Product Description
C276 Introduction
Super alloys or high performance alloys are available in a variety of shapes and contain elements in different combinations to obtain a specific result. These alloys are of three types that include iron-based, cobalt-based and nickel-based alloys. The ickel-based and cobalt-based super alloys are available as cast or wrought based alloys according to composition and application.Super alloys have good oxidation and creep resistance and can be strengthened by precipitation hardening, solid-solution hardening and work hardening methods. They can also function under high mechanical stress and high temperatures and also in places that require high surface stability. HASTELLOY(r) C276 is a wrought corrosion-resistant alloy that resists the development of grain boundary precipitates that degrade corrosion resistance.
The following datasheet provides an overview of HASTELLOY(r) C276.
C276 Forging Threaded Hex Head or Flush Bushing Introduction
Internal and external thread joints, commonly known as internal and external threads, are straight-through transfer fittings with internal threads on one end and external threads on the other. They are divided into two categories: equal diameter and variable diameter. They mainly realize the transfer and adaptation of pipeline thread specifications and interface types. They are widely used in plumbing, pneumatic, hydraulic, chemical, instrumentation and other piping systems. Products are commonly made of brass, 304/316 stainless steel, malleable steel, and forged carbon steel, and are suitable for different pressures and media: brass is mostly used for household water supply and drainage, and low-pressure gas; stainless steel is resistant to acid and alkali corrosion and is suitable for high-pressure working conditions in food and chemical industries; malleable steel and carbon steel are mostly used for fire protection, steam, oil and gas pipelines. Common threads include 55° parallel G thread, 55° tapered pipe R/Rc thread, 60° American standard NPT tapered thread and special metric M thread for pressure gauges. There are differences in the sealing methods of different threads. Tapered threads rely on thread surface sealing, and parallel threads need to be equipped with sealing gaskets to prevent leakage. There is a hexagonal clamping position in the middle of the joint, which facilitates the disassembly and assembly of the wrench. The integral molding is stable in pressure bearing and takes up little installation space. Complying with national standards such as GB/T3287 and GB/T14383, the tapered thread can be wrapped with raw material tape to
enhance sealing during installation. Only the hexagonal part is clamped during operation to avoid cracking of the thread slide wire. Compared with the split union, the integrated inner and outer wire has a simple structure and lower cost. It is suitable for fixed pipelines that do not require frequent disassembly. It is the most basic and most used transfer accessory in the pipeline system.

Product processing
C276 Forging Threaded Hex Head or Flush Bushing Product packaging
1.Raw material cutting
The raw materials used are brass, stainless steel and carbon steel rods. The products are cut to the specified length by a CNC sawing machine according to the product specifications, and the length tolerance of the blanks is controlled. After the forging type workpieces are cut, they undergo heating treatment to prepare for forging.
2. Rough Casting
It is divided into two processes. The hexagonal clamping position and the main body of the forged part are formed through high-temperature forging and integration at one time. The structure is dense and has stronger pressure-bearing capacity. The bar material turned parts directly enter the lathe for rough processing, removing the excess material on the surface, and rough-cutting out the basic contours of the outer circle, steps and end face.
3.Precision turning processing
After rough processing, the parts are further machined for fine finishing. The end face,
positioning step and hexagonal shape are precisely refined. The coaxiality and flatness are strictly controlled. The thread
processing allowance is reserved, the processing steps are eliminated, and the sealing end face is ensured to be flat.

4. Thread processing and deburring
The internal threads are machined using taps, while the external threads are cut by thread turning tools.
The tooth profiles strictly match those of standards such as G, NPT, and R. After the processing is completed, the inner and outer holes as well as the edges and corners of the threads are cleaned to remove any burrs, to prevent scratches on the sealing surfaces during assembly.

5. Surface anti-corrosion treatment
The brass parts are polished and then electroplated with nickel-chromium to prevent rust; the carbon steel and martensitic steel parts are hot-dip galvanized to enhance their rust resistance; the stainless steel workpieces undergo passivation treatment to improve their resistance to acid and alkali corrosion.
6. Quality inspection of finished products
6. Quality inspection of finished products
The thread accuracy is inspected using thread gauge sets, and the external dimensions are verified with calipers. Sampling is conducted for water pressure resistance tests to detect cracks, sand holes, leaks, etc., and non-conforming products are eliminated.
7. Clean packaging is stored in the warehouse.
Qualified products are cleaned to remove processing oil stains. The threaded parts are covered with plastic protective sleeves. They are classified and packaged according to specifications, with model and pressure grade marked. They are uniformly stored in the warehouse. The entire process strictly controls the accuracy and sealing performance. It is fully formed without weld seams, and is suitable for various pressure-bearing conditions of water heating, hydraulic, chemical and other types of pipelines.
