Hot Forged Steel Bar

Product Range of Hot Forged Steel Bar

At CUMIC Steel, our forged bars enable us to serve our customers in providing a variety of applications, such as bearings, transmissions, heavy engineering, hydraulics, etc. Our product range includes forged round bars, forged square bars, forged blocks, forged rings that are in sync with different commercial grades and international standards. The dimension tolerances of the forged steel bars can also be tailored to your specific needs.

Development of Forged Steel Round Bar

With the development trend of high strength and lightweight parts, the forging industry to pursue high material utilization, high precision, high efficiency, low energy consumption, low cost and other goals. The development of forged steel round bar is inseparable from the evaluation and application technology development. Hot forging steel for easy cutting, non-quenching, cold forging steel to simplify heat treatment is to reduce the cost of the parts process, improve production efficiency and energy saving, the main material technology; micro-alloying is to improve the toughness of parts and process performance, to obtain high-performance, low-cost forgings effective means.

The Difference Between Forged Steel Rod and Other Steel Bars

1.Appearance 

Forged steel rod: light garden, no grain without ribs; 

Other steel bars: surface appearance has a carved pattern or rib. 

This causes the bonding force of round steel and concrete is small, while other steel bars and concrete bonding force is large. 

2.Different ingredients

Forged steel rod (primary steel) belongs to the ordinary low carbon steel, other steel bars are mostly alloy steel. 

3.Strength 

Forged steel rod strength is low, while other steel strength is high.That is, the diameter of the same size of the round steel and other steel bars, compared to other steel bars, forged steel rod can withstand the tensile force is smaller than other steel bars, but the plasticity of forged steel rod than other steel bars, that is, forged steel rod before being pulled off a large deformation, while other steel bars before being pulled off the deformation is much smaller.

Details of Forged Steel Products

Forged round is a round steel forged by process requirements. Specifications domestic general production can reach 1500mm diameter. Forged steel products are suitable for small parts or shaped steel processing.

Round steel is a solid long steel with a circular cross-section. Its specifications are expressed in millimeters of diameter, such as " 50 " that is, the diameter of 50 mm round steel.

Round steel is divided into three types: hot-rolled, forged and cold-drawn. Hot-rolled round steel specifications for 5.5-250 mm. Among them: 5.5-25 mm of small round steel mostly supplied in bundles of straight bars, commonly used as reinforcement, bolts and various mechanical parts; more than 25 mm of round steel, mainly used in the manufacture of mechanical parts or for seamless steel billets.
