How to choose between Mn13 and Mn18 manganese liners?

The choice depends primarily on the hardness of the ore and the impact intensity. Mn13 (Hadfield Steel) is the standard solution for low-to-medium abrasion materials and high-impact conditions, as it relies on impact to harden. Mn18 (including Mn18Cr2) contains higher chromium and carbon content, providing significantly better wear resistance for harder materials like granite, basalt, or iron ore. For extreme conditions, Mn22 is recommended to maximize service life.

Do you provide custom chemistry for specific mining conditions?

Yes. WALKSON specializes in customized alloy compositions tailored to your specific operational environment. Beyond standard Mn13 and Mn18, we can add elements like Molybdenum (Mo) to increase toughness and prevent brittle failure, or Nickel (Ni) and Copper (Cu) to enhance corrosion resistance in acidic (low pH) mining environments or high-humidity underground operations.

What is the average lead time for custom manganese casting?

Our typical lead time for custom manganese liners is 4 to 6 weeks. This includes pattern preparation, casting, heat treatment (water quenching), and quality inspection. For urgent B2B replacement projects, we offer optimized scheduling. Please provide your drawings or part numbers (for major crusher brands) for a precise quote and timeline.

Manganese Liners

Name: Manganese Liners
Brand: WALKSON

Crusher is the main equipment in crushing process of various kinds of ore and bulk material, which is widely used in mining, metallurgy, building materials, highway, railway, hydraulic engineering, and chemical industries.

Crusher parts can also be called crusher consumables, which are important parts of the crusher, such as Hammer Head, Jaw Plate, Mantle & Concave for crusher. For more information about different mill liners like SAG ball mill liner and wear resistant liner, please feel free to contact us.

Why Choose WALKSON Manganese Liners

Typical Manganese material are Mn13, Mn13Cr2, Mn18, Mn18Cr2, Mn22 etc. And we do accept customized chemistry as per your request.

High Manganese Steel Selection Guide: Materials & Technical Specifications

At WALKSON, we specialize in high manganese steel casting, also known as Hadfield Steel. Choosing the correct chemical composition is critical to balancing wear resistance and impact toughness. Our manganese liners are designed to undergo continuous work hardening, reaching a surface hardness of up to 500-600 HB under intense impact.

Technical Comparison Matrix

Material Grade	Hardness (Initial HB)	Impact Toughness (ak)	Optimal Application & Ore Type
Mn13 (Hadfield Steel)	180 - 220	≥ 150 J/cm²	Ideal for high-impact conditions with low-abrasion ores like limestone.
Mn13Cr2	200 - 240	≥ 120 J/cm²	The standard choice for secondary crushing and general mining environments.
Mn18Cr2	220 - 250	≥ 100 J/cm²	Recommended for hard rock (granite, basalt) and high-abrasion gold/copper mining.
Mn22Cr2	240 - 280	≥ 80 J/cm²	Designed for extreme crushing environments requiring the longest service life and maximum hardness.

Custom Alloy Solutions

Beyond standard grades, we offer custom chemistry modifications to meet specific site requirements:

Chromium (Cr) Addition: Increases initial hardness and improves wear resistance in abrasive conditions.

Molybdenum (Mo) Enhancement: Improves toughness and prevents brittle failure in cold climates or extreme impact zones.

The Power of Work Hardening: Why Choose High Manganese Steel?

Manganese steel, often called Hadfield steel, is the gold standard for high-impact environments. Unlike ordinary hardened steel, our manganese liners possess a unique ability to adapt to the working conditions of your crusher or mill.

The Science of Self-Hardening Service Life

The secret lies in its austenitic structure. When the liner surface is subjected to continuous heavy impact or high pressure, the molecular structure undergoes a transformation. This phenomenon, known as Work Hardening (or Strain Hardening), provides a dual-layer protection:

Hardened Surface Layer: Under impact, the surface hardness can rapidly increase from an initial 200 HB to over 500–600 HB. This creates a formidable barrier against abrasive ores and rocks.

Tough Internal Core: While the exterior becomes extremely hard to resist wear, the inner core remains relatively soft and ductile. This ensures the liner can absorb massive shocks without cracking or catastrophic failure—a common risk with high-chromium white irons.

Key Advantages of WALKSON Manganese Liners:

Dynamic Durability: The more your equipment works, the tougher the liners become.

Reduced Downtime: Exceptional toughness prevents premature cracking, leading to longer maintenance cycles.

Optimized Performance: Specifically designed for primary crushing of hard, tough materials like iron ore, copper ore, and granite.
