ていた。2. Description of the Related Art Generally, as a material used for electron gun parts such as a grid of an electron gun used for a picture tube or the like, for example, glass sealing is used or color shift due to thermal expansion during use is prevented. In order to perform the above, it is necessary that the thermal expansion coefficient is close to that of these materials, or the thermal expansion coefficient is low, such as Fe-42 wt% Ni and Fe-29 wt% Ni-17 wt% Co. A low thermal expansion alloy was used.
【０００３】これらのグリッドは、従来、例えば次のよ
うに製造されている。Conventionally, these grids are manufactured, for example, as follows.
【０００４】すなわち、鋳造，鍛造，熱間圧延，冷間圧
延などを行い、所定の厚さにした後、プレスなどの打抜
き加工により所定形状に打抜き完成させる。That is, casting, forging, hot rolling, cold rolling, etc. are performed to obtain a predetermined thickness, and then punching is performed by a press or the like to complete punching into a predetermined shape.

【発明が解決しようとする課題】ところで、このように
打抜き加工により所定の形状にする場合には、プレス条
件や合金の機械的特性を変化させても打抜いた部品の端
部に微小なバリの発生は防止できないのが現状である。By the way, in the case of forming a predetermined shape by punching as described above, even if the press condition or the mechanical characteristics of the alloy is changed, a minute burr is formed on the end of the punched part. The current situation is that it is impossible to prevent the occurrence of.
【０００６】しかし、微小なバリでも、発生すると電子

た打抜き性に優れた合金が強く望まれていた。However, even if a minute burr is generated, it adversely affects the characteristics of the electron gun part, for example, the withstand voltage of the electron gun is lowered due to discharge from the minute burr due to a high voltage, and the life of the die is reduced. Therefore, an alloy having a specific coefficient of thermal expansion and suppressing burr formation and having excellent punchability has been strongly desired.

目的とする。The present invention has been made in order to solve the above-mentioned conventional problems, and remarkably improves the punching property, suppresses the occurrence of burrs during punching, and has an excellent electron gun characteristic. An object is to provide an Fe-Ni alloy for parts.
【０００８】[0008]
【課題を解決するための手段と作用】本発明の第１の発
明である電子銃部品用Ｆｅ−Ｎｉ系合金は、Ｎｉ25〜55
重量％、Ｓ 0.002〜0.05重量％を含有し、その他不可避
的に混入する不純物を除き、残部が実質的にＦｅからな
ることを特徴とするものである。Means and Actions for Solving the Problems The Fe-Ni alloy for electron gun parts according to the first invention of the present invention is Ni25-55.
%, S 0.002 to 0.05% by weight, and the balance is substantially Fe, except for impurities that are inevitably mixed.
【０００９】また、本発明の第２の発明である電子銃部

〜0.05重量％、Ｍｎ 0.1〜１重量％を含有し、その他不
可避的に混入する不純物を除き、残部が実質的にＦｅか
らなることを特徴とするものである。The Fe-Ni alloy for electron gun parts, which is the second invention of the present invention, contains 25 to 55% by weight of Ni and S 0.002
.About.0.05% by weight and Mn 0.1 to 1% by weight, and the balance is substantially Fe except for impurities which are unavoidably mixed.
【００１０】本発明の電子銃部品用Ｆｅ−Ｎｉ系合金
の、組成限定理由は下記の通りである。The reasons for limiting the composition of the Fe-Ni alloy for electron gun parts of the present invention are as follows.
【００１１】まず、Ｎｉは、その量があまり少なくて
も、逆にその量があまり多くても、熱膨張係数が目的と
する封着用ガラス材料などと近似する値が得られないた
め、そのＮｉの量は25〜55重量％とした。好ましくは35
〜52重量％である。First, even if the amount of Ni is too small, or conversely, if the amount is too large, the coefficient of thermal expansion cannot obtain a value close to that of the target glass material for sealing, etc. Was 25 to 55% by weight. Preferably 35
~ 52% by weight.
【００１２】また、Ｓは、その量があまり少ないと本発
明の効果が十分に得られず、逆にあまりその量が多いと
脆くなり過ぎて、熱間加工などの加工等に際して割れな
どの問題を生じるため、そのＳの量は 0.002〜0.05重量
％としてた。好ましくは 0.005〜0.02重量％である。If the amount of S is too small, the effect of the present invention is not sufficiently obtained, and if the amount of S is too large, it becomes too brittle, and problems such as cracks occur during processing such as hot working. Therefore, the amount of S was set to 0.002 to 0.05% by weight. It is preferably 0.005 to 0.02% by weight.
【００１３】なお、本発明においてＦｅまたはＮｉ中に
Ｓが不純物として含有されている場合には、その不純物
としてのＳの量も含めて、上記含有量の範囲内になるよ
うに調節する。In the present invention, when S is contained in Fe or Ni as an impurity, the amount of S as an impurity is adjusted to be within the above range.
【００１４】このように、Ｆｅ−Ｎｉ系合金に上記範囲
内で少量のＳを含有させ、このＳまたはＳ化合物を粒界
または粒内の組織内に均一に分散させることによって、
合金に適度の脆さが生じ、プレス加工などに際して打抜
き性のみが向上し、部品の端部のバリの発生を有効に防
止することができる。As described above, a small amount of S is contained in the Fe-Ni alloy within the above range, and the S or S compound is uniformly dispersed in the grain boundaries or the structure within the grains.
Appropriate brittleness occurs in the alloy, only punchability is improved during press working and the like, and it is possible to effectively prevent the occurrence of burrs at the end of the component.
【００１５】また、本発明のＦｅ−Ｎｉ系合金には、上
記元素の他に、さらにＭｎを打抜き性をさらに向上させ
る目的や加工性向上のために 0.1〜１含有することがで
きる。好ましいＭｎの量はＳの含有量との兼ね合いもあ
るが0.15〜0.8 重量％である。In the Fe-Ni alloy of the present invention, in addition to the above-mentioned elements, 0.1 to 1 Mn can be contained for the purpose of further improving the punchability and the workability. The preferable amount of Mn is 0.15 to 0.8% by weight, although it depends on the content of S.
【００１６】このＭｎの含有量が、 0.1重量％であると
熱間加工性が向上し、１重量％以下では熱膨張係数が小
さくなるという傾向が生じ好都合である。If the Mn content is 0.1% by weight, the hot workability is improved, and if it is 1% by weight or less, the coefficient of thermal expansion tends to be small, which is advantageous.
【００１７】このように、さらにＭｎを含有させること
によって、粒界や粒内にＭｎＳが均一に分散し、切削性
が向上し、プレス加工などに際して打抜き性のみが向上
し、部品の端部のバリの発生を有効に防止することがで
きる。As described above, by further containing Mn, MnS is uniformly dispersed in the grain boundaries and grains, the machinability is improved, only the punching property is improved in the press working, and the end portion of the component is improved. Burrs can be effectively prevented.
