HighCr Durable and High-Performance Wear Parts
Blow Bars for Impact Crushers
Highcr delivers the precise blow bar solution you need to dominate your crushing applications. We understand that no single alloy fits all conditions. That’s why we offer a comprehensive portfolio of six proprietary materials—from traditional Manganese to cutting-edge Ceramic and Carbide Composites—engineered to provide superior fracture resistance, reduced wear rates, and minimized downtime.
By precisely matching one of our six specialized alloys to your specific feedstock (limestone, asphalt, recycling, etc.) and crushing volume, Highcr guarantees a lower Cost-Per-Ton (CPT) and a longer service life than conventional OEM parts.
6 Specialized Blow Bar Alloys: Find Your Perfect Match
Choose the optimal Highcr material that aligns with your specific impact and abrasion requirements:
1. Standard Solutions for Impact & Toughness
| Material | Description & Core Benefit | Ideal Application |
| Manganese Steel (Standard) | Our High Manganese Steel (e.g., Mn18Cr2, Mn22Cr2) is the industry standard for high-impact applications. Its core benefit is work-hardening—the surface hardens rapidly upon impact, extending durability while the core remains tough and fracture-resistant. | Primary crushing of hard, tough rock like granite and basalt, or high-volume demolition concrete. |
| Martensitic / Low Chrome Steel | This alloy provides an excellent balance between toughness and abrasion resistance. It offers higher hardness than standard Manganese steel, making it ideal for medium-impact conditions where improved wear life is desired. | Medium-impact applications, mixed material crushing, and areas requiring less work-hardening. |
2. High-Abrasion & High-Hardness Solutions
| Material | Description & Core Benefit | Ideal Application |
| Chrome White Iron | The best choice for pure abrasion resistance. Rich in Chromium Carbides, this material is extremely hard (typically 58-65 HRC) and excels where grinding and rubbing wear are the primary concern. | Crushing hard silica/quartz or heavily abrasive aggregates, secondary and tertiary crushing stages. |
| Manganese Steel with Titanium Carbides (TiC) Inserts | An innovative composite solution. High-toughness Manganese steel acts as the matrix, housing ultra-hard TiC inserts strategically placed in high-wear zones. This combination offers both high impact resistance and localized extreme wear life. | Harsh mining applications requiring both toughness and maximum wear life; high impact and medium abrasion. |
3. Premium Composite Solutions for Extreme Service Life (MMC)
| Material | Description & Core Benefit | Ideal Application |
| Chrome with Ceramic | A superior Metal Matrix Composite (MMC). High Chrome White Iron is embedded with ceramic inserts, drastically slowing wear, while the chrome matrix manages the surrounding abrasion. | High-abrasion environments demanding the absolute longest lifespan, such as high-silica materials or recycling asphalt. |
| Martensitic / Low Chrome with Ceramic | Combining a tougher Martensitic matrix with ceramic inserts. This alloy is the best choice for conditions with a moderate level of impact and significant abrasion. The Martensitic body resists breakage, and the ceramics fight wear. | Crushing mixed materials (e.g., C&D waste, concrete with rebar), or applications where standard ceramic blow bars are prone to fracturing. |
Ceramic Blow Bar
Highcr Ceramic Inserted Blow Bars represent the pinnacle of wear-part engineering. Designed specifically for crushing materials characterized by severe abrasion and fine particulates (such as high-silica rock, glass, or recycled concrete), these bars utilize Metal Matrix Composite (MMC) technology.
We strategically embed high-hardness ceramic inserts into a tough metallic matrix (typically High Chrome White Iron or Martensitic Steel). This creates a dual-action bar: the ceramic inserts provide localized, while the matrix protects the inserts and handles moderate impact.
Performance Guarantee: Achieve the lowest Cost-Per-Ton (CPT) ratio by dramatically reducing the frequency of bar replacement and associated machine downtime.
TIC Blow Bar
Highcr Titanium Carbide (TiC) Inserted Blow Bars are the engineered upgrade for conditions that require the toughness of Manganese steel but suffer from rapid wear. By embedding TiC inserts—a material renowned for its high hardness and chemical stability—into a Manganese or Alloy steel matrix, we create a bar that simultaneously offers:
-
High-Impact Resistance: The steel matrix retains its ductility and work-hardening capability, preventing fracture.
-
Exceptional Wear Life: The TiC inserts act as robust wear barriers, significantly extending the bar’s service life, especially under high-stress abrasion.
Process Advantage: Our unique casting process ensures a permanent, metallurgical bond between the TiC inserts and the steel matrix, eliminating separation or shedding under heavy impact.
Highcr Manufacturing & Technical Advantage
Our commitment to quality extends from the furnace to final fitment.
-
Precision Casting & Fitment: Using advanced Modified Water Glass and Lost Wax casting techniques, we achieve the precise dimensional accuracy required for perfect fit and balanced rotor operation, minimizing installation time and reducing harmful machine vibration.
