Product Description
| MILD STEEL ROUND BAR |
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 0.04% to 0.20%.
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 0.04% to 0.20%.
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.
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.

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.
