Description
Technical field
The invention belongs to metallurgical technology fields, are related to a kind of low noise stainless steel wire.
Background technology
There are four types of stainless steels, and 1, ferritic stainless steel, corrosion resistance, toughness and solderability are carried with the increase of chrome content
Height, the stress corrosion performance of resistance to chloride are better than other species stainless steels.2nd, austenitic stainless steel, can resistant to many dielectric corrosion.3、
Martensitic stain less steel, intensity is high, but plasticity and solderability are poor.4th, austenite-ferrite two phase stainless steel, have concurrently austenite and
The advantages of ferritic stainless steel, and with superplasticity.
Stainless steel can be fabricated to stainless steel wire, applied to the row such as mining industry, oil, chemical industry, food, medicine, machine-building
Industry.Therefore the performance of stainless steel wire directly affects the performance of stainless (steel) wire.However there is strong for the stainless steel wire on existing market
The shortcomings of low, noise is larger, strong alkali-acid resistance is poor is spent, strongly limits its service life and application range.
Stainless steel drawing is to pull out wire rod or line base from the die hole of wire drawing die under the action of pulling capacity, small disconnected to produce
The steel wire in face or the Metal Forming process of non ferrous wire.The gold of the different section shape and size of various metals and alloy
Belonging to silk can use drawing to produce.The silk of pull-out, accurate size, any surface finish, and drawing equipment used and mold are simple, system
It makes easily.
Stainless steel wire is widely used as constructional steel, in transport, site construction, because the originals such as transport, construction
Because being easy to generate very big noise, so as to bring larger production noise, nearby residents life is influenced, also influences producers
Mood.
The content of the invention
For this reason, it may be necessary to the shortcomings that a kind of noise for stainless steel wire in the prior art is larger is provided, the present invention provides
A kind of stainless steel wire of low noise.
Low noise stainless steel wire provided by the present invention, a diameter of 3~5mm, ingredient percent are：Contain carbon
0.01~0.03%, chromium 18~20%, nickel 7~8%, copper 0.1~0.12%, phosphorus 0.4~0.5%, remaining is iron.
We have discovered that in the steel formed in common iron-carbon, the hardenability of steel can be effectively improved by adding in chromium
With tempering resistance, the intensity of steel is improved, and chromium can also reduce the activity of carbon, improve the leaching carbon of steel, and formed
Fine carbide can reduce steel surface decarburization in heating, rolling and heat treatment process and graphitization tendency, improve toughness and
Low noise damage property；But chromium content it is excessively high when, largely form the carbide of chromium instead, the bullet for deteriorating steel subtracts performance and toughness.
Therefore, in the present invention, the content of chromium in stainless steel is controlled as 13~17% (weight percent), and optimal content is 16%
Meanwhile add in a small amount of nickel, be resistant to various acid corrosions and stress corrosion, and property is tough and tensile, be magnetic with it is good plastic
Property, welding performance might as well；There are higher intensity and anti-oxidant, resistance to combustion gas corrosion ability under 650~1000 DEG C of high temperature.In this hair
In bright, the content for controlling the nickel in steel is 7%~8%, and optimal content is 7.8%.Furthermore it has been found that it adds in micro
Copper, phosphorus can improve the performance of steel atmospheric corrosion resistance.
The present invention a preferred embodiment be：The stainless steel ingredient percent is：Containing carbon 0.01~
0.03%, chromium 18%, nickel 7.8%, copper 0.1%, phosphorus 0.4%, remaining is iron.
Further, it has been found that if adding in micro niobium in the above-mentioned technical solutions, the low of steel can be enhanced
Noise, the study found that reason is that when being heat-treated, the tissue of austenite+carbide is presented in the present invention, carbide
In the presence of, have a significant impact to the corrosion resistance of steel, austenite heats at 450~850 DEG C, due to crystal boundary be precipitated chromium carbide
Cr23C6 so that the chrome content near crystal boundary reduces, and causes intercrystalline corrosion.Therefore, we add in micro niobium wherein, are allowed to
NbC is preferentially combined to form with carbon, stability is high so that chromium retains in the base, avoids crystal boundary chromium depleted, so as to mitigate firm crystalline substance
Boundary's corrosion tendency.It in addition, NbC is precipitated transgranular in Dispersed precipitate, and is not easy to grow up under high temperature, the high temperature of the present invention can be improved
Intensity.For the present invention, when the content of niobium is 0.3~0.8%, the most properly, preferably 0.37%.
A preferred embodiment of the present invention containing chromium be：The stainless steel ingredient percent is：Containing carbon 0.01~
0.03%, chromium 18%, nickel 4%, copper 0.1%, phosphorus 0.4%, niobium 0.37%, remaining is iron.
The invention also discloses the methods that above-mentioned stainless steel wire obtains：It is first pre-processed, then in stainless steel high-speed line
On material milling train, stainless steel billet is rolled to the STAINLESS STEEL WIRE that a diameter of 5.5~6mm is made while hot, by stainless steel wire on Laying head
Material is rolled into the coil of strip that internal diameter is 1000~1100mm；Coil of strip is put into heat-treatment furnace and is heat-treated, with carrying out after heat treatment
Pickling, cold-drawn obtain low noise stainless steel wire.
The pretreatment is raw material proportioning, and mixing is just refined, refining.Raw material is matched by required ingredient herein, so
After mix, just refine, refining, it is described to mix, just refines, refining, be the conventional means of this field, no particular/special requirement.
The heat treatment is 1100 DEG C of temperature, when heat preservation 1.5 is small, water cooling of coming out of the stove；
The acid is a kind of mixed acid, and specially mass concentration is 15% nitric acid and mass concentration is that 5% hydrofluoric acid is made into
Acid.
Two processes are undergone in the cold-drawn, and the first process diameter reduces 1mm, and the second process diameter reduces 0.5mm.
Advantageous effect：Steel wire high temperature resistant provided by the present invention, noise are small, and service life is long.Fundamentally solves steel
The problem of easy noise of silk is larger.Invention increases alloy material classification, the proportional components of a variety of materials element are had adjusted, are being made
Increase nickel, chromium, copper, phosphorus etc. in the material of standby steel wire so that the members such as the nickel containing rational proportion, chromium, copper, phosphorus in stainless steel finished product
Element greatly reduces the noise problem of stainless steel, extends its service life.
