|---|---|
| Product form | Forging |
| Standards and order reference | Customer-approved Chinese producer or technical specification; LD is a commercial grade designation and must be supported by defined chemistry and property limits. |
| Dimensions and tolerances | Finished or forging dimensions to drawing; forging ratio, machining allowance and tolerances agreed during technical review |
| Surface and supply condition | As-forged, shot-blasted, rough-machined, fully machined 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 | cold-heading and cold-extrusion dies, heavy-duty punches, forming and trimming tools, high-load wear components |
| 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 LD as forging for cold-work tooling and engineered wear applications. Available production routes include open-die forged blocks, discs, rings, shafts or drawing-specific near-net shapes, subject to grade and mill capability. Every order is reviewed against the drawing, finished tool size, machining allowance, heat-treatment plan and documentation requirements.

Grade Characteristics
LD is a high-strength, high-toughness cold-work die-steel designation used for tools exposed to high contact stress, wear and a risk of chipping.
- High strength and useful toughness for demanding cold work
- Resistance to chipping under properly designed and treated tooling conditions
- Suitable for high-load forming and heading applications subject to the approved grade route
Ordering note: LD supply varies by producer. Confirm the full datasheet, melt route, cleanliness, annealed condition and heat-treatment targets instead of assuming a universal composition.
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:
- cold-heading and cold-extrusion dies
- heavy-duty punches
- forming and trimming tools
- high-load wear components
- large die blocks, rings, heavy inserts, shafts and high-load tooling components
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 open-die forging, heat treatment, saw cutting, rough machining, boring and ultrasonic inspection where specified. 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.

Frequently Asked Questions
Can you cut LD forging 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 LD 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 LD 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.
