The atomic structure explains why austenitic materials are generally soft and ductile and with the correct chemistry will work harden to perform a number of applications. Austenitic manganese steel has outperformed any other material for crusher wear liners for over 100 years.
The ?standard Hadfield austenitic manganese steel described in Australian Standard AS2074 Grade H1A remains the most ?reliable ?material for crusher wear liners.
The present study aims to evaluate the abrasion wear of two austenitic manganese steels with different concentration of manganese submitted in the jaw crusher test. The subsurface's microstructure and micromechanism were analysed as well by different microscopy techniques.
Manganese steel wear liners. Why manganese? Manganese steel has been used in crushing applications for over 100 years, so it's easy to take it for granted. It continues to …
High-manganese (Mn) cast steels (HMS) exhibit high toughness, wear resistance, high work-hardenability and have a relatively low cost of production, which makes them suitable for rock crushing and sizing operations. Although high-Mn steels have limited high temperature applicability, they have been used in clinker crusher operations …

Austenitic manganese steel is used in equipment for handling and processing earthen materials (such as rock crushers, grinding mills, gredge buckets, power shovel buckets …
High manganese steel typically contains around 11% to 15% manganese, which is significantly higher than traditional steel. The high manganese content creates austenitic crystals during solidification, resulting in work-hardening ability – a unique characteristic of this material. Additionally, the presence of carbon further enhances the …
In hardening and martempering conditions austenitic manganese steel was free from carbides both at the grain boundaries and in the grains. Hence, the crusher jaws produced with austenitic manganese in these conditions eradicated brittle failure experienced in locally produced crusher jaws.
The examined isothermally annealed steel is composed of four microstructural components: an austenitic matrix, (Fe,Mn) 3 C carbide in the form of a continuous network along the grain boundaries of the former austenite, (Fe,Mn) 3 C carbide in the form of needle-like precipitations, and fine pearlite colonies.
It is well established that austenitic manganese steel has a superior work-hardening ability but an inferior weldability [4–7]. Austenitic manganese steel is sensitive to reheating at temperatures ranging from 250 °C to 850 °C due to rapid carbide precipitation [8, 9].

This study focussed on the work hardening behaviour and microstructure of austenitic manganese steel relative to premature failure of crusher jaws. Samples of sound and failed crusher jaws were taken, the change with depth from the working surface to the sample core was measured and their microstructures observed.
High manganese steel (Hadfield) or Austenitic manganese steel is used in high impact application due to ability to work harden from impact loading. it is used to produce machine spare parts such as Cone crusher, Gyratory crusher, Jaw crusher, Hammer mill for heavy industries.

Hadfield steel also known as Hadfield steel or Hadfield austenitic manganese steel was invented by Sir Robert Hadfield in 1882. The first British patent for this steel, number 200 was granted for this steel in 1883. The first US patents, numbers 303150 and 303151, were granted in 1884. Fig 1 shows the commemorative plaque of Sir …
The secondary cone crusher's shields at Sarcheshmeh Copper Complex of Iran are made of Hadfield steel with a nominal composition of Fe-1.3 % C-12 % Mn. They have a cut-off in the shape of a cone with…

This is highly significant in that Austenitic Manganese steel has the property of rapid work hardening, which is why it finds application in wear resistant and impact environments, such as cone, gyratory, jaw and impact crusher wear parts, as well as linings for semi-autogenous mills and shoes for draglines etc.
An investigation into the work-hardening mechanism and the method of improving the work-hardening ability and the wear resistance of austenitic manganese steel, under non-severe impact-loading conditions, by means of transmission electron microscopy and X-ray diffraction has been conducted in this project. The results indicate …
