Alloy C-276 (UNS N10276 / W.Nr. 2.4819) Hex Bolt

Alloy C-276 hex bolts, also referred to as UNS N10276 / W.Nr. 2.4819 alloy hexagonal head bolts, are threaded fasteners designed to be used with a nut or inserted into a tapped hole.

These bolts come in two styles: fully threaded or partially threaded, with the latter featuring a smooth section of the shank. Hex bolts are widely used across various industries, particularly in machinery and construction projects.

Available in different types, sizes and finishes, C-276 hex bolt offers versatility and allow for the selection of the most suitable option for specific applications. Their distinctive six-sided head also leads to them being called hex head bolts or hexagon bolts.

UNS N10276 Alloy C-276 Hex Bolt Production Process

The production process of UNS N10276 Alloy C-276 hex bolts involves several key steps to ensure precision, quality, and durability. Here’s a general outline of the process:

1. Material Selection and Preparation
The alloy C-276 is supplied in bar form, which is cut to the required lengths for bolt production.

2. Forming the Hex Head
Hot Forging or Cold Forging: The cut metal is heated (hot forging) or kept at room temperature (cold forging) to form the hexagonal head of the bolt.


3. Threading
Rolling or Cutting Threads: Threads are created on the shaft of the bolt by either rolling (deforming the surface without material loss) or cutting (removing material to form threads).

4. Heat Treatment

5. Surface Finishing

6. Inspection and Testing
Dimensional Check: The bolts are inspected for correct dimensions, thread pitch, and overall quality.
Non-destructive Testing (NDT): Various tests (e.g., ultrasonic or magnetic particle inspection) are performed to check for internal defects.
Mechanical Testing: Hardness, tensile strength, and impact tests are conducted to ensure the bolts meet industry standards.

7. Packaging

This process ensures that UNS N10276 alloy C-276 hex bolts meet the high standards required for applications in harsh, corrosive environments.

UNS N10276 Alloy C-276 Hex Bolt Standards and Markings

Standards:

We manufacture C-276 hex bolts strictly according to recognised standards:

  • DIN 931

UNS N10276 Alloy C-276 Hex Bolts: The Ultimate Guide

When you choose to buy UNS N10276 Alloy C-276 Hex Bolt, there have some important points we need to know before we get started.

So enjoy the read…

What are UNS N10276 Alloy C-276 Hex Bolts?

Alloy C-276 hex bolts, also referred to as UNS N10276 / W.Nr. 2.4819 alloy hexagonal head bolts, are threaded fasteners designed to be used with a nut or inserted into a tapped hole. It is the one of the top products of nickel alloy fasteners.

These bolts come in two styles: fully threaded or partially threaded, with the latter featuring a smooth section of the shank. Hex bolts are widely used across various industries, particularly in machinery and construction projects.

Available in different types, sizes and finishes, C-276 hex bolt offers versatility and allow for the selection of the most suitable option for specific applications. Their distinctive six-sided head also leads to them being called hex head bolts or hexagon bolts.

How do UNS N10276 Alloy C-276 Hex Bolts work?

C-276 alloy hex bolts are versatile fasteners that can be used with pre-tapped holes or paired with nuts, depending on the application. They can be tightened or loosened using various tools such as hex wrenches, socket sets, spanners, hex keys, or ratchet spanners.

The hexagonal head design allows for easy gripping from multiple angles, making installation and removal simple. This shape also ensures that the bolts can be easily tightened or loosened, even after they are in place.

Features of UNS N10276 Alloy C-276 Hex Bolts

Alloy C-276 (UNS N10276 / W.Nr. 2.4819) hex bolt is known for its corrosion resistance in a wide range of aggressive media.

The high molybdenum content imparts resistance to localized corrosion such as pitting.

The low carbon minimizes carbide precipitation during welding to maintain resistance to intergranular attack in heat-affected zones of welded joints. It is used in chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment and the recovery of “sour” natural gas.

Applications in air pollution control include stack liners, ducts, dampers, scrubbers, stack-gas re-heaters, fans and fan housings. In chemical processing, the alloy hex bolt is used for components including heat exchangers, reaction vessels, evaporators and transfer piping.
