Abstract
The invention discloses a wear-resistant relieved tooth prepared from high-strength alloy steel, which is characterized in that the material of the wear-resistant relieved tooth prepared from high-strength alloy steel is alloy steel. The wear-resistant relieved tooth prepared from high-strength alloy steel comprises C, Cr, Mn, Mo, Ni, Si, S, P and Re. The alloy steel material adopted by the wear-resistant relieved tooth prepared from high-strength alloy steel has the advantages of better mechanical properties, higher impact toughness, higher hardness, better antiwear property and wide market prospects.
Description
Technical field
The present invention relates to a kind of high strength alloy steel Antiwear dipper teeth, belong to the forming materials technical field.
Background technology
Mining site is had an opencast mining of the used teeth of ore, is protected tooth, sheath, because wear resisting property is poor, hardness is not enough, all need every day to change, not only increase the replacing time but also increase production cost, therefore, need research and development high strength, high tenacity, high wear-resistant special steel badly as dipper tooth material, to improve the productivity effect of mining site.
Summary of the invention
Technical problem to be solved by this invention provides the high strength alloy steel Antiwear dipper teeth, has higher intensity, toughness and resistance to abrasion.
For solving the problems of the technologies described above, the invention provides a kind of high strength alloy steel Antiwear dipper teeth, it is characterized in that high strength alloy steel Antiwear dipper teeth material is a steel alloy, comprise C, Cr, Mn, Mo, Ni, Si, S, P, Re element in its Chemical Composition.
The content of each element is respectively: C:0.15%～0.20%, and Cr:20%～25%, Mn:4.5%～6.5%, Mo:1.0%～1.5%, Ni:3.00%～4.50%, Si:0.3%～0.5%, S, P :≤0.030%, Re:0.2%.
The beneficial effect that the present invention reached:
The alloy steel material that high strength alloy steel Antiwear dipper teeth of the present invention adopts has better mechanical property, and impelling strength is stronger, and hardness is higher, and resistance to abrasion is better, and market outlook are very wide.
Embodiment
Below the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
High strength alloy steel Antiwear dipper teeth material of the present invention is a steel alloy, comprises C, Cr, Mn, Mo, Ni, Si, S, P, Re element in its Chemical Composition.
The content of each element is respectively: C:0.15%～0.20%, and Cr:20%～25%, Mn:4.5%～6.5%, Mo:1.0%～1.5%, Ni:3.00%～4.50%, Si:0.3%～0.5%, S, P :≤0.030%, Re:0.2%.
Mechanical performance index is: impelling strength 〉=45J/cm
2, yield strength 〉=430, unit elongation 〉=25%, hardness is 350HS.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
