Abstract
The invention discloses a composite manganese-steel alloy. The composite manganese-steel alloy is composed of six components in percentage by weight: 14.6-16.2% of manganese, 69.8-74.8% of iron, 2.4-3.3% of carbon, 0.7-1.5% of silicon, 4.9-5.7% of nickel and 2.6-3.5% of molybdenum. By adding the elements such as carbon, silicon, nickel, and molybdenum into the alloy, the self performances, especially strength, low-temperature toughness, processability, weldability, corrosion resistance, heat resistance, abrasion resistance and hardenability and the like, of the alloy can be greatly improved, so that the application range of the manganese-steel alloy is broader.
Description
Technical field
The present invention relates to a kind of alloy, be specifically related to a kind of compound manganese alloy.
Background technology
Manganese steel is a kind of high-intensity anti-manganese steel, is mainly used in withstanding shocks, the bad working environments condition such as extruding, material wearing and tearing, and collapse mode is taking attrition as main.The most important feature of high mangaenese steel is under strong impact, extruding condition, and work hardening phenomenon occurs rapidly on top layer, makes its hardened layer when heart portion still keeps toughness that austenite is good and plasticity have good wear resisting property.This be other material can't be obtained.But the wear resistance of high mangaenese steel just just shows its superiority possessing under the condition that is enough to form work hardening, and other situations are next very poor.
Summary of the invention
The object of the present invention is to provide a kind of intensity high and low temperature good toughness, processibility is good, weldability is high, erosion resistance is strong, heat resistance is high, wear resistance is strong, hardening capacity is good, use range is wide compound manganese alloy.
Technical scheme of the present invention is, a kind of compound manganese alloy, described compound manganese alloy is combined by manganese, iron, carbon, silicon, nickel and six kinds of compositions of molybdenum, in described compound manganese alloy, the shared weight percent of each composition is respectively: described manganese accounts for 14.6%-16.2%, described iron accounts for 69.8%-74.8%, described carbon accounts for 2.4%-3.3%, and described silicon accounts for 0.7%-1.5%, and described nickel accounts for 4.9%-5.7% and described molybdenum accounts for 2.6%-3.5%.
In a preferred embodiment of the present invention, in described compound manganese alloy, the shared weight percent of each composition is specially: described manganese accounts for 14.7%, and described iron accounts for 74.2%, and described carbon accounts for 2.5%, described silicon accounts for 0.8%, described nickel account for 5.1% and described molybdenum account for 2.7%.
In a preferred embodiment of the present invention, in described compound manganese alloy, the shared weight percent of each composition is specially: described manganese accounts for 16.1%, and described iron accounts for 70.3%, and described carbon accounts for 3.2%, described silicon accounts for 1.4%, described nickel account for 5.6% and described molybdenum account for 3.4%.
Of the present invention is a kind of compound manganese alloy, by add the elements such as carbon, silicon, nickel and molybdenum in alloy, the performance of alloy own is improved significantly, especially intensity, low-temperature flexibility, processibility, can Han Xing, the multiple performance such as erosion resistance, heat resistance, wear resistance and hardening capacity, make the use range of manganese alloy more wide.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Of the present invention is a kind of compound manganese alloy, described compound manganese alloy is combined by manganese, iron, carbon, silicon, nickel and six kinds of compositions of molybdenum, in described compound manganese alloy, the shared weight percent of each composition is respectively: described manganese accounts for 14.6%-16.2%, described iron accounts for 69.8%-74.8%, described carbon accounts for 2.4%-3.3%, described silicon accounts for 0.7%-1.5%, and described nickel accounts for 4.9%-5.7% and described molybdenum accounts for 2.6%-3.5%.
Further, in described compound manganese alloy, the shared weight percent of each composition is specially: described manganese accounts for 14.7%, and described iron accounts for 74.2%, and described carbon accounts for 2.5%, and described silicon accounts for 0.8%, described nickel account for 5.1% and described molybdenum account for 2.7%.
Further, in described compound manganese alloy, the shared weight percent of each composition is specially: described manganese accounts for 16.1%, and described iron accounts for 70.3%, and described carbon accounts for 3.2%, and described silicon accounts for 1.4%, described nickel account for 5.6% and described molybdenum account for 3.4%.
Carbon, silicon, nickel and molybdenum can improve the intensity of steel and significantly not reduce its toughness; The brittle transition temperature of steel can be reduced, the low-temperature flexibility of steel can be improved; Improve processibility and the weldability of steel; The resistance to corrosion that improves steel, can not only be acidproof, and the corrosion of energy alkali resistant and atmosphere; Improve steel heat resistance; The effect of anti-hydrogen attack; The multiple performances such as the hardening capacity of raising steel.
Of the present invention is a kind of compound manganese alloy, by add the elements such as carbon, silicon, nickel and molybdenum in alloy, the performance of alloy own is improved significantly, especially intensity, low-temperature flexibility, processibility, can Han Xing, the multiple performance such as erosion resistance, heat resistance, wear resistance and hardening capacity, make the use range of manganese alloy more wide.
The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
