Description
Technical field
The invention belongs to high-strength spring silk technology field, the high-strength spring wires of more particularly to a kind of high elastic modulus
And preparation method thereof.More particularly to a kind of good high-strength spring wire of high elastic modulus long-time stability and preparation method thereof.
Background technology
Stainless spring has many advantages, such as corrosion-resistant, inoxidizability.It is widely used in electronic apparatus, food industry, chemistry
In the stringent industry of the performance requirements such as industry, textile machine, automobile making and aviation.Manufactured spring is removed with stainless and anti-corrosion
Property outside, there are many more other advantages, such as anti-relaxation (elasticity attenuation) ability than with the spring of spring steel and alloy steel making well very
It is more, it might even be possible to several times high.Since rustproof spring steel is inaccessiable excellent with general carbon spring steel and alloy spring steel institute
More the requirement of performance and certain departments performances such as stainless, anti-corrosion to spring more and more urgently with strictly, particularly tiny spring
Development (common spring gauge of wire be difficult refinement), all so that the application range of rustproof spring steel constantly expands, dosage is not
It is disconnected to increase.Domestic and international widely used stainless spring wire is roughly divided into three classes：Martensite transformation steel wire, working hardening austenitic steel
Silk and precipitation-hardening semiaustenitic steel wire.
For the higher semiaustenitic precipitation-hardening stainless steel of elasticity modulus.It is strong that it has austenitic steel corrosion resistance concurrently, it is cold plus
The advantages of work is functional and martensite steel can pass through heat treatment reinforcement, there is also structure sensitive properties are strong, performance inconsistency is big, should
Power crack propagation is fast, processing technology incorrect the shortcomings of being also easy to produce brittle fracture.Therefore such semiaustenitic precipitation-hardening is stainless
Steel all has very big difficulty in hot-working or cold drawing, this difficulty be mainly manifested in production technology it is incorrect when seriously drop
The plasticity of low material, steel wire and spring are also easy to produce lengthwise crackle, and spring steel wire stress cracking tendency is big.Domestic at present is more
Material be 0Cr17Ni7Al and 0Cr12Mn5Ni4Mo3Al stainless steel wires.Tracking investigation discovery is carried out according to market,
Performance big rise and fall when 0Cr17Ni7Al stainless steel wires preserve for a long time.After preserving 1 year, part silk material can be broken, become fragile,
Can not be around spring phenomenon, craftsmanship is very poor, tissue is unstable；0Cr12Mn5Ni4Mo3Al stainless steel wires spring in Xin Ru factories matches
Qualification rate qualification rate after 90% or so, 1 year drops to 70% or even 50%.The intensity of both B alloy wires is difficult to meet more simultaneously
Add harsh requirement, spring force scattered error is big.It cannot store for a long time at room temperature, it is prone to which stress release cracks, and especially exists
(- 50 DEG C) intensity rank declines more under low temperature.Therefore, it is badly in need of a kind of good high strong spring of high elastic modulus long-time stability
