Low Temperature Carbon Steel is a mixture of steel and carbon content up to 2.1% by weight. Carbon steel pipes come in two distinguished categories viz. Low-carbon Steel and High Carbon Steel. Further Low-Carbon steel also come in two types Mild and high-tensile carbon steels.
Low Temperature carbon steel also known as Mild or Plain-carbon steel is the most widely used form of steel as it is relatively low. It also provides good mechanical properties for use in many applications. The carbon content in mild steel is 0.05%-0.25%, which makes it malleable and ductile. Mild steel Pipes have relatively low tensile strength. The surface hardness of this steel can be increased via. Carburizing. Lesser carbon content in these steels makes cold-forming easy on low-carbon steels. High-tensile steel pipes also belong to the low-carbon steel group, which lie at the lower end of the medium-carbon content. Other elements like molybdenum, manganese, silicon, nickel, vanadium, and chromium are added to improve tensile strength of low-carbon steel pipes. Manganese is generally added to carbon steel pipes to improve their hardenability.
