Abstract
The invention relates an alloy steel. The alloy steel contains the following components in percentage by mass: 0.56-0.64% of carbon, 1.2-1.6% of silicon, 0.4-0.6% of manganese, 0.4-0.8% of chromium, 0.1-0.2% of vanadium, 0.08-0.15% of tungsten, and the balance of iron. The material proportion of the alloy steel is changed, the manganese content is appropriately reduced, and refinable grains of rare metal elements such as chromium, vanadium and tungsten are appropriately added, so that excellent heat treatment performance is obtained, the overheating sensibility and the decarburizing tendency of the steel are lowered, the phenomenon of graphitization of a steel material in the process of heat treatment is greatly decreased, the surface quality is improved, the toughness, the strength, the elastic limit and the fatigue strength of the material are increased, the phenomenon of quenching crack is reduced, and the alloy steel can be applied to high-grade spiral springs.
Description
Technical field
The present invention relates to a kind of steel alloy.
Background technology
Produce at present plane scroll spring steel used and mainly contain two kinds: 65Mn Manganese Spring Steel and 60Si2MnA silicon-manganese spring steel.There is easier decarburization, had the shortcomings such as thermo-responsive and temper brittleness in 65Mn Manganese Spring Steel, easily cracks, and this material is mainly used in requiring low plane scroll spring.60Si2MnA silicon-manganese spring steel improves the hardening capacity of spring steel by adding two kinds of elements of silicomanganese, promote hardness, intensity, elastic limit, yield tensile ratio and fatigue strength and temper resistance and the oxidation-resistance of material, become most widely used plane scroll spring material at present, but the raising of silicone content, easily produce greying phenomenon and increase surface decarburization tendency, in steel, easily generate more Silicate Inclusions special, easier hardening break, also limits the application of 60Si2MnA material aspect high-end plane scroll spring.
Summary of the invention
Technical problem to be solved by this invention is to overcome the above-mentioned deficiency of prior art and a kind of steel alloy is provided, and its over-all properties is got a greater increase, and can be used in and manufactures high-end plane scroll spring.
The present invention solves the problems of the technologies described above adopted technical scheme:
, its mass percent is composed as follows:
Carbon 0.56 ~ 0.64%
Silicon 1.2-1.6%,
Manganese 0.4-0.6%,
Chromium 0.4-0.8%,
Vanadium 0.1-0.2%,
Tungsten 0.08-0.15%,
All the other are iron.
The present invention is by changing the proportioning of alloy steel material, suitably reduce the content of silicomanganese, appropriateness is added the yttriums such as chromium, vanadium, tungsten can crystal grain thinning, obtain good heat treatment performance, reduce superheated susceptivity and the decarburizing tendency of steel, significantly reduce the greying phenomenon of steel in heat treatment process, improve surface quality, improve toughness, intensity and elastic limit and the fatigue strength of material, reduced the phenomenon of hardening break, can be applied to high-end plane scroll spring.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
For obtaining meeting the alloy steel material of performance requriements, guarantee that scroll spring can meet requirements of one's work under different condition, the present invention, by changing the micro-ratio in steel alloy, obtains an embodiment 1-6 alloy steel product, and it specifically forms in Table 1.
The steel alloy of table 1 clockwork spring common used material and the present embodiment forms
The alloy steel material that table 1 is obtained is made scroll spring, obtains the performance of product in Table 2.
The performance comparison of table 2 current material and embodiment of the present invention alloy material
From table 2, can see, its tensile strength of the alloy steel material that embodiments of the invention 1-6 obtains, yield-point, clockwork spring life-span, toughness are significantly improved, and have reduced decarburizing tendency.
Claims (1)
1. a steel alloy, is characterized in that: its mass percent is composed as follows: carbon 0.64%, and silicon 2.0%, manganese 0.6%, chromium 0.4%, vanadium 0.2%, tungsten 0.15%, all the other are iron.
