Abstract
The invention discloses a wear-resistant steel main cutter plate used for land levellers, wherein the wear-resistant steel main cutter plate 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, 1.5-2.5% of Sn, 0.8-1.1% of W, 0.6-0.8% of Si, not more than 0.03% of P, not more than 0.02% of S and the balanced Fe. The wear-resistant steel material is excellent in hardness and toughness and is very excellent in wear resistance.
Description
Technical field
The present invention relates to a kind of motorized grader wear resisting steel to operate plate.
Background technology
Motorized grader is one of engineering machinery main in earthwork, wearing and tearing are one of major ways causing this kind of machinery operator blackboard newspaper useless, 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 motorized grader wear resisting steel and to operate plate.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of motorized grader wear resisting steel is operated plate, described wear resisting steel operator 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%, Sn 1.5 ~ 2.5%, W 0.8 ~ 1.1%, Si 0.6 ~ 0.8%, P≤0.03%, S≤0.02%, surplus is Fe.
Further, described wear resisting steel operator 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%, Sn 1.5 ~ 2%, W 1 ~ 1.1%, Si 0.7 ~ 0.8%, P≤0.03%, S≤0.02%, surplus is Fe.
Operate compared with plate with the wear resisting steel of existing motorized grader, wear resisting steel operator plate of the present invention can significantly improve hardness and the toughness of material, alleviates the wearing and tearing of knife plate.
