Abstract
The invention discloses a wear-resistant steel bottom plate for a loader. The wear-resistant steel bottom plate comprises chemical components including, in weight percent, 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, less than or equal to 0.03% of P, less than or equal to 0.02% of S and the balance Fe. The wear-resistant steel bottom plate has fine hardness and toughness and excellent wear resistance.
Description
Technical field
The present invention relates to a kind of shovel loader wear resisting steel base plate.
Background technology
Shovel loader is one of engineering machinery main in earthwork, wearing and tearing are one of major ways causing this kind of power shovel bottom sheet to scrap, 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 shovel loader wear resisting steel base plate.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of shovel loader wear resisting steel base plate, described wear resisting steel base plate 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%, Si 0.6 ~ 0.8%, P≤0.03%, S≤0.02%, surplus is Fe.
Further, described wear resisting steel base plate 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%, Si 0.7 ~ 0.8%, P≤0.03%, S≤0.02%, surplus is Fe.
Compared with the wear resisting steel base plate of existing loading shovel, wear resisting steel base plate of the present invention can significantly improve hardness and the toughness of material, alleviates the wearing and tearing of base plate.
