Excavator bucket tooth material analysis: comparison of the advantages and disadvantages of various materials
In the field of engineering machinery, excavator bucket teeth are vulnerable parts that are in direct contact with materials, and their material selection directly affects operating efficiency and operating costs. The mainstream bucket tooth materials on the market mainly include three categories: high manganese steel, alloy steel, and tungsten carbide coating. This article will analyze the differences in the characteristics of these three materials from a professional perspective, and focus on how Yuezhong Machinery improves bucket tooth performance through innovative material processes.
1. High manganese steel bucket teeth: a classic choice
Material characteristics: High manganese steel (Mn13 series) is the traditional material for bucket teeth, with the main components: carbon (C): 0.9%-1.3%, manganese (Mn): 11%-14%, silicon (Si): 0.3%-0.8%, phosphorus/sulfur (P/S): ≤0.05%
Advantage analysis: Work hardening characteristics: The surface hardness can be increased from HB200 to above HB500 under impact load
Impact toughness: Elongation can reach 35%-55%
Economical efficiency: The cost of raw materials is about 25% lower than that of alloy steel
Limitations: Insufficient hardening effect under low stress conditions, and wear resistance is lower than that of high-end alloy materials
Yuezhong optimization solution: The YC-Mn14 series displayed on Yuezhong's official website adopts: Mn-Cr composite addition technology (Mn13Cr2), multi-stage water toughening treatment process, grain size control at level 5-7, and product life is increased
2. Alloy steel bucket teeth: a balanced choice
Material characteristics: Typical composition: Carbon (C): 0.3%-0.5%, Chromium (Cr): 1.5%-3%, Molybdenum (Mo): 0.2%-0.5%, Boron (B): 0.001%-0.005%
Advantage analysis: Stable hardness: HRC55-60 after heat treatment, good comprehensive performance: tensile strength ≥1500MPa, wide adaptability: suitable for medium and high stress conditions
Limitations: Toughness is lower than high manganese steel (impact energy is about 25J), welding repair is difficult, and the price is 30%-40% higher than high manganese steel.
Yuezhong innovative process: The YC-Alloy series displayed on the website adopts: vacuum degassing smelting technology, isothermal quenching process, nano-surface treatment, and achieves hardness HRC58-6 2. Maintain impact energy of more than 35J at the same time
3. Tungsten carbide coated bucket teeth: high-end choice
Material characteristics: substrate + surface treatment: substrate: alloy steel/high manganese steel, coating: WC content 85%-93%, thickness: 0.3-1.2mm
Advantage analysis: Extreme wear resistance: hardness above HRA90, applicable to special working conditions: highly abrasive materials, life doubled: up to 2-3 times that of ordinary bucket teeth
Limitations: brittle, poor impact resistance, complex process, expensive, cannot be repaired and reused
Yuezhong Technology Breakthrough: YC-WC series innovations highlighted on the official website: gradient transition layer technology, supersonic flame spraying (HVOF) process, three-dimensional profiling coating design: make the coating bonding strength reach more than 80MPa
