Chemical reactions in steel structures:   (1) Chemical corrosion: Chemical corrosion is the result of direct chemical interaction between metals and surrounding media. It includes two forms of corrosion: gas corrosion and metal corrosion in non electrolytes.   (2) Electrochemical corrosion: Corrosion caused by the interaction between metals and electrolyte solutions such as acids, bases, and salts, known as electrochemical corrosion.   (3) General corrosion: This type of corrosion is evenly distributed on the entire inner and outer surfaces of the metal, causing the cross-section to continuously decrease and ultimately causing damage to the steel structural components under stress.   (4) Intergranular corrosion: This type of corrosion occurs inside the metal along the grain edges. It usually does not cause any changes in the metal's shape and often causes sudden damage to equipment or components. Zhaoqing Steel Structure Company   (5) Spot corrosion: This type…
