We are a full steel product mix including stainless steel, carbon steel, galvanized steel, aluminum and specialized alloy products having a registered capital of 51.17 million yuan and based in the Jinan City, Shandong Province. We are near the large domestic steel manufacturers such as the Shandong Iron and Steel as well as the Tangshan Iron and Steel. This strategic position will enable us to provide high quality products such as the Hot Rolled Alloy Steel Round Bar which is used in the demanding engineering work.

What Are Hot Rolled Alloy Steel Round Bars?

Hot rolled alloy steels round bars are long, hollow products of uniform cross-section, which is circular in shape and produced in a high-temperature rolling process. The process of manufacturing begins with heating of alloy steel billets in furnace at a temperature of approximately 1, 200degC, which is higher than the recrystallization temperature of the material. The hot billet then undergoes a series of rotating rolls in a rolling mill which is a series of rotating rolls which decreases the diameter of the billet until the desired requirements are achieved. This high temperature working process refines the grain structure, eliminates internal pore and improves all the mechanical properties of the steel. The outcome is a high strength, durable, tough and great ductile round bar that can withstand the extreme working conditions.

Superior Properties and Material Advantages

The mechanical properties of the hot rolled alloy steel round bars are excellent due to the blending of the alloying elements. Carbon steel is enriched with other elements such as chromium, molybdenum, nickel and vanadium such that the performance characteristics are enhanced significantly. These bars come in various grades and provide:

High Tensile and Yield Strength: Can support a heavy weight without being permanently deformed.

Excellent Toughness and Wear Resistance: Resist cracking and frictional wear on the surface.

Fatigue Resistance: The material is stress cycle resistant and this is appropriate in dynamic use.

Hardness and Hardenability: Capability of attaining the intended hardness via heat treatment which include quenching and tempering.

Popular grades of alloy steels like 4140 and 4340 has been known to be well balanced in terms of strength and toughness and hence, are utilized in critical parts in all industries.

Wide Range of Industrial Applications

The hot rolled alloy steel round bars cannot be ignored in heavy industries because they have high strength-to-weight ratio and can be used over a long time. Key applications include:

Automotive and Transportation: required high stress components of a drive axle, transmission gears, crankshaft, steering knuckle, and part of the suspension that is continuously vibrated and torques.

Heavy Machinery and Construction Equipment: Hydraulic cylinders, shafts, track pins, rollers, structural supporting structures in excavators, bulldozers, and cranes: Impact and abrasion resistance are important.

Aerospace and Defense: Applicable in landing gear, engine mounting and structural fittings where extreme loads are required to be very high integrity and high reliability.

Oil and Gas Industry: Drill collars, valve parts, down hole tools and pumping equipment are machined items that have to resist high pressure, corrosive conditions, and extreme temperatures.

General Engineering and Manufacturing: This is applied in forging, machining of custom parts, tool holders, spindles and fasteners of a certain size and material requirements.
