Product Description

Product Description

Ordinary carbon structural steel, also known as ordinary carbon steel, has wide restrictions on carbon content, performance range and content of phosphorus, sulfur and other residual elements. In China and some countries, according to the guarantee conditions of delivery, it is divided into three categories: Class A steel (Class A steel) is steel with guaranteed mechanical properties. Class B steel (Class B steel) is a steel with guaranteed chemical composition. Special steel (Class C steel) is a kind of steel that guarantees both mechanical properties and chemical composition, and is often used to manufacture more important structural parts. At present, A3 steel (Class A No. 3 steel) with carbon content of about 0.20% is the most produced and used in China, mainly for engineering structures. Some carbon structural steels also add a small amount 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 steel, the chemical composition and properties of ordinary carbon structural steel have been adjusted, thus developing a series of professional steel for ordinary carbon structural steel (such as steel for bridges, buildings, reinforcement, pressure vessels, etc.).
