Product Description
Round steel is a kind of hollow cylindrical metal material, which is widely used in construction, machinery manufacturing, automobile manufacturing, energy, transportation and other industries.
Round steel is mainly made of carbon steel, alloy steel and tool steel.
Among them, carbon steel round steel refers to steel with carbon content within the range of 0.20% to 0.55%.
Carbon steel round steel is an economical and practical structural material with good weldability, plasticity and machinability.
Alloy steel round steel refers to the steel with a certain amount of alloying elements (chromium, manganese, cobalt, boron, molybdenum, vanadium, etc.), which can obtain higher strength, hardness, corrosion resistance and wear resistance.
Tool steel Round steel is a kind of high-speed tool steel material, which has the advantages of high hardness, high red hardness and wear resistance.
The production process of round steel is very diverse, including hot rolling, cold drawing and cold drawing.
Among them, the hot rolling production process refers to the steel material heated to a certain temperature, plastic deformation through rolling machinery and equipment, pressed into different specifications of the shape of steel.
The cold drawing process is the use of steel wire material for cold drawing, which can obtain a higher surface finish for the production of precision parts.
Cold drawing process is to draw steel in cold storage to obtain higher density, hardness and strength.
The wide application of round steel lies in its material characteristics and production process, which can meet the needs of different industries.
In construction projects, round steel is mainly used to build steel structure houses, large factories, Bridges, oil drilling platforms and oil mining equipment.
In the machinery manufacturing industry, round steel is mainly used to process gears, bearings, connecting rods, pins, shafts and other parts.
In the automobile manufacturing industry, round steel is mainly used to make auto parts, frames, suspension systems, guiding mechanisms and so on.
It is also widely used in energy, transportation and other industries.

Low carbon steel is easy to accept a variety of processing forging, welding and cutting, can manufacture chains, rivets, bolts, shafts and so on. Carbon content less than 0.25% carbon steel, because of its low strength and hardness and soft, it is also called soft steel. Including ordinary carbon structural steel and high-quality carbon structural steel. Low carbon steel is generally rolled into Angle steel, channel steel, I-steel, steel pipe, steel belt and steel plate, used to make a variety of building components, containers, boxes, furnace body and agricultural machinery. High-quality low carbon steel rolled into sheet, the production of car cab, engine hood and other deep drawing products; Made into bars, used to make mechanical parts with low strength requirements. Mild steel is limited in use due to its low strength. The strength of steel can be greatly improved by increasing the content of manganese in carbon steel and adding trace alloying elements such as vanadium, titanium and niobium. Using a mild steel bar, the manufacturer inserts the bar until the desired round steel pipe is formed. Welding with high frequency current. Once formed, pass the tube through a machine that corrects the deviation and cut the tube to the desired length. The mild steel pipe is then deburred and pressure tested. Finally, the tube receives hot dip galvanizing or surface painting. The ends of the mild steel pipe may be beveled and threaded with flanges. When producing lightweight vehicles, the automotive industry often uses mild steel pipes. These tubes may also be used for general framing or housing.
