Product Description

About products

 Ordinary carbon structural steel, also known as ordinary carbon steel, has wide restrictions on carbon content, performance range, and the content of phosphorus, sulfur, and other residual elements. In China and some countries, there are three types of steel according to the guarantee conditions for delivery: Class A steel (Class A steel) is a steel with guaranteed mechanical properties. Class B steel (Class B steel) is a steel that ensures chemical composition. Special steel (Class C steel) is a steel that ensures both mechanical properties and chemical composition, and is commonly used to manufacture more important structural components. Currently, the most widely produced and used steel in China is A3 steel (Class A No. 3 steel) with a carbon content of about 0.20%, mainly used for engineering structures. Some carbon structural steels also add trace amounts of aluminum or niobium (or other carbide forming elements) to form nitride or carbide particles to limit grain growth, strengthen the steel, and save steel. In China and some countries, in order to meet the special requirements of professional steels, the chemical composition and properties of ordinary carbon structural steels have been adjusted, resulting in the development of a series of professional steels for ordinary carbon structural steels (such as steels for bridges, buildings, reinforcement, pressure vessels, etc.)
