Product Description
Alloy 718 Introduction.
Alloy 718/2.4668 is a nickel-chromium-iron alloy with niobium and molybdenum and low contained aluminum and tnum. Excellent mechanical properties in lower temperatures. Excellent corrosion resistance at high and low temperatures
Inconel 718 is a nickel-based super alloy that is well suited for applications requiring high strength in temperature ranges from cryogenic up to 1400°F. Inconel 718 also exhibits excellent tensile and impact strength.

Threaded Hex Head Bushing Introduction
1. Precision Threaded Structure: The threaded hex head bushing is designed with standard precision internal or external threads, processed by high-precision thread cutting and rolling technology. The thread tooth shape is complete, the pitch is uniform, and the fit clearance is strictly controlled, which can realize smooth screwing-in and reliable locking connection with matching threaded pipes and equipment parts.
2. Dual-Function Hex Head Design: Integrated with a standard hexagonal outer head structure, the bushing combines threaded connection and tool fastening functions. The hexagonal head provides stable force-bearing points for wrenches and pneumatic tools, effectively avoiding thread slipping and loose connection during installation and maintenance, greatly improving assembly accuracy and operational efficiency.
3. High Structural Firmness & Pressure Resistance: Adopting integral forming and fine machining process, the threaded hex head bushing has uniform internal stress and strong overall rigidity. It can stably bear high hydraulic pressure, mechanical axial load and torsional force, will not produce thread deformation, tripping or breakage in long-term high-load operation, and ensures stable system operation.
4. Reliable Sealing & Leak-Proof Performance: The precise matching thread structure cooperates with flat or tapered sealing surfaceto form a tight connecting gap. It can effectively prevent leakage of liquid, gas and other media in pipelineand hydraulic systems, with excellent sealing performance, which is suitable for closed-loop transmission and pressurized working scenarios.
5. Durable Wear & Corrosion Resistance: Made of high-quality metal materials such as carbon steel and stainless steel, with surface anti-rust, oxidation and wear-resistant treatment. The threaded surface is smooth and burr-free, which reduces friction loss during repeated disassembly and assembly, and resists chemical corrosion and atmospheric erosion, significantly extending the service life of the bushing.
6. Versatile Industrial Compatibility: This threaded hex head bushing conforms to international industrial standard
specifications, compatible with most standard threaded pipes, valves, hydraulic components and mechanical fasteners. It is widely used in hydraulic systems, mechanical equipment, pipeline engineering, automotive and marine industrial fields for connection, fixing and transition assembly.

718 Threaded Hex Head Bushing Produce Processing
1. Raw Material Inspection & Cutting:
High-quality standard 718 alloy steel is selected as the core raw material. We conduct rigorous inspection on chemical
composition, mechanical hardness and surface quality, and verify material certificates to meet industrial standards. Qualified steel bars are precisely cut into fixed-size blanks according to product specifications for subsequent formal production.

2. Hot Forging & Structural Forming:
The pre-cut 718 blanks are heated to professional forging temperature and integrally forged by dedicated equipment. This process refines the internal metal grain structure, removes internal pores and impurities, and greatly improves the product’s density, toughness and structural stability, effectively preventing cracking and deformation under high-pressure working conditions.
3. Professional Heat Treatment:
Post-forging blanks undergo standardized quenching and tempering heat treatment. The process thoroughly eliminates internal forging stress, homogenizes material hardness, and upgrades the product’s tensile strength, pressure resistance and fatigue resistance. It enables the 718 bushing to adapt to harsh high-temperature and high-load industrial working environments.

4. CNC Precision Machining & Threading:
Advanced CNC lathes are used for precision processing of outer diameter, inner hole and hexagonal head to ensure accurate dimensions, flat hexagonal surfaces and qualified tolerance range. Standard internal and external threads are finely turned and rolled with calibrated pitch and tooth profile, ensuring burr-free thread surfaces and smooth, tight assembly with matching fittings.

5. Finishing & Strict Quality Inspection:
All residual burrs, sharp edges and processing scraps are completely removed, and the product surface is polished for a smooth finish. Each finished product undergoes full inspection including dimensional accuracy, thread precision, hardness test, surface defect detection and pressure resistance sampling, with all unqualified products strictly rejected.
