Core Materials and Characteristics

• The main material is high-standard alloy steel, and some are based on high manganese steel with added alloys to optimize performance.
• The production processes include forging, investment casting, sand casting, etc., to ensure structural strength.
• The key performance parameters are clear: hardness reaches 48-52HRC, tensile strength ≥1400N/mm², impact value ≥15J, with outstanding wear resistance and impact resistance.

  Applicable Operating Environment
• General engineering scenarios: routine operations such as earth excavation, river dredging, and construction foundation construction.
• Abrasion-resistant working conditions: high-wear environments such as quarries and mines for rock crushing and ore loading.
• Compatible equipment: 35-40 ton excavators, such as Hitachi ZX450, CAT, EC and other brand models, and can also be used for wheel loaders in quarries.

  Material Type	Core components	Production process	Key performance parameters	Applicable Environment Priority	Advantages and highlights	Notes
  High manganese steel reinforced	ZGMn13 + Chromium / Molybdenum Alloy	Sand casting + water toughness treatment	Hardness 45-48 HRC, impact value ≥25 J	Earthwork > Riverbed Dredging > Light Rock	High toughness, impact resistance, and not easy to break	The wear resistance is generally average, making it unsuitable for high-intensity mining operations.
  Low-alloy high-strength steel	42CrMo + vanadium / titanium micro-alloy	Forging + Tempering Treatment	Hardness 48-52 HRC, tensile strength ≥1400 N/mm²	Mixed operating conditions > Building foundation > Moderate quarrying	The comprehensive performance is well-balanced, combining wear resistance and impact resistance.	Moderate cost, suitable for routine heavy-duty operations
  High-chromium alloy wear-resistant steel	Cr12MoV + carbide strengthening	Investment Casting + Quenching and Tempering	Hardness 52-55HRC, wear-resistant layer thickness ≥8mm	Mining > Rock Crushing > High-Intensity Quarrying	It has excellent wear resistance and a long service life.	The toughness is slightly lower, so avoid severe impacts.
  Bimetallic composite material	High manganese steel matrix + high chromium alloy tooth tip	Composite Casting + Heat Treatment	Matrix hardness 45 HRC, tip hardness ≥58 HRC	Complex working conditions > Mixed quarrying + Earthwork	Balancing toughness and wear resistance with high cost-effectiveness	The production process is complex and requires choosing a reputable manufacturer.
