Abstract
The invention discloses a wear-resistant bucket tooth for an excavator, wherein the wear-resistant bucket tooth includes following chemical components, by weight: 2.2-2.5% of C, 8.5-11% of V, 5-6.5% of Cr, 2-3% of Ni, 0.8-1.1% of Mn, 0.6-0.8% of Si, not more than 0.03% of P, not more than 0.02% of S and the balanced being Fe. The wear-resistant bucket tooth is excellent in hardness and toughness and is quite excellent in wear resistance.
Description
Technical field
The present invention relates to a kind of excavator wear-resistant bucket tooth.
Background technology
Excavator is one of engineering machinery main in earthwork, and bucket tooth is one of frayed more serious part on excavator, in use not only to be subject to the strong wear of the abrasive particles such as sandstone, but also the intense impact of large stone will be subject to, therefore, when select materials, need hardness and the toughness of considering material, to reduce wearing and tearing and the fracture of material.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of excavator wear-resistant bucket tooth.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of excavator wear-resistant bucket tooth, described wear-resistant bucket tooth is containing the chemical composition of following weight percentage: C 2.2 ~ 2.5%, V 8.5 ~ 11%, Cr 5 ~ 6.5%, Ni 2 ~ 3%, Mn 0.8 ~ 1.1%, Co 0.5 ~ 1%, Si 0.6 ~ 0.8%, P≤0.03%, S≤0.02%, surplus is Fe.
Further, described wear-resistant bucket tooth is containing the chemical composition of following weight percentage: C 2.3 ~ 2.5%, V 8.5 ~ 11%, Cr 6 ~ 6.5%, Ni 2.5 ~ 3%, Mn 1 ~ 1.1%, Co 0.8 ~ 1%, Si 0.7 ~ 0.8%, P≤0.03%, S≤0.02%, surplus is Fe.
Compared with the wear-resistant bucket tooth of existing power shovel, wear-resistant bucket tooth of the present invention can significantly improve hardness and the toughness of material, alleviates the wearing and tearing of bucket tooth.
