Carbon steel rod is a type of low carbon steel widely used in the petroleum, chemical and boiler industries. This material has good mechanical properties. Round bars are divided into three types: hot rolled, forged and cold drawn. Hot rolled round bars are available in sizes from 5.5-250 mm. Among them: 5.5-25 mm small round steel is mostly supplied in bundles and straight bars, often used as steel bars, bolts and various mechanical parts; round bars larger than 25 mm are mainly used to manufacture mechanical parts, steel pipe gaps of seamless steel pipes, etc.

A105 carbon steel is a kind of carbon structural steel, with good weldability, machinability, corrosion resistance and high temperature stability, widely used in petroleum, electric power and other industries.

AISI 4140 carbon steel rod is a low alloy steel rod containing chromium, molybdenum and manganese.AISI 4140 is an excellent material choice for a wide range of industries due to its toughness, high fatigue strength, wear resistance and impact resistance. The hardness of AISI 4140 is hrc28~32 and the hardness of AISI 4140 after annealing is hrc22~28. The chemical composition of AISI 4140 contains 0.38~0.43% carbon, 0.17~0.37% silicon, 0.50~0.80% manganese, 0.15~0.35% sulfur, 0.15~0.35% phosphorus, 1.20~1.60% chromium, and 0.40~0.60% molybdenum.

AISI 1018 Carbon steel round rods are made of carbon steel and consist of carbon, chromium, manganese, molybdenum, phosphorus, sulfur and silicon. Carbon steel SAE1018 rods are commonly used in shafts, pins, rods, spindles, sprocket assemblies and a wide range of parts.

The A36 carbon steel bar is a carbon structural steel mainly used in the manufacture of welded and bolted metal structures for industrial and civil buildings as well as bridge construction.
