Founding - Malleable cast irons

This document defines grades and the corresponding requirements for malleable cast irons.
This document specifies five grades of whiteheart malleable cast iron and nine grades of blackheart malleable cast iron, based on mechanical properties measured on cast samples (which are test pieces).
This document specifies Brinell hardness values determined only when these values are requested by the purchaser.
This document does not cover technical delivery conditions for malleable cast iron castings. Reference should be made to EN 1559 1 [3] and EN 1559 3 [4].
This document does not cover chemical composition, except phosphorus (see Clause 6).

Gießereiwesen - Temperguss

Dieses Dokument legt die Sorten für und die zugehörigen Anforderungen an Temperguss fest.
Dieses Dokument legt, basierend auf den an Probestücken (die Proben sind) gemessenen mecha¬nischen Eigenschaften, fünf Sorten von entkohlend geglühtem Temperguss und neun Sorten von nicht¬entkohlend geglühtem Temperguss fest.
Dieses Dokument legt Werte für die Brinellhärte fest, die nur bestimmt werden, wenn diese Werte vom Käufer verlangt werden.
Dieses Dokument enthält nicht die Technischen Lieferbedingungen für Temperguss. Es kann auf EN 1559 1 [3] und EN 1559 3 [4] Bezug genommen werden.
Dieses Dokument enthält keine Angaben über die chemische Zusammensetzung mit Ausnahme von Phosphor (siehe Abschnitt 6).

Overview

EN 1562:2019 - Founding - Malleable cast irons (CEN) defines grades and mechanical requirements for malleable cast irons used in foundry products. The standard classifies materials into whiteheart (decarburized) and blackheart (non-decarburized) malleable cast iron groups, specifying five whiteheart and nine blackheart grades. Mechanical properties are established from cast test samples; chemical composition is not covered except for phosphorus (see Clause 6). Brinell hardness is reported only when requested by the purchaser.

Key topics and requirements

• Material classification: Distinguishes whiteheart and blackheart malleable cast irons and their microstructural differences (temper carbon, ferrite/pearlite content).
• Grades and designation: Materials are designated by symbol or number (aligned with EN 1560/EN 10027–2 principles); properties relate to a preferred test-piece diameter (nominal 12 mm).
• Mechanical properties:
  • Tensile strength and elongation are mandatory and measured on cast samples.
  • 0.2% proof strength is included when requested by purchaser.
  • Brinell hardness values are determined only if specified in the order (guidance values appear in the standard’s tables).
  • Impact energy testing is normally required for specific grades (e.g., EN‑GJMB‑350‑10) and for grades used in pressure equipment; Charpy V-notched tests are used for pressure applications, while un‑notched Charpy may be used for other grades (Annex B).
• Sampling and test pieces: Defines cast sample types (separately cast and side‑by‑side), sizes, and wall‑thickness dependence of mechanical properties.
• Manufacture and composition: The manufacturer determines melt practice, composition and heat treatment to meet specified properties; phosphorus should be limited (≤ 0.10 %) for castings subject to additional treatments or low‑temperature service.
• Scope exclusions: Does not cover technical delivery conditions for castings - see EN 1559‑1 and EN 1559‑3 for delivery requirements.

Applications and users

• Foundries and casting manufacturers specifying or producing malleable cast iron components.
• Materials engineers, procurement specialists and quality inspectors who need standardized mechanical property requirements.
• Designers of components for general engineering and some pressure equipment (only permitted grades and conditions apply).
• Test laboratories performing tensile, Brinell and Charpy testing to verify compliance.

Related standards

• EN 1559‑1, EN 1559‑3 (technical delivery conditions for malleable cast iron castings)
• EN 1560 (designation system)
• EN ISO 6892‑1 (tensile testing), EN ISO 6506‑1 (Brinell), EN ISO 148‑1 (Charpy)
