Abstract
The invention discloses a kind of spring high-ductility alloy material, specifically include the composition of following mass percentage content: C:0.9 1.5%, Mn:0.8 0.9%, Si:0.6 0.8%, Cr:0.8 1.2%, Ni:0.1 0.3%, Cu:0.3 0.7%, Mo:0.2 0.4%, S:0.05 0.07%, P:0.06 0.1%, remaining is Fe and inevitable impurity, and described inevitable content of impurities is less than 0.05%, by the way, the present invention can possess high toughness, thus improve the anti-fatigue performance of obtained spring, have use value height, the feature of life-span length.
Description
Technical field
The present invention relates to a kind of alloy material, particularly to a kind of spring high-ductility alloy material.
Background technology
Spring is a kind of machine components utilizing elasticity to carry out work, and the part made with elastomeric material is sent out under external force
Raw deformation, restores to the original state again after removing external force, and along with the development of science and technology, the usage amount of spring also gets more and more, respectively
The each industry of row is both needed to use spring, and it is more and more higher for the requirement of spring that this result also in people, and spring is during using,
Its toughness, fatigue resistance are particularly significant, therefore need the toughness to spring and anti-fatigue ability to improve.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of spring high-ductility alloy material, it is possible to possess have high
Toughness, thus improve the anti-fatigue performance of obtained spring, the height that has use value, the feature of life-span length.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of spring high tenacity to close
Gold copper-base alloy, specifically includes the composition of following mass percentage content:
C:0.9-1.5%, Mn:0.8-0.9%, Si:0.6-0.8%, Cr:0.8-1.2%, Ni:0.1-0.3%, Cu:0.3-0.7%,
Mo:0.2-0.4%, S:0.05-0.07%, P:0.06-0.1%, remaining is Fe and inevitable impurity, and described can not keep away
The content of impurities exempted from is less than 0.05%.
In a preferred embodiment of the present invention, described inevitable impurity be carbide, sulfide, the one of phosphide
Plant or multiple mixing.
In a preferred embodiment of the present invention, the described single content of inevitable impurity is less than 0.02%.
In a preferred embodiment of the present invention, the content summation of described S, P is less than 0.15%.
The invention has the beneficial effects as follows: the present invention can possess and have high toughness, thus improve the anti-of obtained spring
Fatigue behaviour, the height that has use value, the feature of life-span length.
Detailed description of the invention
Below presently preferred embodiments of the present invention is described in detail so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that thus protection scope of the present invention is made apparent clear and definite defining.

Remaining is Fe and inevitable impurity, and described inevitable content of impurities is less than 0.05%.
Described inevitable impurity is one or more mixing of carbide, sulfide, phosphide.
The preparation method of the present invention a kind of spring high-ductility alloy material is as follows:
(1), weighing each raw material according to aforementioned proportion, in being mixed input high-temperature smelting pot, carrying out high temperature fusion, until being mixed
Close molten metal；
(2), by importing after the slagging-off of above-mentioned hybrid metal liquid in appointment mould, after cooling molding, semi-finished product are obtained；
(3), carry out above-mentioned semi-finished product quenching, be tempered after finally give spring high-ductility alloy material.
Being different from prior art, the present invention can possess and have high toughness, thus improves the resisting fatigue of obtained spring
Performance, the height that has use value, the feature of life-span length.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description is made convert, or are directly or indirectly used in other relevant technology necks
Territory, is the most in like manner included in the scope of patent protection of the present invention.
