Description
本发明涉及一种小直径的不锈钢丝，它具有高的机械性能，主要可用于制造弹簧或使弹性材料强化的钢丝。
具有很高机械性能的细拉拔钢丝是已知的，它由1.4310型(根据标准EN 10088和Pr EN 10270.3)不稳定奥氏体不锈钢构成，其化学成分(重量％)包括Crl6-19％，Ni6-9.5％，Mo≤0.8％，N≤0.11％和C0.05-0.15％。该拉拔钢丝获得的机械性能起因于冷加工和通过此拉丝冷加工产生的α’马氏体的形成。这些钢丝可用于制造弹簧，该弹簧通过钢丝成形，然后消除应力和硬化热处理来获得。这种技术具有至少一个起因于拉拔期间的很大强化的缺点。由于这种强化的程度，当钢丝直径小时，至少需要进行数次交替拉拔和超急冷热处理周期。这使制造复杂化并增加其成本。
已有具有很高机械性能及主要可用于制造弹簧的细拉拔钢丝，它由1.4568型(根据标准EN10088和Pr EN 10270)奥氏体不锈钢组成，该钢丝通过NiAl析出而二次硬化，其化学成分(重量％)包括Cr16-18％，Ni6.5-7.8％和Al0.7-1.5％。这些钢丝也是已知的。
这种技术的优点是可由这样机械性能的钢丝制造弹簧：该钢丝的机械性能大大低于弹簧所需的机械性能，因而这使其很容易进行成形操作。事实上，最终机械性能可通过产生沉淀硬化的时效热处理来获得。另一方面，这种技术首先具有这样的缺点：它采用的钢种含有易氧化或氮化的元素，它导致有害于弹簧疲劳强度的夹杂物的形成，其次，如前述的情况下，这些钢种在拉丝期间产生很大的强化，这就同样需要一系列的交替的拔丝和超急冷处理周期。
本发明的目的是通过提供能沉淀硬化的奥氏体不锈钢丝来克服这些缺点，该钢丝在时效前的冷加工状态下，该钢丝直径在0.4和0.5mm之间时抗拉强度大于2200MPa，直径在0.3和0.4之间时大于2225MPa，直径在0.2和0.3之间时大于2250MPa，直径小于0.2mm时大于2275MPa，并且该钢丝易于拉拔或冷轧。
该钢丝截面可为圆形、椭圆形或多边形，例如三角形、正方形、矩形或六边形。当其截面为圆形时其尺寸按其直径确定；当其截面不是圆形时，其尺寸由截面面积相同的圆截面钢丝直径确定。在所有情况下指的都是钢丝直径。
所以，本发明主题是直径小于2mm，抗拉强度大于2100MPa的不锈钢丝，它由化学成分(重量％)如下元素的钢构成：
0％≤C≤0.03％
0％≤Mn≤2％
0％≤Si≤0.5％
8％≤Ni≤9％
17％≤Cr≤18％
0％≤Mo≤0.4％
3％≤Cu≤3.5％
0％≤N≤0.03％
S≤0.01％
P≤0.04％余为Fe和来自生产时的杂质。
该钢丝主要可用于制造弹簧或用于生产钢丝绳或可构成强化弹性体的钢丝的芯。
本发明还涉及制造本发明钢丝的方法。该方法的要点是提供直径大于或等于5mm的，由奥氏体钢构成的机制钢丝，所述钢的化学成分与上述钢一致，为使该钢丝有完全的奥氏体组织，将此钢丝经超急冷处理，然后酸洗并通过冷塑性变形成形，一般没有中间热处理，或在最小直径的情况下，有中间超急冷，接着是大于300截面收缩。冷塑性变形成形的目的主要是减小截面，任选地使钢丝截面成希望的形状(圆形、方形、三角形等)。该塑性变形可由拔丝、轧制或任何以冷塑性变形来制造钢丝的其它方法来实现。该方法可对强冷加工钢丝进行时效热处理来加以补充，它包括在400-475℃之间的温度下保持5分-3小时之间的时间。
最后，本发明涉及奥氏体不锈钢，其化学成分(重量％)包括：
0％≤C≤0.03％
0％≤Mn≤2％
0％≤Si≤0.5％
8％≤Ni≤9％
17％≤Cr≤18％
0％≤Mo≤0.4％
3％≤Cu≤3.5％
0％≤N≤0.03％
S≤0.01％
P≤0.04％余为Fe和来自生产时的杂质。
现在更准确而没有任何限制地叙述本发明并通过下述实施例来说明本发明。
要制造直径小于或等于2mm的细拉拔钢丝，采用直径大于或等于5mm的，由奥氏体不锈钢制成的机制钢丝，所述钢的化学成分(重量％)包括：
—小于0.03％的C，因为高于它，在拉拔钢丝中出现的高比例的马氏体变得对延迟断裂敏感，然后该弹簧在成形残余应力作用下可能开裂；一般，碳含量大于0.005％，因为在精炼操作时降碳是非常困难的；
—0-2％，最好不大于2％的Mn，与硫结合从而防止低熔点的硫化铬形成；Mn大于2％的钢不经锰再氧化则变得很难脱碳，因此这明显地增加了制造成本；
—Si：0-0.5％，硅的存在(一般大于0.1％)来源于钢的生产过程，它使冷加工钢丝中出现的马氏体大为硬化；为了避免形变操作之前过分硬化，将硅含限制到0.5％；
—8-9％的Ni确保热轧期间和超急冷处理之后的奥氏体组织；
—17-18％的Cr产生足够的耐蚀性，而不使热轧后酸洗产生太多的困难；
—0-0.4％的Mo改善腐蚀性能而不损害其它性能；
—3-3.5％的Cu可使拉丝后的时效处理期间有沉淀硬化；将其含量限制到3.5％，是因为：高于它，铜增加热轧中的困难；
—0-0.03％的N，它来自于生产过程；它的含量一般大于0.005％，且必须保持在0.03％以下，以避免延迟断裂的危险；
—小于0.01％的S，硫是杂质，其含量必须限制，因为其量太大时使此拉拔的钢丝变脆；
—小于0.04％的P，磷是杂质，在热轧期间它可引起缺陷；
余为Fe和来自生产过程的杂质。
所有这些元素对热轧期间和超急冷后的奥氏体组织的稳定性都有影响，还对凝固组织有影响。每个元素的成分范围要这样选择：使凝固组织为铁素体并没有高的偏析。
如本发明人意想不到地观察到的，该钢的优点是：它能通过拔丝和组织硬化而不需要任何中间退火就达到高的机械性能，甚至在直径收缩大于20倍情况下也是这样。
用刚才定义的钢，通过热轧制造直径大于或等于5mm的机制钢丝，然后为使它有完全的奥氏体组织，进行超急冷处理，然后酸洗，该处理的要点在于：加热到800-1250℃之间的温度，接着空冷或更快的冷却。
然后将这样获得的经超急冷和酸洗的机制钢丝以一个或多个步骤，每步几次，拉拔到直径小于2mm，只要将初截面与终截面之比保持至少小于485，则不需要进行中间热处理。要制造最小的直径，特别是小于0.25mm的直径的钢丝，则需要进行中间超急冷以恢复该金属的变形能力。但是，在这种情况下，为了获得需要的机械性能，最终冷加工，就是说在中间超急冷后进行的冷加工，必须与大于300的截面收缩比(终截面/初截面≤1/300)相适应。
为获得合乎要求的最终机械性能，即作为直径的函数的，符合标准的，并列于下表中的抗拉强度，进行时效热处理。
该标准规定的最小抗拉强度
| φmm | 1.5/1.75 | 1.25/1.5 | 1/1.25 | 0.8/1 | 0.65/0.8 | 0.5/0.65 | 0.4/0.5 | 0.3.0.4 | 0.2/0.3 | ≤0.2 |
| RMPa | 1950 | 2000 | 2050 | 2100 | 2125 | 2150 | 2200 | 2225 | 2250 | 2275 |
这种时效处理的要点在于：在400-475℃之间的温度加热5分钟到3小时。它产生源于体心立体结构(拉丝变形诱发α’马氏体)中εCu(c.f.c)析出而导致的硬化，在其它条件相同时，该硬化与α’马氏体含量的变高按比例地增大。
按照设想的用途，时效处理可在拔丝后直接进行，或在钢丝完成其它操作后进行，例如在它被成形以制造螺旋弹簧后进行。
按实施例的方法，由奥氏体不锈钢构成的直径5.5mm机制钢丝开始，按照本发明制造直径1mm、0.5mm和0.25mm的拉拔钢丝，该钢的化学成分(重量％)如下：
| C | Mn | Si | Ni | Cr | Mo | Cu | N | S | P |
| 0.011 | 1.83 | 0.4 | 8.08 | 17.24 | 0.36 | 3.24 | 0.027 | 0.004 | 0.025 |
通过再加热到1080℃再用水冷却对机制钢丝超冷淬火，然后酸洗。
然后将该机制钢丝按下列方案拉拔：
—直径1mm钢丝：按12次从5.5mm降到1mm，
—直径0.5mm钢丝；从1mm的冷加工后的钢丝，以8次从1mm降到0.5mm；
—直径0.25mm钢丝：从1mm的冷加工后的钢丝，以5次从1mm降到0.7mm，接着以8次，从0.7mm降到0.25mm，没有中间热处理。
拉拔后，在435℃保温1小时将钢丝时效。
时效前后获得机械性能(抗拉强度Rm和在0.2％塑性变形时的强度，
Rp0.2)以及α’马氏体含量为：
| 时效前 | 时效后 | ||||
| 直径 | α’％ | RP0.2(MPa) | Rm(MPa) | RP0.2(MPa) | Pm(MPa) |
| 1mm | 52 | 1702 | 1856 | 2070 | 2197 |
| 0.5mm | 65 | 2083 | 2291 | 2668 | 2723 |
| 0.25mm | 75 | 2580 | 2666 | 3076 | 3095 |
用这样获得的钢丝制造上述的弹簧呈现出的性能的优点是：至少等于按1.4310标准牌号钢制造的弹簧的性能，及相等的或甚至是改进的回复能力，同时能简单和成本低地制造。
因为它们的这些性能，本发明钢丝还可用来制造增强弹性体，例如生产增强轮胎的钢丝。这些增强钢丝包括用本发明的拉拔钢丝构成的芯，该芯用如镍和黄铜镀覆(该镀层是用来保证与橡胶生产好的结合的)。
