As a leading manufacturer with a decade of experience in the crushing machinery sector, Henan San Kuang Machinery Technology Co., Ltd. proudly presents our premium Crusher Hammer Made from Mn13Cr2 Alloy Steel. Engineered specifically for the demanding environments of aggregate processing, this hammer represents the culmination of our expertise, advanced manufacturing capabilities within our expansive 10,000-30,000 square meter facility, and commitment to delivering wear parts that significantly reduce operational downtime and total cost of ownership. Our hammers are not just components; they are productivity investments designed to withstand the relentless impact and abrasion encountered in crushing limestone, granite, gravel, and other aggregates.
Our crusher hammers are distinguished by their superior material science and precision engineering. The core of their performance lies in the specialized Mn13Cr2 alloy steel, a high manganese grade enhanced with chromium. This material formulation offers a unique combination of high toughness and exceptional work-hardening capability. Upon repeated impact during service, the hammer's surface hardens progressively, forming a durable wear-resistant layer while maintaining a tough, shock-absorbing core. This dynamic property translates directly into a longer service life compared to conventional manganese steel hammers, leading to fewer change-outs, lower spare parts inventory costs, and increased crusher availability.
We employ state-of-the-art V-Process or EPC casting technology combined with precise heat treatment to ensure optimal metallurgical structure throughout the hammer. This process minimizes casting defects, ensures dimensional accuracy, and unlocks the full potential of the Mn13Cr2 material. Every hammer is machined to exact specifications for perfect fit and balance within your crusher, preventing vibration and premature failure of other components.
Key Technical Specifications & Advantages:
- Material Composition: Premium Mn13Cr2 High Manganese Alloy Steel. The addition of Chromium (Cr2) significantly improves yield strength, hardness penetration, and overall wear resistance.
- Superior Wear Life: Can offer a service life 1.5 to 2 times longer than standard Mn13 hammers in comparable aggregate processing applications, depending on feed material and operating conditions.
- Impact Resistance: Exceptional toughness absorbs high-impact forces without fracturing, making it ideal for processing large and hard rock.
- Work-Hardening Property: Surface hardness can increase from an initial HB 200-250 to over HB 500 during operation, creating a self-renewing wear-resistant surface.
- Customizable Design: We can manufacture hammers to fit a wide range of crusher models from major OEMs. Custom dimensions, weight profiles, and even hardfacing patterns are available upon request to optimize performance for your specific plant layout and material.
- Precision Manufacturing: Advanced casting and machining ensure precise balance, reducing dynamic loads on crusher rotors and bearings, thereby extending the life of your entire crushing system.

Frequently Asked Questions (FAQ):
-
Q: How does Mn13Cr2 compare to standard Mn13 or Mn18 material for hammers?
A: Mn13Cr2 offers improved performance. The chromium addition enhances hardenability and wear resistance, often providing a longer service life in high-abrasion aggregate applications compared to standard Mn13, while maintaining similar high toughness. It can be a cost-effective alternative to higher manganese grades like Mn18 in many scenarios. -
Q: Are these hammers suitable for very hard or highly abrasive rock like quartzite?
A: While Mn13Cr2 offers excellent wear resistance, for extremely abrasive materials, alternative solutions like martensitic steel hammers with ceramic inserts or specialized high-chromium iron might be recommended. We advise sharing your specific feed material analysis for a tailored recommendation. -
Q: Can you manufacture hammers for my specific crusher brand and model?
A: Absolutely. We specialize in customization. Please provide the OEM crusher model number, drawings, or a sample hammer, and we can produce an exact or improved replacement. -
Q: What is the typical lead time for an order?
A: Lead time depends on order quantity and customization complexity. For standard models, it typically ranges from 25 to 40 days. We provide accurate timelines upon order confirmation. -
Q: Do you offer any testing or quality certificates with the shipment?
A: Yes, we can provide material chemical analysis reports and hardness test reports. Other specific certificates are available upon request. -
Q: How should I store these hammers before installation to prevent damage?
A: Store them in a dry, covered area. Avoid stacking them in a way that causes point loading or impact on the working surfaces. Using wooden blocks for separation is recommended. -
Q: What packaging do you use for export shipments?
A: We use robust export-standard packaging, typically wooden crates or pallets with waterproof wrapping, to ensure the hammers arrive in perfect condition. -
Q: Can you provide guidance on the correct installation and maintenance to maximize hammer life?
A: Yes, we provide installation manuals and can offer operational advice, such as ensuring proper rotor balance, correct hammer positioning, and monitoring for uneven wear to schedule timely rotation or replacement.
