Product Overview

The high manganese steel cone crusher bowl liner (also known as concave or fixed cone liner) is one of the most critical wear parts in cone crushing operations. As the stationary crushing surface, the bowl liner works in conjunction with the mantle (moving cone liner) to crush materials through compression, impact, and shear forces.

During operation, the cone crusher bowl liner withstands extremely intense, high‑frequency, and repeated alternating stresses, including impact, friction, compression, and shear. The quality and performance of the bowl liner directly determine the operational efficiency and productivity of the entire crushing system.

Material Excellence

Why High Manganese Steel?

High manganese steel is the industry-preferred material for cone crusher wear parts due to its exceptional work-hardening capability. Under high impact loads and compressive stresses, the surface layer of high manganese steel rapidly hardens from an initial hardness of HB180-220 to over HB500, creating an extremely wear-resistant surface layer while the inner austenitic structure maintains excellent impact toughness.

Our high manganese steel bowl liners are manufactured using premium-grade materials that meet international standards including ASTM A128, GB/T 5680, and equivalent specifications.

Available Material Grades

We offer a comprehensive range of high manganese steel and manganese-chromium alloy grades to suit different crushing applications:

Material Grade	Carbon (C) %	Manganese (Mn) %	Chromium (Cr) %	Silicon (Si) %	Hardness (HB)	Tensile Strength (MPa)
Mn13 (ZGMn13-3)	0.90–1.30	11.00–14.00	–	0.30–0.80	180–220	≥685
Mn13Cr2 (ZGMn13Cr2)	1.10–1.30	11.00–14.00	1.60–2.50	0.30–0.60	180–220	≥685
Mn18 (ZGMn18)	1.10–1.40	17.00–20.00	–	≤0.80	190–240	≥685
Mn18Cr2 (ZGMn18Cr2)	1.10–1.40	17.00–20.00	1.60–2.50	0.30–0.60	190–240	≥685
Mn22Cr2 (ZGMn22Cr2)	1.10–1.40	20.00–24.00	1.60–2.50	0.30–0.60	190–240	≥685

Material Characteristics by Grade

Mn13 (ZGMn13-3) – The standard high manganese steel grade with high tensile strength, excellent plasticity and toughness, and non-magnetic properties. Even when worn to very thin sections, Mn13 bowl liners can withstand significant impact loads without fracture.
Mn13Cr2 – By reducing carbon and manganese content while adding chromium, this grade compensates for the toughness limitations of traditional high manganese steel and significantly extends the service life of wear parts.
Mn18 – With higher manganese and carbon content, Mn18 offers superior work-hardening characteristics. After water toughening treatment at 1050°C, most carbides dissolve into the austenitic structure, providing excellent impact resistance.
Mn18Cr2 – The chromium-alloyed ultra-high manganese steel grade delivers superior wear resistance and longer service life in high-abrasion applications. As the surface hardening layer gradually wears away, new work-hardened layers continuously form.
Mn22Cr2 – The highest manganese content grade offering the most aggressive work-hardening rate and highest initial hardness, ideal for the most demanding high-stress crushing environments.

Advanced Casting & Heat Treatment Process

01.

Precision Casting Technologies

Our cone crusher bowl liners are produced using state-of-the-art casting processes to ensure superior quality and consistency:

V-method casting – Produces bowl liners with excellent surface finish and dimensional accuracy
Lost foam casting – Enables complex geometries with minimal defects
Water glass sand casting – Delivers high-quality castings with fine surface quality and internal integrity

We utilize numerical simulation technology to optimize casting process parameters, minimize casting stress, and ensure uniform wall thickness with dense internal structure free from shrinkage, cracks, and other defects.

02.

Water Toughening Heat Treatment

All high manganese steel bowl liners undergo rigorous water toughening (solution treatment) at 1000–1100°C. This critical heat treatment process:

Dissolves carbides into the austenitic matrix
Eliminates the as-cast structure
Creates a uniform single-phase austenitic structure
Maximizes impact toughness and work-hardening capacity

Our automated heat treatment system ensures precise temperature control and rapid quenching (within 35 seconds of heat treatment completion), resulting in superior metallographic structure and up to 20% longer service life compared to standard manganese steel liners.

Comprehensive Customization Services

We understand that every crushing operation has unique requirements. Our full-service customization capability ensures you receive the perfect bowl liner for your specific application.

What We Can Customize

Material Composition – Choose from our standard grades or provide your own chemical composition specifications. We can tailor the alloy content to match your specific rock properties and crushing conditions.
Dimensions & Geometry – We support custom sizing, thickness, and profiles based on your equipment model and crushing requirements. Whether you need a standard coarse crushing chamber, a fine chamber, or an extra‑fine chamber configuration, we can manufacture accordingly.
Cavity Design – Our technical team can optimize the curvature and tooth profile of the bowl liner to improve crushing uniformity, increase throughput, and reduce uneven wear.
Composite Materials – For extreme applications, we offer dual‑metal composite bowl liners that combine a high manganese steel base with cemented carbide or ceramic particles embedded in the working zone. This innovative design provides:

Excellent wear resistance on the working surface
Superior plasticity and impact toughness on the non‑working surface
Significantly extended service life
