The reliability of crusher wear-resistant parts largely depends on the metal materials they adopt. Different metal materials have unique mechanical properties, which determine their adaptability to various crushing environments. This article classifies common metal - based wear - resistant materials for crushers, analyzes their core advantages and applicable scenarios, helping you select the most suitable materials for your crusher components.
Core Performance Comparison of Metal - Based Wear - Resistant Materials
Metal Material Type | Carbon Content | Hardness (HRC) | Toughness | Key Advantages | Ideal Crusher Parts |
Manganese Steel | 0.9 - 1.2% | 20 - 30 (work - hardens to 45+) | Excellent | Work - hardening, impact resistance | Jaw plates, blow bars, rotor tips |
High - Chrome Cast Iron | 2.5 - 3.5% | 60 - 65 | Moderate | Superior abrasive wear resistance, cost - effective | Low - impact wear liners, cone mantles |
Abrasion - Resistant Alloy Steel | 0.3 - 0.6% | 40 - 50 | Good | Balanced hardness and toughness, corrosion resistance | Cone crusher liners, impact plates |
Nickel - Hard Cast Iron | 2.8 - 3.2% | 58 - 63 | Moderate - Low | High hardness, good dimensional stability | Chutes, non - impact wear components |
Key Features & Application Scenarios of Each Material
- Manganese Steel: It is the classic choice for high - impact crushing scenarios. When impacted by rocks and ores, its surface will quickly harden while the internal structure remains tough, effectively preventing cracking and deformation. It is widely used in impact crushers and jaw crushers that handle hard materials such as granite and basalt.
- High - Chrome Cast Iron: Its ultra - high hardness comes from the chromium carbide in its structure, making it a star material for resisting abrasive wear. However, due to its poor toughness, it is only suitable for low - impact equipment parts, such as wear liners of slow - speed roll crushers.
- Abrasion - Resistant Alloy Steel: By adding elements such as chromium and molybdenum, it achieves a perfect balance between hardness and toughness. It not only resists daily friction and wear but also can withstand occasional impact loads, making it suitable for complex working conditions such as wet - type crushing.
- Nickel - Hard Cast Iron: Compared with ordinary cast iron, the addition of nickel significantly improves its hardness and wear resistance. It has good dimensional stability and is not easy to deform during long - term use, making it an ideal choice for fixed - position wear parts such as chutes and feed ports.
