Corrosion (rusting) We are surrounded every day by many steel objects in diverse shapes that are used for various purposes. A massive amount of steel is used in large structures (bridges, ships, vehicles, and buildings), oil well casings and pipelines, and automobiles and electric appliances. However, steel is intrinsically corrosive (rusty) if corrosion prevention measures are not employed. Corrosion protection methods There are roughly four corrosion protection methods: Coating, the use of special steel stock (with corrosion-resistant materials), the use of electricity, and environmental improvement....

Atmospheric corrosion Atmospheric corrosion Nickel-based High Weather-resistant Steel Coating Cycle Extension Steel Applicable standard NAW-TEN complies with JIS G 3114, with the chemical components excluded. TM Small-scale exposure test results 0.10 - Abnormal corrosion Hydrochloric acid interface (Conventional steel) Steel Becoming an alkaline interface (NAW-TEN) Rust has a two-layer structure; If the inner layer rust is stable and solid, the progress of corrosion is inhibited. Conventional steel: CI- becomes hydrochloric acid, causing abnormal corrosion. Hokuriku Shinkansen Hokurikudo Overbridge...

Atmospheric corrosion High Weather-resistant Steel Atmospheric corrosion Catalog QR code Vintage COR-TEN COR-TENTM is equivalent to SMA400W to 570W for JIS G 3114, and SPA-H for JIS G 3125. Issues • Conventional steel requires coating to prevent corrosion, leading to the heavy burden of repainting and other maintenance and management costs. • The use of steel in harmony with nature is desired. Issues • The use of COR-TEN is desired indoors. • There is a concern about initial rust in the shape of a flow or stream. Daigo Fukuryu Maru Exhibition Hall • COR-TEN in the aged state is provided. • The...
