-wear resistance
- Good through-hardening response for suitable sections
- Established choice for precision cold-work dies and cutting tools
Ordering note: SKD11, D2 and SLD occupy related application space but are not automatically interchangeable. Order against the required JIS limits and approved process route.
Typical Applications
The correct grade and hardness must be selected from the actual failure mechanism—abrasive or adhesive wear, edge chipping, gross cracking, plastic deformation or dimensional change. Typical enquiries include:
- blanking and piercing dies
- cold-forming and drawing dies
- shear and slitter blades
- gauges, rolls and wear parts
- punches, shafts, rolls, pins, cutters and cylindrical tooling inserts
Delivery Condition and Processing
Material is normally quoted in an annealed machining condition unless the purchase order requires another approved condition. Available services can include saw cutting, peeling, turning, centerless grinding, drilling and preparation of near-net blanks. Requested decarburization allowance, machining stock, grain-flow direction and test locations should be shown on the drawing.
Heat treatment is not one universal cycle. Austenitizing, quenching, tempering, sub-zero treatment and surface coating must follow the actual certified grade, section size, furnace capability and final hardness requirement. Obtain approval before substituting a related grade.
Inspection, MTC and Traceability
The inspection plan may include positive material identification, chemical-composition review, annealed hardness, dimensions, straightness or flatness, visual surface inspection, decarburization checks, and ultrasonic testing where section size and service criticality justify it. Third-party inspection can be coordinated when stated before quotation.
Specify EN 10204 3.1 certification or the required certificate type, heat and lot traceability, marking, packing, country-of-origin requirements and any approved-mill list in the RFQ. Final compliance is defined by the purchase order, approved drawing and issued mill documentation.
How to Request a Quote

Frequently Asked Questions
Can you cut SKD11 round bar to size?
Yes. Cutting and machining options depend on size, tolerance, quantity and delivery condition. Send a drawing or finished dimensions so machining allowance can be reviewed.
Is SKD11 supplied with an MTC?
Certification can be supplied as ordered. State EN 10204 3.1 or another required certificate type and any authenticated-producer requirement before quotation.
Can SKD11 be substituted with a related cold-work grade?
Only after engineering and customer approval. Similar application groups can have different chemistry limits, carbide structures, heat-treatment schedules, dimensional response and trademark status.
What information is needed for heat treatment?
Provide the certified grade, section size, target hardness, service failure mode, dimensional requirements and any coating or EDM operations. The heat treater should use the governing standard or current producer datasheet.
