The following is a non-magnetic material containing silicon 1.00% or less, manganese 2.0+] In order to easily process special steel into caulked caps, it is necessary to adjust the tensile strength, elongation, and hardness of the metal. Therefore, as a result of manufacturing an ideal special steel that has each component within the above-mentioned range and can be easily processed, it was found that the steel was composed of the ratios shown in the lower row of Table 1.

階に於て破損を招き易いという欠点が生じた。We experimented by increasing and decreasing the ratio of each component within the range of the numerical values shown in the upper row of Table 1, that is, the numerical values to ensure non-magnetic properties, but we found that the elongation decreased, etc. However, there was a drawback that it was easy to cause damage.
よって、表−１の下段に示す比率て構成することが最良
であるという実験結果を得ることが出来た。Therefore, it was possible to obtain an experimental result that the configuration shown in the lower part of Table 1 is the best.

る。f) Effects of the Invention As described above, the crimping cap according to the present invention is non-magnetic, unlike conventional caps. Therefore, during indwelling of the indwelling needle in which the catheter and the catheter hub are joined and fixed by the caulking cap according to the present invention, the iron content of the medical drug solution does not adsorb to the caulking cap, and the medical drug solution flows smoothly.
この効果はカテーテルやカテーテルハブの内径に比べ最
も小内径のカシメキャップ部分で発揮されるものである
だけに、医療上極めて有意義なものである。This effect is extremely significant medically because it is exhibited at the caulking cap portion, which has the smallest inner diameter compared to the inner diameter of the catheter or catheter hub.
