Properties and carbon content of carbon steel elbows

　　The higher the carbon content, the higher the hardness and strength, but the lower the plasticity. First, the mechanical properties depend on the carbon content in the steel, which usually does not increase a lot of alloy elements, sometimes referred to as plain carbon steel or carbon steel. Carbon steel, also known as carbon steel, refers to iron-carbon alloys with carbon content less than 2%.

　　Carbon steel can be divided into three types according to its use: carbon structural steel, carbon tool steel and free cutting structural steel. Carbon structural steel can be divided into construction structural steel and machine-made structural steel. According to carbon content, carbon steel can be divided into low carbon steel (C < 0.25%), medium carbon steel (C 0.25% - 0.6%) and high carbon steel (C > 0.6%). According to the mixture of phosphorus and sulphur, carbon steel can be divided into ordinary carbon steel (high phosphorus and sulphur content), high quality carbon steel (low phosphorus and sulphur content) and high quality steel (low phosphorus and sulphur content) usually the higher carbon content, the harder carbon steel is. The higher the strength, the higher the plasticity.

　　The use of ASTM A234 Wpb Special Carbon Steel 90 Long Redius Elbow and device use: carbon steel elbow is used for the connection of pipeline bend. Connect two pipes with the same nominal diameter to make the pipeline turn as the viewpoint. Carbon steel elbow can be said to cover the use of all walks of life throughout the country, from small families to large companies. Each carbon steel elbow has its own interests and uses.
