Overview

EN 1564:2011 (CEN) - Founding: Ausferritic spheroidal graphite cast irons - defines grades and requirements for ausferritic spheroidal graphite cast iron (also known as austempered ductile iron, ADI). The standard classifies these cast irons by mechanical performance and hardness, specifies sampling and test methods, and gives guidance on structure and hardness ranges. It applies mainly to castings produced in sand moulds (or equivalent thermal behaviour) unless otherwise agreed.

Key topics and requirements

• Grades and classification
  • Five primary grades defined by mechanical properties measured on machined test pieces prepared from cast samples.
  • Two additional grades (Annex A) classified by hardness for high abrasion resistance (e.g., mining, earth-moving components).
• Mechanical testing and sample types
  • Mechanical properties are evaluated using tensile tests, Charpy impact tests, and Brinell hardness tests on test pieces machined from cast samples or from samples cut from a casting.
  • Designation and testing are referenced to a representative wall thickness (designation is based on samples of 25 mm thickness unless agreed otherwise).
  • Sample formats: separately cast, side-by-side, and cast-on samples.
• Microstructure
  • Requirements for graphite (spheroidal/nodular) structure and ausferritic matrix (result of austempering) are specified; microstructure affects strength and toughness.
• Documentation and order information
  • Purchasers should specify the standard number, material designation, relevant wall thickness and any special requirements at order placement.
• Limitations
  • EN 1564 does not provide technical delivery conditions for castings (see EN 1559 series). Grades in Annex A are not intended for pressure-equipment applications unless explicitly allowed by product standards.

Applications and practical value

• Used where a combination of high strength, toughness, wear resistance, and improved mechanical performance over conventional ductile iron is required.
• Typical applications: heavy-duty components in mining, construction and earth-moving equipment, wear parts, and structural castings where ausferritic microstructure (ADI) provides superior properties.
• Enables foundries, metallurgists and specifiers to standardize material selection, testing, and acceptance criteria to ensure consistent performance.

Who should use this standard

• Foundries and casting manufacturers
• Materials and metallurgical engineers
• Quality and inspection personnel
• Design engineers and purchasers specifying ADI castings
• OEMs for heavy equipment and wear-resistant components

Related standards

• EN 1560 (designation system), EN 1559‑1 / EN 1559‑3 (technical delivery conditions)
• EN ISO 6892‑1 (tensile test), EN ISO 148‑1 (Charpy impact), EN ISO 6506‑1 (Brinell hardness), EN ISO 945‑1 (graphite classification)
• Annexes in EN 1564 provide additional guidance on sampling, hardness ranges, machinability and pressure-equipment relationships.
