| 抄録 | 各種ステンレス鋼線の大気暴露試験を、海岸地区、臨海工業地帯及び郊外の３ヵ所で１０年間に渡り実施した。その結果以下の事がわかった。一般的なオーステナイト系ステンレス鋼線は発錆面積率や孔食密度は小さいが、発生した孔食は深く進行する傾向があるので注意を要する。フェライト系ステンレス鋼線は全面腐食的に進行するので発錆量は多いが、深い孔食はむしろ少ない。発錆面積率の大きい鋼種でも断面減少率はわずかなので引張強度の低下は小さかった｡
暴露地の影響はCl-にさらされる海岸地区で最も劣化が激しく、臨海工業地帯がこれに次いでおり郊外は緩やかであった。 ステンレス鋼線と他金属線と接触させて暴露すると、相手が銅の場合は深い孔食が進み、相手が亜鉛アルミなら防食される傾向にある。 |
| Abstract | The atmospheric exposure test of various
stainless steel wires has been carried out
for ten years in three places, that is, a
coastal area, a coastal industrial zone and
a suburb. As the results, the following facts
were found. In general austenitic stainless
steel wires, the rate of rusted area and
pitting density were small, but the pitting
occurred tended to advance deeply, therefore,
the last quantity was mach, but the deep
pitting was rather few. Even in the kinds
of steel in which the rate of rusted area
was large, the rate of cross section reduction
was slight, therefore, the lowering of tensile
strength was small. As to the effect of the places of exposure, in the coastal area where specimens were exposed to Cl-,deterioration was most severe, the coastal industrial zone followed this, and in the suburb, it was mild. When stainless steel wires were exposed being brought in contact with other metal wires, in the case of the other metal being copper, the deep pitting advanced, and zinc or aluminum, they tended to be protected. |
