conjunction with these standards. Where no text is given under a clause heading, the corresponding clause
of EN 1559-1 or EN 1559-2 applies.
The structure of this standard is as follows:
a) clauses and subclauses preceded by Ø indicates no additional conditions to Part 1 or Part 2 1 )
of EN 1559;
b) subclauses without any marking are mandatory.

denen die Gussstückoberfläche schlagartiger Beanspruchung ausgesetzt ist.
Diese Europäische Norm behält für die Abschnitte den gleichen Aufbau bei wie EN 1559-1 und EN 1559-2.
Sie muss in Verbindung mit diesen Normen benutzt werden. Wenn unter einer Abschnittsüberschrift kein Text
steht, gilt der entsprechende Abschnitt von EN 1559-1 oder EN 1559-2.
Der Aufbau dieser Norm ist wie folgt:
a) Abschnitte und Unterabschnitte mit vorangestelltem Ø weisen darauf hin, dass es gegenüber EN 1559-1
oder EN 1559-21) keine zusätzlichen Bedingungen gibt;
b) Unterabschnitte ohne Kennzeichnung sind verbindlich.

Aciers moulés - Pièces moulées en acier austénitique au manganèse

La présente Norme européenne donne les spécifications relatives aux pièces moulées en acier austénitique
au manganèse résistantes à l’usure. Les nuances traitées dans la présente Norme européenne sont
destinées à une utilisation optimale dans des applications où la surface des pièces moulées est soumise aux
chocs.
La présente Norme européenne reprend les mêmes formats d’articles que l’EN 1559-1 et l’EN 1559-2. Il doit
être utilisé en conjonction avec ces deux normes. Dans le cas où aucun texte ne figure sous le titre de
l’alinéa, l’alinéa correspondant de l’EN 1559-1 ou de l’EN 1559-2 s’applique.
La structure de la présente norme est la suivante :
a) les articles et les paragraphes précédés par le symbole Ø n’indiquent aucune condition supplémentaire
par rapport à l’EN 1559-11) ou à l’EN 1559-21) ;
b) les alinéas sans aucun symbole représentent une exigence de la présente norme.

Jekleni ulitki - Ulitki iz avstenitnega manganovega jekla

Ta evropski standard opredeljuje lito avstenitno manganovo jeklo za protiobrabno storitev. Razredi, ki jih zajema ta evropski standard, bodo izkusili najdaljšo življenjsko dobo v opremah, kjer je površina odlitka podvržena udarcem. Ta evropski standard ohranja isto obliko zapisa za klavzule, kot sta EN 1559-1 in EN 1559-2. Uporablja se skupaj s temi standardi. Kjer pod naslovom klavzule ni podano nobeno besedilo, velja ustrezna klavzula EN 1559-1 ali EN 1559-2. Struktura tega standarda je, kot sledi: a) klavzule in podklavzule, pred tem pa ne navaja kakršnih koli dodatnih pogojev k delu 1 ali delu 2 1 ) iz EN 1559; b) podklavzule brez kakršnega koli označevanja so obvezne.

Overview

EN 10349:2009 - Steel castings - Austenitic manganese steel castings (CEN) defines the specification for austenitic manganese cast steels intended for wear‑resistant, impact‑subject applications. The standard is intended to be used together with EN 1559-1 and EN 1559-2, retaining their clause format and adding steel‑grade‑specific requirements (chemical composition, heat treatment options, mechanical testing and inspection rules).

Key topics and requirements

• Scope and purpose: Grades covered are optimized for maximum service life where surfaces are subject to impact and high wear.
• Grade designations and chemistry: The standard lists specific grades (for example GX120MnMo7-1, GX110MnMo13-1, GX100Mn13a, GX90MnMo14, GX120MnCr13-2, GX120MnNi13-3, GX120Mn18a, GX120MnCr18-2) with cast‑analysis chemical composition limits for C, Si, Mn, P, S, Cr, Mo, Ni.
• Heat treatment rules: Solution treatment and water quenching are required for many grades. Exception: GX90MnMo14 may be supplied without heat treatment when thickness < 45 mm and carbon < 0.8 %; for thickness ≥ 45 mm or C ≥ 0.8 % (and for other grades) solution treatment at ≥ 1 040 °C and water quench is required.
• Mechanical testing:
  • Bend test per EN ISO 7438: specimen must bend to 150° at room temperature (23 ± 5 °C) without breaking into two pieces; surface cracks that do not separate the piece are acceptable.
  • Brinell hardness per EN ISO 6506‑1: maximum hardness normally 300 HBW unless otherwise agreed; hardness testing may be required after heat treatment and before machining.
  • Microstructure and other tests may be performed when agreed between purchaser and manufacturer.
• Inspection & documentation: Inspection types, sampling, submission and acceptance conditions are covered. Place and timing of testing are agreed between purchaser and manufacturer.
• Supplementary provisions: Purchaser can invoke additional requirements from EN 1559 parts or agreed bespoke supplementary requirements.

Applications and practical value

EN 10349 is targeted at components exposed to severe impact and abrasion, such as:

• crusher liners, hammers and wear plates
• earthmoving and excavation parts
• mining and quarry equipment
• rail crossing and impact zones where austenitic manganese castings provide work‑hardening, high toughness and extended wear life

Using EN 10349 ensures material traceability, reproducible chemical and mechanical properties, and consistent acceptance/testing criteria for long‑life, wear‑resistant castings.

Related standards and users

• Related: EN 1559-1, EN 1559-2, EN ISO 6506-1, EN ISO 7438.
• Typical users: foundries, material engineers, specifiers, procurement teams, OEMs and end‑users in mining, aggregate processing, construction and heavy machinery industries.
