Mn13Cr2 high manganese steel casting hammers

Mn13Cr2 high manganese steel casting hammers are engineered for extreme durability and wear resistance in heavy-duty industrial applications. These hammers are widely used in mining, cement production, and construction due to their exceptional impact toughness and work-hardening properties under dynamic loads.

    Material & Properties

    Mn13Cr2 Steel Is A Modified High Manganese Alloy With Added Chromium For Enhanced Hardness And Corrosion Resistance. The chemical composition includes carbon (C: 0.9-1.4%), manganese (Mn: 11-14%), chromium (Cr: 1.5-2.5%), as well as silicon (Si: 0.3-0.8%), sulfur (S), and phosphorus (P), etc.

    Property Description
    Material Grade Mn13Cr2 (ASTM A128)
    Hardness (HB) 200-300 (Unhardened), Up to 450 (Work-Hardened)
    Impact Toughness (J/cm²) ≥120
    Tensile Strength ≥800 MPa
    Work Hardening Increases hardness under impact
    Corrosion Resistance Improved vs. standard Mn13 due to chromium content

    Mn13Cr2 hammers are ideal for: 

    ✅ Mining Industry: Crusher hammers for limestone, granite, and ore processing.
    ✅ Cement Plants: Used in clinker breakers and crushers.
    ✅ Recycling: Shredder hammers for metal and waste processing.
    ✅ Construction: Breaker tools in demolition work. 
    Performance advantage: Longer service life (3-5x vs. standard carbon steel hammers) due to work-hardening effect. 

    Why Choose Our Mn13Cr2 Casting Hammer?

    1. Advanced

      *  High Manganese Content (11-14%): Enhances toughness and work-hardening capability.

      *  Optimized Design: Precision casting ensures uniform grain structure for consistent performance. 

      *  Custom Solutions: Available in multiple sizes (weight: 5-150 kg) and mounting configurations. 

      *  Certified Quality:  ISO 9001 compliant with strict metallurgical testing. 

      *  Bulk Order Programs: Discount pricing for truckload quantities (50+ hammers). 


    2. Performance

      *  Work-Hardening Effect - The hammer surface hardens under repeated impact, increasing wear resistance over time.  

      *  Optimized Weight Distribution - Precision-cast for smooth operation & reduced vibration in crushers.   

      *  Non-Destructive Testing (NDT) - Ultrasonic & magnetic particle inspection ensures defect-free castings. 


    3. Industry Applications

      *  Mining: Crushing copper, gold, and iron ore in ball mill & jaw crusher systems.

      *  Cement Plants: High-volume limestone processing (1000+ tons/day). 

      *  Recycling: Shredding concrete, asphalt, and demolition waste (30% longer life vs. standard hammers). 

    Industry-Recognized, Real-World Performance

    ✅ Case Study: A copper mine in Chile replaced standard hammers with our Mn18Cr2 model, increasing service life from 6 to 18 months and reducing replacement costs by 40%.

    ✅ Verified Compliance: All hammers meet ASTM A128, DIN 1.3401, and GB/T 5680 standards.

    ✅ Global Supply Chain: Fast shipping from US, EU & Asia warehouses (15–30 days lead time).

    PRODUCTION FOLW CONTROLCONTROL

    control 1_1

    Raw Material Quality Control

    1. Strictly monitor the chemical composition, purity, and impurity levels of metal materials (e.g., pig iron, scrap steel, alloys).
    2. Conduct performance tests (e.g., permeability, strength) on auxiliary materials such as casting sand and binders.
    control 2_1

    Melting Process Control

    1. Precisely control melting temperature (avoid overheating or insufficient heating).
    2. Ensure compositional uniformity with rapid chemical analysis before pouring.
    3. Perform deoxidation and degassing (vacuum melting for critical castings).
    control 3_1

    Mold/Core Quality Control

    1. Mold dimensional accuracy must meet drawing requirements (focus on parting surfaces, draft angles, etc.).
    2. Sand compactness, moisture content, and permeability must comply with process standards.
    3. Monitor curing levels for special processes like resin sand and lost foam casting.
    control 4_1

    Gating System Design Control

    1. Scientifically design gating systems (sprue, runner, and ingate ratios).
    2. Control pouring temperature (typically 50-150°C above the liquidus line).
    3. Use appropriate pouring speeds to avoid turbulence-induced gas entrapment.
    control 5_1

    Solidification Process Control

    1. Implement directional solidification techniques (e.g., mold temperature control, chill placement).
    2. Apply progressive solidification for critical components.
    3. Monitor cooling curves against expected profiles.
    control 6_1

    Post-Processing Control

    1. Strictly manage timing and methods for sand removal and riser cutting.
    2. Standardize heat treatment (annealing/normalizing/quenching with parameter logs).
    3. Control aging treatment time and temperature.
    control 7_1

    Dimensional & Defect Inspection

    1. Full-scale dimensional inspection (100% verification of critical dimensions).
    2. Apply non-destructive testing (X-ray, ultrasonic, magnetic particle inspection, etc.).
    3. Sample tests for microstructure and mechanical properties.
    control 8_1

    Traceability Management

    1. Maintain comprehensive records per batch (heat number, operators, timestamps, etc.).
    2. Archive process inspection data and visual documentation.
    3. Establish a complete quality file system.
