Hex Shaft Steel Hex Tubing Processing Inside

1. Excellent Torque Transmission Efficiency

• Eliminates rotational slip between the shaft and connected components, ensuring 100% torque transfer even under heavy loads (e.g., in industrial mixer drives or conveyor systems).

• Distributes torque evenly across six flat sides, reducing stress concentration (a common issue with round shafts relying on single keyways). It can handle 15–30% higher torque than round shafts of the same material and cross-sectional area.

2. High Mechanical Strength & Stability

• Material-Driven Durability: Typically made from high-performance steels such as 45# medium carbon steel, 40Cr alloy steel, or 304 stainless steel. For example:

• Quenched-tempered 45# Hex Shaft Steel offers a minimum yield strength of 355MPa and tensile strength of 600MPa, resisting bending and torsion in heavy-duty machinery.

• 40Cr alloy steel variants provide even higher strength (yield strength ≥785MPa) and impact resistance, suitable for automotive steering shafts or construction equipment.

• Structural Rigidity: The hexagonal shape enhances anti-bending and anti-torsion rigidity, maintaining dimensional stability under long-term loads (e.g., as drive shafts in gearboxes).

3. Precision Dimensional Accuracy

• Dimensional tolerance for key parameters (e.g., side length, flatness) is controlled within ±0.05mm, ensuring seamless assembly with mating parts (no need for time-consuming on-site adjustments).

• Surface finish reaches Ra ≤0.8μm after grinding, reducing friction between the shaft and bearings/couplings, and minimizing wear during operation.

4. Easy Installation & Maintenance

• Tool-Friendly Design: The hexagonal sides allow easy gripping with standard tools (e.g., wrenches), simplifying installation and disassembly—no need for specialized fixtures.

• No Extra Locking Components: Unlike round shafts (which require keys, set screws, or pins to prevent rotation), the hexagonal profile locks directly with mating parts, reducing assembly steps and eliminating the risk of loose fasteners over time.

5. Versatile Material Options

• Carbon Steel (45#, A36): Cost-effective for general industrial use (e.g., machinery frames, low-load shafts).

• Alloy Steel (40Cr, SCM440): For high-stress, wear-prone scenarios (e.g., automotive differential shafts).

• Stainless Steel (304, 316): Offers excellent corrosion resistance for harsh environments (e.g., marine equipment, food processing machinery).

Special-shaped steel pipe

Shaped seamless steel pipe is widely used Used for various structural parts, tools and mechanical parts. Compared with the circular tube, the shaped tube generally has a larger moment of inertia and cross-section modulus, and has a larger Anti-bending, anti-torsion, can greatly reduce the weight of the structure, save steel.

Concrete pump pipe

Pump pipe is divided into two types: automobile pump pipe and ground pump pipe, automobile pump pipe includes boom pipe, hinged elbow, Reducer and bend pipe, wherein cast steel and straight pipe material 45mn2. The ground pump pipe is ordinary 20# carbon steel, which is processed by fluid pipe or straight seam pipe.

Welded steel pipe

According to the different welding methods, welded steel pipes can be divided into arc welded pipes, high-frequency resistance welded pipes or low-frequency resistance welded pipes. Gas welded pipe, furnace welded pipe, Bondi pipe. According to the shape of the weld, it can be divided into straight welded pipe and spiral welded pipe.

Rectangular steel pipe

Rectangular pipe is a hollow square cross-section of light thin-wall steel pipe, also known as steel cooling curved profile. It is made of Q235 hot rolled or cold rolled strip or coil as the base material by cold bending processing and then high frequency welding made of square section shape and size of the section steel.
