Description
Technical field
The present invention relates to a kind of brassiere Stainless Steel Wire and manufacture method thereof.Be mainly used in weaving, the typing of light industry clothing brassiere, can also be used for connector link, earphone cord, watchband etc.Belong to the metal products technical field.
Background technology
Along with improving constantly of people's living standard, the update of weaving clothing, light industrial goods, civilian Stainless Steel Wire consumption rapid growth.Before 2000, be used to make products such as brassiere, earphone cord both at home and abroad, generally all adopt high-carbon steel wire zinc-plated or zinc-plated, easily come off with for some time coating, not only the surface is not bright and clean attractive in appearance, corrosion easily simultaneously, so a large amount of both at home and abroad Cr-Ni of employing Stainless Steel Wires are made brassiere after 2000, generally all adopt the U.S. ASTM 304H trade mark, its chemical ingredients massfraction is as follows: C 0.04-0.10, Si＜1.00, Mn＜2.00, P＜0.045, S＜0.030, Cr 18.00-20.00, Ni 8.0-11.00.Steel wire diameter is 1.20-3.00mm.
Reach 6000 tons according to statistics China brassiere in 2006 with the Stainless Steel Wire consumption.Because Ni is more rare and expensive metal, it is again strategic resource, the nickel metal price rises suddenly and sharply over nearly 2 years, and the stainless steel price is also along with constantly soaring, for this reason, the stainless steel expert constantly develops a series of novel stainless steel trades mark both at home and abroad, because, satisfying under the product over-all properties prerequisite, also there is no need to use in a large number expensive rare nickel metal, science with Ni, rationally with Ni, to economize on Ni be the task of top priority, also is wise move.Seeking certain element according to above-mentioned theory and partly replace valuable metal Ni, is exactly the starting point and standpoint of patent of the present invention.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of intensity and the solidity to corrosion that both can economize on Ni and steel not only can not reduce high intensity corrosion resistant antibiotic type the brassiere Stainless Steel Wire and the manufacture method thereof that can also suitably improve.
The object of the present invention is achieved like this: a kind of high intensity corrosion resistant antibiotic type brassiere Stainless Steel Wire, it mainly is made up of the alloying element of following massfraction: C 0.60-0.10, Si＜1.00, Mn＜2.00, P＜0.03, S＜0.02, Cr 18.00-20.00, Ni 7.00-8.00, Cu2.0-3.0, N0.10-0.18, surplus Fe and unavoidable impurities.
The theoretical foundation that each alloying element content of the present invention is determined:
Determining of principal element content of the present invention is C, Cr, Ni, N and Cu, and all the other alloying elements are to use content range usually, are not describing in detail at this.
Nickel equivalent:
Numeral before the nickel equivalent=Ni%+30 * % (C+N)+0.5 * %Mn, each element is equivalent to the multiple that Ni forms the austenite ability for this element forms the austenitizing ability.
1) Ni content determines
As seen, Ni is an important element in the austenitic stainless steel from formula, and it is to form austenitic first-selected element, and contribution is many-sided because Ni is to stainless steel, and except forming the austenite, Ni can promote the passivation for stainless steel membrane stability, can improve the solidity to corrosion of steel; Ni can significantly improve the moulding of steel, toughness in addition, can reduce the brittle transition temperature of steel, has anti-low temperature and diamagnetism and improves steel cold formability and weldability etc.So Ni is an indispensable important element in the austenitic steel.But can replace Ni by adding N, obtain identical effect, to add the N element be feasible so Ni suitably falls in the present invention, and the present invention on average reduces by 2% with Ni and suits, and determines that Ni content is that 7.0%-8.0% is feasible.
2) C content determines
C forms the strongest element of austenite ability, is 30 times of Ni.But in austenitic stainless steel, generally do not adopt C as forming austenitic principal element, because, along with the increase of C content, though can improve the intensity of steel, but mould, toughness, solidity to corrosion, cold formability, weldability all will significantly descend, it is generally acknowledged that fraud is far longer than profit, therefore, C content reduces as far as possible, but, can not be too low, otherwise the intensity of steel can not be guaranteed, and it is rational that patent C content of the present invention is defined as 0.06%-0.10%.
3) N content determines
N does not still form one of austenitic strongest element, and simultaneously, N can significantly improve austenitic steel intensity by solution strengthening, simultaneously, can obviously not reduce the moulding of steel, toughness, when N content reaches 0.15% in the steel, be equivalent to 4.5%Ni and form austenitic ability, can improve σ simultaneously
b100N/mm
2In addition, according to anti-spot corrosion equivalent value PRE=Cr%+3.3 * Mo%+16 * N% formula as can be known, it is 16 times more than of Cr that N can improve corrosion-resistant ability.Have, N is blown into N gas when can be by AOD concise again, replaces and blows Ar, improves that N content reaches about 0.20% in the steel, because the N element is taken from the air, the source is abundant, and is cheap, it is convenient to add, and beneficial effect is remarkable, useful N be the wise move of the science of austenitic stainless steel for part Ni.
4) Cr content determines
Cr has absolute effect to the stainless steel solidity to corrosion, increase along with Cr content, the stainless steel solidity to corrosion also improves accordingly, so increase of Cr content, the stainless steel solidity to corrosion also improves accordingly, so the Cr element is an irreplaceable element in the stainless steel, generally is no less than 13%, Cr content of the present invention keeps Cr content range 18.0%-20.0% among the former 304H.
5) Cu content determines
Cu can improve stainless solidity to corrosion.Cu can separate out the intermetallic phase ε of rich Cu on the surface of steel simultaneously, has germ resistance.Solidity to corrosion is more obvious in sulfuric acid in addition, simultaneously, can also improve the plasticity of steel and cold-forming etc., so Cu content is defined as 2.0%-3.0%, also is rational.
The present invention is under the prerequisite that does not reduce Cr content, at first guarantee the rustless property of steel, with N element partial Ni metal, adding simultaneously is not more than 3.0% Cu metal, make the integrated performance index of steel meet or exceed 304H trade mark real standard, the satisfied purposes such as brassiere, earphone cord that are used for.
In sum, it is feasible in the 304H trade mark its main chemical compositions content suitably being adjusted, constant substantially at C content, taking to fall Ni, add N, protect Cr adds under the situation of Cu, both can obtain stable austenite structure, the tensile strength of steel not only can not reduce can also suitably improve 100N/mm
2, solidity to corrosion also can improve simultaneously, and especially having germ resistance is of the present invention one big characteristic, the moulding of steel, tough, cold-workability, weldability all can improve, and satisfy brassiere technology performance requriements fully, so this grade of steel design are rational, science, economical, be suitable for.
Brassiere of the present invention is as follows with the processing step of the manufacture method of Stainless Steel Wire:
Step 1, epithelium are handled, oven dry
Adopt film agent that Φ 5.5mm wire surface is carried out epithelium and handle, then stoving oven oven dry, furnace temperature 100-150 ℃, time 0.5-1.0 hour;
Step 2, rough, take-up
Wire rod after epithelium is handled is multi-pass drawing continuously on drawing wire machine, and first road adopts 30% draft, the draft that successively decreases one by one later on, carry out the 6-7 passes of drawing altogether after, take-up, steel wire is reserved 10-15% and is gently pulled into the product draft before the finished product;
Step 3, clean-out system surface cleaning, continuous oven clean annealing
Adopt the continuous bright heat treatment furnace, at first adopt clear Xian's agent to clean behind the H-wheel unwrapping wire, wash then, dry up and enter tube furnace, 1100 ℃ ± 10 ℃ of furnace temperature, linear velocity 20-30m/ branch feeds ammonia and decomposes back 75%H in the pipe
2, 25%N
2Mixed gas protected, water-cooled, washing, oven dry;
Step 4, oil draw
Adopt the inverted wire drawing machine oil of single pass to draw, draft 10%-15% pulls to trimmed size.
The control of process for making:
Cr, Ni amount influences the cold hardening values of factor K
When Cr content one regularly, along with the reduction of Ni content, add the N element simultaneously after, the cold hardening values of factor K increases, steel wire difficulty relatively when drawing, for example when Cr content 17%, during Ni content 10%, K=12.5; When Ni content 8%, K=14.5; As Ni content 6.5%, K=16.5.Because the increase of K value, the first passes of drawing draft should strengthen, and the present invention's first passes of drawing draft 30%, the draft that successively decreases one by one later on, other passage drafts are by the distribution of successively decreasing, and through the 6-7 passes of drawing, total draft reaches 80%-85%.Through continuous oven clean annealing under the protection of decomposed ammonia body, it is 10%-15% that 1100 ℃ ± 10 ℃ of clean annealing temperature, final finished are drawn the drawing draft through a time oil more then.Technological process control has following four innovative points like this:
1) increase along with hardening coefficient K value, the first passes of drawing draft is increased to 30% by general 20%, is first innovative point of technology controlling and process;
2) the clean annealing temperature is brought up to 1100 ℃ ± 10 ℃ by general 1050 ℃, impels carbon, nitrogen compound fully to dissolve, and especially promotes the rich Cu intermetallic phase of ε to separate out, and helps the antibacterial surface of steel, is second innovative point of technology controlling and process;
3) big draft is adopted in last passage processed oil drawing, and general draft is below 10%, and adopt 15% draft here, thereby the finished product tensile strength of wire be can reach about 1800MPa, be the 3rd innovative point of technology controlling and process;
4) the finished product steel wire adopts inverted drawing wire machine, and adopting lubricant simultaneously is butyrous, thereby it is attractive in appearance to make the finished product steel wire reach light, obtains user's favor, and this is the 4th innovative point of technology controlling and process.
Under the preceding topic of the present invention's chromium stable content in guaranteeing steel (guaranteeing that promptly steel is corrosion-resistant), Ni falls in employing, the method that adds N, simultaneously, making the steel wire process, by increasing means such as total draft and increasing final finished steel wire drawing draft, so the integrated performance index of steel reaches user's service requirements fully, and the cost of steel also is reduced simultaneously.
In sum, the present invention not only saves noble metal Ni, and after adding Cu, N composition, mechanical property, tensile strength have a certain upgrade than the 304H trade mark, also satisfies the requirement of user's technical qualification simultaneously fully.
