Abstract
The invention discloses an alloy spring steel which is obtained by carrying out the following steps: material screening, heating, molding, waste heat quenching, medium-temperature tempering and final product molding. The alloy spring steel comprises the following components in proportion: 0.3500% to 0.6500% of C, 0.8000% to 5.4200% of Si, 0.1500% to 2.200% of Mn, 0.003% to 0.08% of P, 0.003% to 0.0800% of S, 0.70% to 3.80% of Cr, 0.0001% to 0.05% of Sc, 0.0005% to 0.0500% of Al, 0.0020% to 0.0100% of N and the balance of Fe and inevitable impurities. The rare earth metal Sc which is added can be used for vulcanizing and refining crystal particles, so that the machining performance of the alloy spring steel is improved. Thus, the alloy spring steel is high in strength, strong in toughness and strong in elastic reduction resistance, thereby being suitable for normally working under a loading environment. In addition, the alloy spring steel is long in service life.
Description
Technical field
The present invention relates to a kind of steel alloy, particularly relate to a kind of high-tenacity alloy spring steel.
Background technology
Spring is elastomerics, and its major function is under load effect, to produce distortion, when removing load, still can return to the original form, and utilizes its storage and the energy that discharges is served for the mankind.It is the critical elements of mechanize, automatization that spring has, and is widely used in the industries such as aerospace, machinofacture, communications and transportation and instrument.Spring steel is because having good elasticity for the manufacture of spring, and the characteristic of its material greatly affects the quality of spring.According to GB/T13304 standard, spring steel is divided into non-alloy spring steel (carbon spring steel) and alloy spring steel according to its chemical composition.Wherein, alloy spring steel, because relaxation resistance, toughness, hardening capacity of having improved significantly spring steel adding of alloying element etc. are with a wide range of applications, is present and the developing direction of following spring steel.Elasticity attenuation is one of form of spring failure, the main method that improves alloy spring steel elasticity attenuation resistance is by increasing silicone content, to improve intensity and the toughness of steel, but the decarburizing tendency when easily forming graphite and cause heating due to silicon, content is unsuitable too high, thereby improving bullet, to subtract the effect of drag very limited, can not meet the service requirements of special conditions lower spring steel.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of snappiness, high tenacity and high-strength alloy spring steel.
Technical problem to be solved by this invention can adopt following technical scheme to realize:
A kind of alloy spring steel, through punishment in advance, heating, moulding, immediate quenching, average tempering, finally carry out formed product, the component of described alloy spring steel and proportioning are: C:0.3500～0.6500%, Si:0.8000～5.4200%, Mn:0.1500～2.200%, P:0.003～0.08%, S:0.003～0.0800%, Cr:0.70～3.80%, Sc:0.0001～0.05%, Al:0.0005～0.0500%, N:0.0020～0.0100%, surplus is Fe and inevitable impurity.
Preferably, described alloy spring steel also comprise in Zr:0.03～1.20%, Cu:0.01～0.20% more than a kind.
Preferably, described alloy spring steel also comprises one kind or two or more in Ca:0.0001～0.0120%, Mg:0.0001～0.0120%, Zr:0.06～0.10%.
