耐食性に問題点があった。(Prior art) Fe and Ni 50% (hereinafter simply abbreviated as "%")
PB class permalloy containing a certain amount of metal is often used as a magnetic shielding material because of its alloy's excellent properties such as high magnetic permeability and large magnetic flux density. However, this alloy had problems with corrosion resistance, such as easy rusting in the atmosphere.
特に、製品の製造工程における発錆は、工程の簡略化、
歩留りの向上を阻害しコストアップにつながっていた。In particular, rusting in the product manufacturing process can be prevented by process simplification,

Fe-Ni as No. 6 (Japanese Patent Application Laid-open No. 60-159157)
We proposed an Fe-Ni alloy with improved hot workability by adding B and Ti to the base alloy. However, although this alloy has improved hot workability, it lacks the magnetic properties such as magnetic permeability and magnetic flux density that a magnetic alloy should have, and is used in high-sensitivity relays, CPU memory, and electromagnetic shielding materials. Further improvements were desired for use in applications such as this.

Although improvements in corrosion resistance and hot working properties have been achieved by adding Cr, B, and Ti, no consideration has been given to obtaining even higher magnetic properties as mentioned above.
What is desired is something that improves both of these characteristics. An object of the present invention is to propose a Fe--Ni--Cr based corrosion-resistant magnetic material that can meet these demands.

（作 用）
まず、本発明磁性材料の成分組成を限定した理由を述べ
る。(Function) First, the reason for limiting the component composition of the magnetic material of the present invention will be described.
Ｎｉの含有量を３５〜６５％と限定したのは、３５％よ
り少ないとパーマロイ並の磁気特性を満足しないからで
あり、一方Ｎｊが６５％より多いと高価になるとともに
Ｃｒ無添加でも十分な耐食性を示すから、Ｃｒ添加の効
果がな（なることを意味する。The Ni content was limited to 35 to 65% because if it was less than 35%, it would not satisfy the same magnetic properties as permalloy.On the other hand, if the Nj content was more than 65%, it would be expensive and it would not be sufficient even without the addition of Cr. Since it exhibits corrosion resistance, it means that the effect of Cr addition is negligible.
Ｃｒの含有量を１〜１５％に限定したのは、１％より少
ないと十分な耐食性を示さず、一方１５％より多いと磁
気特性の劣化が激しいからである。The reason why the Cr content is limited to 1 to 15% is because if it is less than 1%, sufficient corrosion resistance will not be exhibited, whereas if it is more than 15%, the magnetic properties will deteriorate severely.
Ｂの含有量を、０．００１〜０．１％と限定したのは、
０．００１％より少ないと熱間加工性の改善が十分では
なく、０．１％より多いとより以上の熱間加工性の改善
効果はないからであり、加えて磁気特性の劣化も激しく
なるためである。The content of B was limited to 0.001 to 0.1% because
This is because if it is less than 0.001%, the improvement in hot workability will not be sufficient, and if it is more than 0.1%, there will be no further improvement in hot workability, and in addition, the deterioration of magnetic properties will be severe. It's for a reason.
Ｓｉ、 Ａｌ、 Ｖ、 Ｎｂ、 Ｔａ、 Ｔｉ、および
Ｗより選ばれたいずれか一種又は二種以上の元素を０．
５超〜５％以下の範囲で添加することとした理由は、０
．５％以下だと十分な磁気特性改善の効果が望めず、一
方５％を超えると透磁率に関しては改善されるが、磁束
密度の低下が著しくなるためである。One or more elements selected from Si, Al, V, Nb, Ta, Ti, and W are added in an amount of 0.
The reason why we decided to add it in the range of more than 5% to less than 5% is that
．． If it is less than 5%, no sufficient effect of improving the magnetic properties can be expected, whereas if it exceeds 5%, although magnetic permeability is improved, the decrease in magnetic flux density becomes significant.
Ｂの含有量については、熱間加工性改善のために最低０
．００１％は必要とし、一方０．１％を超えて含有させ
ると磁気特性に一部悪影響が出るので、ｏ、ｏｏｉ〜０
．１％の範囲とすることが必要である。The B content should be at least 0 to improve hot workability.
．． 0.001% is necessary, and on the other hand, if it is contained in excess of 0.1%, the magnetic properties will be partially adversely affected, so o, ooi ~ 0
．． It is necessary to set it within the range of 1%.

る。After pickling, cold rolling is performed to obtain an appropriate thickness. After that, this rolled material is heat treated in a high vacuum, or Nz, H
z, NH3, Ox, H2O, Cot, Co, and Ar in a mixed gas that combines one or more of ordinary hydrocarbon gases such as methane gas and ethane gas, or in a trace atmosphere of these gases. B removal treatment is performed by performing heat treatment in a vacuum. These heat treatments are desirably carried out at 900 to 1300°C, and the time is 3
0 minutes to 24 hours is suitable. In addition, when the heat treatment is performed in the above atmospheric gas, Bi in the alloy decreases, and as will be explained in conjunction with the examples described later (Table 2 +1kL14~1
7) The deterioration of magnetic properties caused by B can be canceled out.

片を製作した。(Example) Test materials having the component compositions shown in Table 1 were melted into ingots weighing approximately 10 kg each. This ingot was forged into a slab with a thickness of about 1011 mm, and then hot rolled into a plate with a thickness of 511 mm. Furthermore, it was cold rolled to a thickness of 1m.
It was made into a plate of l. From this plate, the inner diameter is 33 φ and the outer diameter is 45 fin φ.
The magnetic properties of the rings were measured after heat treatment in a high vacuum, in an atmosphere of a single gas or a mixture of gases, and in an atmosphere close to vacuum containing a small amount of a single gas or a mixture of these gases. In addition, a 50 mm x 50 m test piece was manufactured for corrosion resistance testing.

により行った。その実験結果を第２表にまとめて示す。The hot workability was evaluated by performing a tensile test at 1000° C. in the air and determining the reduction percentage of the fracture surface. Corrosion resistance was evaluated by exposing test pieces outdoors for one week and visually observing the state of rust. The experimental results are summarized in Table 2.
第２表より分るように、Ｃｒを３％以上含有する患２〜
１８の本発明材料では、耐食性に対してＣｒ添加の効果
が顕著に現れている。As can be seen from Table 2, cases 2 to 3 containing 3% or more Cr
In No. 18 materials of the present invention, the effect of Cr addition on corrosion resistance is remarkable.

に、Ｓｉ以外の副成分を添加した隘８〜Ｉ３の本発明材
料は若干熱間加工性が劣るものの、操業上支障のない程
度の値を得ている。The effect of B addition on hot workability is 90% or more with addition of about 0.01%, as shown in the reduction of area of N11-6 heat-treated in high vacuum at 1000℃, and as Cr increases, the reduction of area increases slightly. It can be seen that although the value decreases, it shows a remarkable improvement compared to the aperture (ti! of about 20%) of Comparative Material Light 19 containing 5% Cr and no B. 08%) and contains no Si at all, B
In the case of the material of No. 20 containing about 0.0095%, the aperture value is 99%, and when compared with the aperture value of 30% of the material of No. 21, which does not contain Cr, Si, or B, it can be seen that the effect is remarkable. Furthermore, although the materials of the present invention in Nos. 8 to 13 in which subcomponents other than Si were added had slightly inferior hot workability, they obtained values that did not cause any operational problems.

初沈透磁率改善効果はＳｉを単独添加した１１ｈ７の材
料に較べると劣っている。Regarding magnetic properties, for example, Si-added
Comparing with Ih7, it can be seen that the initial sinking permeability of floor 7, which has a large amount of Si, is increased. Similar effects were observed for materials Nos. 8 to 12 to which elements other than Si were added as subcomponents (magnetic permeability improving components) and materials No. 11h13 to which Si and AI were added in combination. However, the effect of improving the initial settling magnetic permeability when the same amount is added is inferior to that of the 11h7 material in which Si is added alone.

れたためと考えられる。Nos. 14 to 17 were heat-treated in one or two mixed gases of COz+CL (9:1), and N1114 was heat-treated in a near-vacuum atmosphere containing trace amounts of these gases.
The Bi content is lower than that of the same composition heat-treated in a high vacuum without such a gas atmosphere (for example, No. 3), and this effect is evident in terms of the initial sinking permeability. In addition, the magnetic properties of the same sample material are B with the same amount of Cr and Si.
This is considered to be because the structure was cleaned by the heat treatment in the atmosphere.
Ｂ添加による磁気特性への影響としては、第２表の１１

As is clear from the comparison between h3 and 19, the initial sinking permeability decreases in the case of B-containing materials. However, with regard to magnetic flux density, no adverse effect due to the addition of B was observed. Also, the presence or absence of subcomponents can be checked, for example, by comparison materials! 1k11B
