Impact Crusher Blow Bar Materials
Manganese Steel Blow Bars (Mn18Cr2 & TiC Reinforced)
Mn18Cr2 manganese steel blow bars are ideal for high-impact crushing applications, especially where large feed materials or tramp metal may enter the crusher. The material work-hardens during operation, combining a tough core with increasing surface hardness.
Upgrade Option: TiC Reinforced Blow Bars
TiC inserts provide localized hardness up to 3200 HV along the wear surface, significantly improving edge wear resistance while maintaining the impact strength of manganese steel.
High Chrome Blow Bars (High Chromium & Ceramic Inserts)
Mn18Cr2 manganese steel blow bars are designed for high-impact crushing, especially where large feed or tramp metal may enter the crusher. The material work-hardens during operation, combining a tough core with increasing surface hardness.For more abrasive conditions, TiC reinforced blow bars extend service life while maintaining high impact strength.
Upgrade Option: High Chrome + Ceramic Insert
Ceramic inserts significantly improve wear resistance, delivering 2–3× longer service life compared to standard high chrome blow bars. Ideal for highly abrasive applications such as manufactured sand, asphalt recycling and fine crushing.
Martensitic Steel Blow Bars (Martensitic & Ceramic Reinforced)
Martensitic steel blow bars balance impact and wear resistance for crushing applications. With hardness of 48–54 HRC, they offer higher wear resistance than manganese steel and better toughness than high chrome. They perform well in moderate-impact and abrasive conditions. Ceramic reinforced options extend wear life while maintaining impact strength.
Upgrade Option: Ceramic Reinforced Blow Bars
Ceramic inserts improve wear resistance and extend service life while maintaining good impact strength. Ideal for applications combining impact and abrasion.
How to Choose Blow Bar Material by Application
Choosing the right impact crusher blow bar material depends on impact level, feed size and abrasiveness. Use the guide below to quickly match materials to your crushing conditions.
| Application Condition | Recommended Material | Why Choose It ? |
|---|---|---|
| High impact, large feed, tramp metal | Mn18Cr2 Manganese | Maximum impact resistance with work-hardening capability |
| High impact + high abrasion | Mn18Cr2 + TiC | Improved wear resistance while maintaining high impact strength |
| Moderate impact, mixed materials | Martensitic Steel | Balanced wear resistance and impact toughness |
| Abrasive + some impact | Martensitic + Ceramic | Extended wear life with stable performance |
| Low impact, high abrasion (clean feed) | High Chrome | Maximum wear resistance for consistent materials |
| Ultra-abrasive, controlled feed | High Chrome + Ceramic | Extended service life in extreme wear conditions |

Blow Bar Rotation & Maintenance Tips
Proper blow bar rotation and maintenance are essential for maintaining rotor balance and maximizing wear life. Follow these basic guidelines to improve performance and prevent unexpected failures.
Wear Management
25–30%
worn
Rotate 180°
Rotate blow bars 180° (flip end-to-end) to expose a new wear surface and extend service life.
50–60%
worn
Move Position
Move blow bars from leading to trailing position to reduce impact load and balance wear.
70–80%
worn
Replace Blow Bars
Replace blow bars to prevent rotor imbalance and excessive vibration.
Installation
Blow Bar Weight Difference
Keep the weight difference between opposite blow bars minimal to maintain proper rotor balance.
Rotor Balance
Ensure proper rotor balance during installation to reduce vibration and minimize bearing wear.
Ceramic / TiC Blow Bars
Use stricter balance control. Inserts are more sensitive to imbalance.
Inspection
Routine Inspection
Check regularly for cracks or excessive wear to prevent unexpected equipment failures.
Before Rotation
Do not reuse cracked blow bars. Also inspect mounting holes and fasteners for wear or elongation.
Mounting Check
Check mounting holes and fasteners for wear or elongation.
Before Rotation – Important Check
⚠ Inspect blow bars for cracks before rotation or flipping
⚠ Do not reuse cracked blow bars to avoid unexpected failure
⚠ Check mounting holes and fasteners for wear or elongation

Blow Bar FAQs
Find answers to common questions about impact crusher blow bars, materials, wear life, and replacement.
Which blow bar material lasts the longest?
The longest-lasting blow bar material depends on the application. For highly abrasive conditions, high chrome and ceramic reinforced blow bars provide the best wear life. For high-impact applications, manganese steel offers longer service life due to its work-hardening properties.
Can high chrome blow bars be used in recycling applications?
Yes, high chrome blow bars are widely used in recycling applications such as concrete and asphalt crushing. However, if tramp metal or large feed materials are present, manganese steel or martensitic blow bars are recommended for better impact resistance.
Do ceramic blow bars break easily?
Ceramic reinforced blow bars do not break easily when used in the correct conditions. They offer superior wear resistance for abrasive materials, but are not recommended for primary crushing or applications with heavy impact or tramp metal.
How often should impact crusher blow bars be replaced?
Blow bar replacement intervals depend on material type, feed size and operating conditions. In most applications, blow bars are rotated several times before replacement, and regular inspection is essential to prevent excessive wear and rotor damage.
What information is required to quote blow bars?
To provide an accurate quotation, please supply the crusher brand and model, blow bar part number or dimensions, material preference and application details. Drawings or photos are recommended to ensure correct fit and optimal performance.
