電子銃電極用合金を提供することを目的としている。However, due to the recent rapid progress of high definition and high brightness in CRTs for computers, materials with further improved deep drawing properties and burring properties have been demanded. Was. That is, in order to further improve the focus characteristics of the electron gun,
It has become necessary to process the electrode lens with a larger diameter and with higher precision. As a result, the demands for deep drawability and burring properties have become more stringent than ever before, and in the case of conventional alloys, a decrease in yield due to increased manufacturing defects has become inevitable. In recent years, demands for cost reduction have been increasing. However, when the content of expensive Ni is reduced, deep drawability and burring property are deteriorated. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an alloy for an electron gun electrode that can meet the demands for deep drawing and burring properties that have become more severe in recent years.

る。Means for Solving the Problems The inventor of the present invention has conducted intensive studies on the components of materials in order to improve the deep drawability and the burring properties. P, N, Ti, Nb, V, Zr,
Attention was paid to the influence of Ca and Mg. S is conventionally known as an element to be avoided which lowers hot workability and corrosion resistance, and it has been recognized that the lower the S content, the better the deep drawability and burring property. In Japanese Patent Publication No. 4-43372 proposed earlier by the present applicant,
It is said that the reduction of S contributes to the improvement of the deep drawing property and the burring property. Also, the applicant has filed Japanese Patent Application No. 6-33686.
The alloy containing an appropriate amount of S proposed in No. 6 has improved punchability by uniformly dispersing S or an S compound (mainly MnS) in a grain boundary or in a grain.

I discovered that. Therefore, it is desirable to contain an appropriate amount of S also from the viewpoint of the burring property.
When it is specified, the management of the raw material becomes difficult and the desulfurization cost increases. Therefore, as a result of intensive studies by the present inventors, P, N,
When the components including Ti, Nb, V, Zr, Ca, and Mg were strictly defined, it became clear that the upper limit of S was not necessarily required to be 0.003%.

Test materials having the components shown in Table 1 were cast by VOD or vacuum melting to produce 18 types of ingots. These ingots were subjected to forging, peeling, hot rolling and pickling, and then cold rolling and annealing were repeated to produce a 0.4 mm thick annealed material. At that time, the final crystal grain size was adjusted so as to be all 8.0 in grain size number. A deep drawing test was performed on these plates, and the respective limit drawing ratios (LDR) were measured. In addition, a hole expansion test was performed on the plate, and this was used as a guide for evaluating the burring property. In the hole expanding test, a blank having a diameter of 10 mm was expanded with a conical punch having a cutting edge angle of 60 °, and the hole diameter before and after a hole was cracked was measured. The burring property was evaluated by the hole expansion limit λ calculated by the following equation. Incidentally, the following formula h 0 is blank diameter, h 1 is the hole diameter at break.

電極合金として最適である合金を得ることができる。As described above, according to the present invention, S
And Mn content within the above range, and Al,
Since the content of elements that have not been considered in the past such as O is strictly defined, it is possible to meet the demands for deep drawing and burring properties which have become more severe in recent years, and it is optimal as an electron gun electrode alloy. An alloy can be obtained.
