Duplex steel hex bolts are fasteners made from duplex stainless steel, which is a type of stainless steel that contains a balanced microstructure of austenite and ferrite phases. This composition gives duplex steel enhanced mechanical and corrosion-resistant properties compared to other types of stainless steel. Hex bolts, also known as hexagon bolts or hex head bolts, are threaded fasteners with a hexagonal head and a threaded shaft. They are commonly used in various applications where a secure and robust fastening is required.

When you require robust and corrosion-resistant fastening solutions, look no further than our company, your dependable Duplex Steel Hex Bolts Supplier.
As an experienced Duplex Steel Hex Bolts Manufacturer, we specialize in crafting high-quality hex bolts from Duplex steel, ensuring exceptional durability and resistance to harsh environments for various industrial applications.
The use of duplex steel for hex bolts offers several advantages. The duplex structure provides high strength, making these bolts suitable for applications that require superior mechanical properties. Additionally, duplex steel has excellent resistance to corrosion, including resistance to pitting, crevice corrosion, and stress corrosion cracking.
Due to their excellent corrosion resistance, duplex steel hex bolts are widely used in offshore oil rigs, marine vessels, and other saltwater environments. These bolts are used in desalination plants, where high corrosion resistance is required due to the presence of saltwater. Duplex steel hex bolts also find applications in the pulp and paper industry, where they are exposed to corrosive chemicals and high temperatures. When selecting duplex steel hex bolts, it is essential to consider factors such as bolt size, thread pitch, length, and other specific requirements based on the application.
Are Duplex Steel Hex Bolts reusable?
Duplex Steel Hex Bolts can be reusable, depending on their condition after removal. The bolts can be reused if they are in good condition, free from damage or deformities, and meet the required specifications. It is important to carefully inspect the bolts before reuse to ensure their integrity and performance.
Can Duplex Steel Hex Bolts be used in high-temperature applications?
Yes, Duplex Steel Hex Bolts are suitable for high-temperature applications. Duplex stainless steel exhibits good thermal stability & can maintain its mechanical properties at elevated temperatures. It is essential to consider the specific grade of Duplex stainless steel and its temperature limits to ensure it meets the requirements of the intended application.
Are Duplex Steel Hex Bolts available in different sizes and lengths?
Yes, Duplex Steel Hex Bolts are available in various sizes and lengths to accommodate application requirements. The bolts diameter typically specifies the sizes, while the length can vary based on the project’s specific needs. It is important to select the appropriate size & length of the Hex Bolt to ensure a proper fit and effective fastening.
