Technical Specifications: Bucket Teeth

Material and heat-treatment options are selected against the confirmed application, target wear life, and required test documentation.

Material TypeIndustry StandardCharacteristics & Applications
High Manganese SteelZGMn13Classic material: Work-hardens rapidly under strong impact, vastly increasing wear resistance while maintaining high core toughness. Ideal for high-impact, rugged excavation.
Low Alloy Steel35CrMn, 42CrMoPremium aftermarket standard: Subjected to Quenching + Tempering heat treatment, providing excellent overall mechanical properties.
Tungsten CarbidePremium BlockTungsten carbide particles embedded in the tips can extend wear life in validated high-abrasion applications. Final performance depends on material, design, and working conditions.

Quality Control Parameters (MTR Standards)

Our parts meet the strict Mill Test Report (MTR) standards required by professional buyers in Europe, America, and Australia.

Surface Hardness

Standard sweet spot is HRC 48-54 (below 48 lacks wear resistance, above 54 is too brittle). Heavy-duty rock teeth can reach HRC 52-58.

Impact Toughness

≥ 15 J/cm² at room temperature, ensuring no breakage under powerful impacts.

Tensile & Yield Strength

Tensile Strength ≥ 1450 MPa; Yield Strength ≥ 1100 MPa.

Case Depth

Deep quenching requirement of 8mm - 12mm. Even after surface wear, the inner layer remains hard, extending lifespan significantly.

Technical Specifications: Buckets

Bucket designs customized for specific working conditions.

Material Standards

Mainstream: NM400, NM450, NM500 (HBW 450-540). International Equivalent: High-Strength Low-Alloy (HSLA) steel such as CAT AR series.

Capacity & Dimensions

Ranges from 0.9m³ (PC200) to 13.7m³ (PC2000). Quotes require confirmation of Struck vs Heaped capacity. Mounting dimensions are precision-matched.

General Purpose Bucket

Lightweight design optimized for excavating sand, clay, and lighter materials.

Rock Bucket

Thickened bottom and side wear pads, specifically designed for mining, hard soil, and crushed rock excavation.
