工等の加工性にも優れた鋼線に関するものである。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a steel wire with excellent corrosion resistance for use in springs, wire ropes, etc. This invention relates to a steel wire that has excellent workability in wire processing, spring forming, etc.
（従来の技術）
従来、直径が１．０ｍ＋ｗ以下のスプリング用鋼線とし
てはステンレス細線、亜鉛メッキ細線、裸鋼線等が使用
されているが夫々に問題点がある。(Prior Art) Conventionally, stainless steel wires, galvanized wires, bare steel wires, etc. have been used as steel wires for springs with a diameter of 1.0 m+w or less, but each has its own problems.
即ち、ステンレス細線は耐蝕性には優れているが価格が
高く、伸線作業性が悪い等のマイナス面がある。また、
亜鉛メッキ細線は亜鉛の特性上、伸線過程でダイスに焼
付きを起こしたり、ダイス入口で削れが発生したりする
、またメッキ厚みを厚くすると更に伸線が困難となり断
線につながる。That is, fine stainless steel wire has excellent corrosion resistance, but has disadvantages such as high price and poor wire drawing workability. Also,
Due to the characteristics of zinc, galvanized thin wire can cause seizure on the die during the wire drawing process or scratches at the die entrance, and thicker plating makes wire drawing even more difficult and can lead to wire breakage.
このように均一な品質の製品が得られ難く、耐蝕性が悪
い。In this way, it is difficult to obtain a product of uniform quality, and the corrosion resistance is poor.
裸鋼線はスプリングに成形加工後メッキを施されるが、
スプリング成形後のメッキ作業は均一性と作業性に難点
がある。Bare steel wire is plated after being formed into springs.
Plating work after spring forming has problems with uniformity and workability.
他方、耐蝕性向上の目的で各種合金メッキが試みられて
いるが、夫々に問題があり実用化が難しい。−例として

Ｎｉ−Ｚｎ合金メッキはＮｉ％が多くなるに従い硬度が
高くなり、延性が減少するためである。On the other hand, various types of alloy plating have been attempted for the purpose of improving corrosion resistance, but each has its own problems and is difficult to put into practical use. - For example, Ni-Zn alloy plating, which has been put into practical use on steel sheets, has many difficulties in post-processing, especially when drawing the steel wire with a die after applying Ni-Zn alloy plating. This may cause cracking of the plating layer, which may actually impair the corrosion resistance. This is because, as shown in FIG. 1, as Ni-Zn alloy plating increases, the hardness increases and the ductility decreases as the Ni percentage increases.

ものである。(Problems to be Solved by the Invention) The present invention eliminates the problem of steel wire plated with Ni-Zn alloy to improve corrosion resistance, which causes cracks in the plating layer during wire drawing, which impairs the corrosion resistance. It is an object of the present invention to provide a Ni--Zn alloy plated steel wire that is not only excellent in properties but also in processability such as wire drawing and spring forming.

。言い換えれば、Ｎｉ含有量の増加にともない伸線加工
およびコイリング加工の加工性が悪くなる。(Function) Figure 1 shows the relationship between the Ni content of Ni-Zn alloy plating and the plating hardness.As is clear from this Figure, the plating hardness increases as the Ni content increases. . In other words, as the Ni content increases, the workability of wire drawing and coiling becomes worse.

良好な耐蝕性を示し、特に８〜１８％の間で耐蝕性が著
しく優れていることが認められる。Figure 2 shows the relationship between the Ni content and corrosion resistance of Ni-Zn alloy plating, showing good corrosion resistance when the Ni content is in the range of 6 to 25%, and especially in the range of 8 to 18%. It is recognized that the corrosion resistance is extremely excellent.
