|---|---|
| Product form | Plate |
| Standards and order reference | Customer-approved producer or supplier specification; 8566 is treated here as a commercial/proprietary designation rather than a universal standard grade. |
| Dimensions and tolerances | Thickness, width and length to enquiry; tolerances and machining allowance agreed before production |
| Surface and supply condition | Black/as-rolled, shot-blasted, milled, precision-ground or customer-specified |
| Inspection options | Chemistry, hardness, dimensions, visual inspection and ultrasonic testing where ordered. |
| MTC and traceability | EN 10204 3.1 MTC or agreed certificate type with heat/lot traceability. |
| Typical applications | heavy-duty punches and dies, cold-forming and trimming tools, impact-loaded tooling inserts, industrial knives for suitable duty |
| RFQ checklist | Send grade/specification, dimensions, quantity, condition, inspection, documentation and delivery destination. |
Final compliance is defined by the purchase order, approved drawing and issued mill documentation. Availability is confirmed for each grade, size and production route.
SAKY METAL supplies 8566 as plate for cold-work tooling and engineered wear applications. Available production routes include hot-rolled, forged or sawn plate; optional milling, grinding and custom-cut blanks. Every order is reviewed against the drawing, finished tool size, machining allowance, heat-treatment plan and documentation requirements.

Grade Characteristics
8566 is a commercial cold-work tool-steel designation requested for tooling where a high-toughness property profile and resistance to premature cracking or chipping are important.
- Specified for demanding tooling where toughness is a primary selection factor
- Applicable to combined impact and wear service after qualified heat treatment
- Can be supplied in multiple stock forms subject to authenticated mill availability
Ordering note: The short designation 8566 is not sufficient for technical release. Attach the approved datasheet, producer identity, chemistry limits, hardness target and heat-treatment route to the RFQ.
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:
- heavy-duty punches and dies
- cold-forming and trimming tools
- impact-loaded tooling inserts
- industrial knives for suitable duty
- die blocks, bolster and wear plates, large inserts and flat tooling blanks
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, waterjet cutting where suitable, milling, grinding, drilling and preparation of six-side-machined 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
- State the exact grade and governing standard or approved producer datasheet.
- Send thickness, width and length to enquiry; tolerances and machining allowance agreed before production.
- Define quantity, delivery condition, surface, machining allowance and final application.
- List hardness, ultrasonic, cleanliness, certification, marking and third-party inspection requirements.
- Provide the delivery destination and required schedule.

Frequently Asked Questions
Can you cut 8566 plate 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 8566 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 8566 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.
