Cr26 High Chromium Alloy Crusher Hammers
Application: Mining, Cement, Construction Material, Metallurgy | Customization: Strict ±1mm Tolerance Based on Technical Drawings
As a leading heavy-duty crusher hammers manufacturer in China, Shandong Hengtai specializes in producing high-quality Cr26 high-chromium alloy casting components. This premium crushing part is engineered for demanding industries such as mining, cement plant raw material preparation, aggregate production, and metallurgy, primarily utilized to crush high-hardness ores and stones efficiently.
Our Cr26 alloy series are widely recognized as exceptionally tough crusher hammers. The core competitive advantage lies in their superior wear resistance and high impact toughness, which allows them to retain an extended service life in high-stress, high-wear working environments. By upgrading to our advanced wear parts, mining operators can significantly decrease unexpected machine downtime and substantially lower component replacement costs.

Manufacturing Excellence & Quality Control
Advanced Lost Foam Casting: Our foundry utilizes state-of-the-art precise casting methodologies (including lost foam casting and V-method casting) to form complex hammer geometries while maintaining lower production costs. Elements like Molybdenum (Mo) and Copper (Cu) are precisely added to refine grains and increase hardenability.
Rigorous Heat Treatment (Quenching + Tempering): Every batch undergoes sophisticated thermal treatment to obtain a uniform martensitic matrix. This ensures the optimal equilibrium between extreme surface hardness and internal structural impact toughness.
100% Non-Destructive Quality Inspections: To guarantee stable quality, we enforce strict QC: Spectrometry for chemical element analysis, Ultrasonic Testing (UT) to identify internal air holes or cracks, Rockwell Hardness Testers to verify heat treatment results, and digital calipers to ensure the strict ±1mm dimensional tolerance.

Frequently Asked Questions
The operational lifespan depends heavily on your material hardness. For medium-hardness materials like limestone, it lasts 6-12 months. For high-hardness rocks like iron ore, the replacement cycle is roughly 3-6 months. We recommend a replacement when the hammer wears down to 50%-60% of its original size to protect equipment safety.
Yes, absolutely. As a dedicated industrial wear parts supplier, we support full drawing customization. Customers can submit standard CAD files or physical samples, and our engineers will manufacture exact replacements matching the original parameters.
