Overview
ISO 13521:2023 - Austenitic manganese steel castings - is an international standard that specifies austenitic manganese cast steels intended for wear‑resistant service where surfaces are subject to impact. This third edition (2023) is a minor revision of the 2015 edition and sets delivery, heat‑treatment, chemical, mechanical test and microstructure requirements to maximize service life of impact‑loaded cast components.
Key topics and technical requirements
- Scope and delivery: Applies to a range of austenitic manganese steel grades for impact wear applications. Materials furnished under this standard shall also conform to the general delivery requirements of ISO 4990.
- Heat treatment: Solution heat‑treat at temperatures not lower than 1 040 °C, followed by quenching in water. Exception: GX90MnMo14 may be supplied without heat treatment when casting thickness is < 45 mm and carbon content < 0.8 %.
- Chemical composition: The standard defines elemental limits (C, Si, Mn, P, S, Cr, Mo, Ni) for multiple grade designations (examples include GX120MnMo7–1, GX110MnMo13–1, GX120MnCr13–2, GX120MnNi13–3, GX120Mn18, etc.). Some grades are noted as occasionally used for non‑magnetic service.
- Mechanical testing:
- Bend test per ISO 7438 - specimens agreed between purchaser and manufacturer; must withstand bending at room temperature (18–28 °C) through 150° without breaking into two or more pieces (surface cracks are acceptable if the specimen remains intact).
- Hardness test per ISO 6506 - hardness shall be a maximum of 300 HBW, unless otherwise agreed. Hardness control is recommended when machining is required.
- Microstructure: Metallographic examination is performed when agreed; standard microstructure charts can be specified between parties.
- Supplementary requirements: A list is available in ISO 4990; others may be added by agreement.
Applications and users
ISO 13521 is used by:
- Foundries producing wear‑resistant castings (crusher jaws, liners, impact plates and similar components)
- Materials and metallurgical engineers specifying manganese austenitic steels
- OEMs and end‑users in mining, quarrying, aggregate processing, and heavy earthmoving where surfaces experience repeated impact
- Procurement, quality assurance and inspection teams ensuring conformance to chemical, heat‑treatment and test requirements

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
