High Quality Carbon Structural Steel Rod En C22e S235 ASTM 1020 1035 Cold Drawn Steel Round Bar

Round steel is a common steel material with a round shape and is usually used to manufacture various mechanical parts, building structures, automobile parts, etc. The manufacturing process of round steel is relatively simple and the cost is low, so it is widely used in the industrial field.

Classification by process

Round steel is divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled round steel are 5.5-250 mm. Among them: small round steel of 5.5-25 mm is mostly supplied in straight strips and bundles, and is commonly used as steel bars, bolts and various mechanical parts; round steel larger than 25 mm is mainly used to manufacture mechanical parts and seamless steel pipe blanks. wait.

Classification by chemical composition

Carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel according to its chemical composition (i.e. carbon content).

Classification by steel quality

According to the quality of steel, it can be divided into ordinary carbon steel and high-quality carbon steel.

Classified by use

According to use, it can be divided into carbon structural steel and carbon tool steel.
Carbon tool steel has a carbon content between 0.65 and 1.35%. It can obtain high hardness and high wear resistance after heat treatment. It is mainly used to manufacture various tools, cutting tools, molds and measuring tools (see tool steel).


Round steel is widely used in construction, machinery, automobiles, ships, aerospace and other fields. In the construction field, round steel can be used to make beams, columns, plates, etc. of reinforced concrete structures; in the mechanical field, round steel can be used to make various bearings, gears, connecting rods and other mechanical parts; in the automotive field, round steel can Used to manufacture wheels, axles, brackets and other parts; in the fields of shipbuilding and aerospace, round steel also has its unique application value.
