Impact crusher blow bars, also known as hammers, are essential components in horizontal shaft impact crushers. These thick alloy slabs are strategically inserted into the rotor, rapidly striking materials like asphalt, concrete, and natural stone. Their primary function is to fracture materials, ensuring efficient size reduction. Metallurgical variations, including low chrome, medium chrome, high chrome, and authentic blow bars are tailored for specific applications. Regular replacement is necessary as they wear out during the crushing process.
Market research shows that incorrect dimensions often result from sellers not confirming specifications with buyers. To prevent this, our seasoned engineers will double-check your part dimensions by verifying the drawing of your blow bars to ensure a 100% match with your impact crushers
We aim to help you make your hammers for impact crushers more wear-resistant based on keeping the original device accessories, extending their service life, reducing the replacement frequency, and lowering the operating costs, achieving a win-win cooperation. From non-wear-resistant applications to extreme wear scenarios, such as limestone, basalt, gneiss, or gravel with extremely high wear resistance requirements, whether it's limestone or dolomite, we have corresponding solutions.
Our drawing library covers more than 20 impact crusher brands, and before placing an order, our experienced engineers will double-check the dimensions of the impact plates.
Unlike the unstable supply sources of trading companies, our impact plates are self-produced and self-sold. We can guarantee that each batch of our impact plates is produced under high standards, and the production of each product can be traced back.
Our professional engineers will recommend the most suitable plate material based on the raw materials you need to crush, extend the service life, reduce the replacement frequency, and lower your operating costs.

When selecting blow bars, the primary criteria are hardness, toughness, and the material's performance under specific working conditions. These factors directly influence the wear resistance and impact resistance of the blow bars. Here are the key properties to focus on:
High chrome cast iron blow bars have high hardness and good wear resistance, making them suitable for materials with high abrasiveness but low impact force, such as granite, limestone, dolomite, calcite, sandstone, basalt, quartzite, corundum, bauxite, and iron ore.
Toughness is the material's ability to absorb energy and resist fracturing under impact. Higher toughness means better impact resistance.
Wear resistance is the material's ability to maintain integrity under abrasive conditions. High hardness usually translates to high wear resistance.
Impact resistance is the material's ability to resist fracturing under high-impact conditions. High toughness usually indicates high impact resistance.
Stellar Heavy's hammer metal material, including high manganese Steel (Mn13Cr2, Mn18Cr2, Mn22Cr2 or customized) and high chrome iron (KmTBCr20Mo, KmTBCr26 or customized)
High chrome cast iron blow bars have high hardness and good wear resistance, making them suitable for materials with high abrasiveness but low impact force, such as granite, limestone, dolomite, calcite, sandstone, basalt, quartzite, corundum, bauxite, and iron ore.
| Cr | C | Na | Cu | Mn | Si | Na | P | |
| KmTBCr26 | 23-30 | 2.3-3.3 | ≤2.5 | ≤2.0 | ≤1.0 | ≤1.2 | ≤2.5 | ≤0.16 |
With both high hardness and toughness, high manganese steel blow bars are suitable for materials with high impact force and severe wear, such as concrete, construction waste, scrap metal, hard rock, manganese ore, copper ore, lead-zinc ore, and nickel ore.
| Mn | Cr | C | Si | |
| Mn13Cr2 | 12-15 | 1.7-2.2 | 1.15-1.25 | 0.3-0.8 |
| Mn18Cr2 | 17-19 | 1.8-2.2 | 1.15-1.3 | 0.3-0.8 |
| Mn22Cr2 | 21-23 | 1.8-2.2 | 1.1-1.4 | 0.3-0.8 |
Depending on the material's wear resistance, select the highest grade KmTBCr26 or Mn22Cr2 blow bar to reduce the frequency of wear part replacements, ensuring durability and efficiency.
Wear resistance is a crucial factor in determining the suitability of blow bars for different materials. Higher wear resistance materials are suitable for crushing harder materials, while lower wear resistance materials are suitable for crushing softer materials.
By analyzing the wear resistance of both the blow bars and the materials, you can effectively improve crushing efficiency and extend equipment lifespan.
Below is a "Blow Bar Selection Guide" based on the theoretical wear resistance of high manganese steel (Mn13Cr2, Mn18Cr2, Mn22Cr2), high chrome cast iron (KmTBCr20Mo, KmTBCr26), and various common materials.
