を示している。In addition, in Figure 3, which shows the relationship between the dezincification corrosion depth of plate material and the number of cycles, which was created based on the above corrosion test,
When fixing b made of SUS 430 is used for 45 cycles or more, the corrosion of the seat plate 4 becomes more severe compared to fixing a made of SUS 410 and fixing C made of tongue sheet, and when it is made of 90 cycles or more, the corrosion progresses almost completely. Indicates that it will stop. On the other hand,
It is shown that when the fixing a of the present invention is used, there is almost no effect of corroding the seat plate 4, similar to the normal tongue seat C.

It has been found that not all SUS materials are suitable as they may cause corrosion.
そして、ＳＵＳ４１０は、フィキシングの腐蝕が現状の
タンシートに比し少なく、而も座板の脱亜鉛作用が殆ど
なく、樹脂製タンク付ラジェータのフィキシングとして
最も好ましいものであることが確認された。It was confirmed that SUS410 is the most preferable fixing for a radiator with a resin tank because the corrosion of the fixing is less than that of the current tongue sheet, and there is almost no dezincing effect on the seat plate.
