Characteristics and Applications of Hot Rolled Pickled Steel
Hot rolled pickled steel is steel that has been processed by pickling, a method of removing scale and surface impurities from the steel. The pickling process involves immersing the steel in an acidic solution, typically hydrochloric acid or sulfuric acid, to remove the surface contaminants and oxide layer that forms on the steel when it is heated during the hot rolling process.
Characteristics
One of the main characteristics of hot rolled pickled steel is that it has a smooth, clean surface finish. The pickling process removes the scale and impurities from the surface of the steel, resulting in a surface that is free of defects and contaminants. This makes hot rolled pickled steel an ideal choice for applications where a smooth, clean surface is required, such as in the automotive industry, where it is used to make car body panels and other components.
Another characteristic of hot rolled pickled steel is that it has improved formability and weldability. The pickling process removes the oxide layer from the surface of the steel, which improves its ability to be formed and welded. This makes hot rolled pickled steel an ideal choice for applications that require the steel to be shaped or joined, such as in the construction industry, where it is used to make beams and other structural components.
In addition to its smooth surface finish and improved formability and weldability, hot rolled pickled steel also has good dimensional tolerances. The hot rolling process allows the steel to be rolled to very precise dimensions, and the pickling process helps to maintain these tolerances by removing any surface imperfections that may have been introduced during the hot rolling process.
Applications
There are several applications for hot rolled pickled steel. It is commonly used in the automotive industry to make car body panels and other components, as well as in the construction industry to make beams and other structural components. It is also used in the manufacture of appliances, such as refrigerators and washing machines, and in the production of pipes and tubes.
Hot rolled pickled steel is also used in the food and beverage industry, as it is resistant to corrosion and can withstand harsh cleaning and sterilization processes. It is commonly used to make equipment and machinery for the processing and packaging of food and drinks, as well as for the construction of storage tanks and other containers.
