Being 750 ± 10 DEG C, temperature retention time is 6-8h, air cooling；Hardening heat 800 DEG C-830 DEG C, temperature retention time 80-150min, water-cooled.
The foundation of the active chemical design of the wear-resistant oxidation-resistant alloy spring steel of the present invention and restriction content range
Reason as follows:
C is impact wear-resistant oxidation-resistant alloy spring steel hardness, the most important element of toughness.Carbon content is high, the most accordingly
Carbide quantity is many, and the hardness of material is high, and wear-resistant antioxygenic property is superior, but toughness reduces, processing difficulties, and in use
Broken；Vice versa.In order to ensure that this alloy spring steel can obtain the spherodized structure that toughness is good in heat treatment process, and
The defects such as crackle are occurred without, within therefore C content is strict controlled in eutectoid steel scope, with 0.360-in the course of processing
0.550% is advisable.

Knit and performance, mainly Precipitation in the ferrite of austenite grain boundary, the operation of rolling can suppress the recrystallization of austenite
And stop crystal grain to be grown up, thus play fining ferrite grains, the intensity improving alloy spring steel and toughness.V content of the present invention
Scope be defined as 0.020-0.100%.
Mn is a kind of useful element in ferrous materials.In this steel, manganese is mainly dissolved in ferrite, forms displacement
Solid solution, and make ferrite strengthen, form alloyed cementite, improve the intensity of alloy spring steel；Meanwhile, Mn energy and alloy spring
Steel inclusion S chemical combination becomes MnS, to alleviate the illeffects of S.The scope of Mn content of the present invention is defined as 0.150-
2.20%.
Cr is medium carbide former, can significantly improve intensity, hardness and wearability.Cr in steel, a part is put
Change ferrum and form alloyed cementite, improve stability；A part is dissolved in ferrite, produce solution strengthening, improve ferritic by force
Degree and hardness.Too high Cr content reduces plasticity and the toughness of alloy spring steel.The scope of Cr content the most of the present invention determines
For Cr:0.700-3.800%.
Ni is non-carbide former.Ni is present in spring steel with solution.With Cr with the use of time, can be notable
Improve the quenching degree of spring steel.Ni reduces the C content of eutectoid point, increases the volume fraction of pearlite, is conducive to improving intensity.Ni
Reduce Ar3 transition temperature, make ferrite crystal grain attenuate, meanwhile, pearlite interlamellar spacing can be made to reduce, beneficially the raising of toughness.
The scope of Ni content of the present invention is defined as 0.300-0.500%.
The selection gist of the technological condition of manufacture method of the present invention is: (Ac3 temperature is to select high hardening heat
810 DEG C), the abundant Solid solution precipitation of mainly useful for carbide, improves spring steel body hardness and the uniformity of tissue, thus improves
The wearability of spring steel.
The invention has the beneficial effects as follows: this spring steel hardness is significantly higher than conventional high duty alloy spring steel, carries greatly
Having risen the anti-wear performance of spring steel, this spring steel processing performance is excellent, can meet tubulation bending requirement, meet the use of product
Requirement.It is suitable for working normally under load environment, to manufacturing spring materials, there is higher yield strength, overcome conventional high-quality
Alloy spring steel hardness is low, the shortcoming that wearability is weak, reduces the consumption of material, improving production efficiency；And there is the longer longevity
Life, its cost performance is high, and the spread being suitable for industry manufacture field uses.
