Duplex Steel 2205 Stud Bolts are used in a variety of high-strength, corrosion-resistant applications. The bolts are used in chemical processing, oil and gas, marine, and power generation applications. The bolts exhibit better resistance to pitting, crevice corrosion, and stress corrosion cracking and, therefore, can be used where the environment is harsh, e.g., seawater, acidic, and elevated temperature. Common applications include heat exchangers, pressure vessels, piping, and structural members. Duplex Steel 2205’s outstanding mechanical properties ensure strength and reliability in extreme conditions, providing a long-lasting, cost-saving fastening solution across a range of industrial applications.
Duplex Steel 2205 Stud Bolts are properly packed to prevent any damage during shipping and ensure safe delivery. They are usually packed in sturdy boxes or wooden crates with suitable cushioning material to protect them. Before they are dispatched, each stud bolt is put through rigorous testing like visual examination, measurement checks, tensile strength tests, and corrosion resistance tests to make sure it is up to the industry standards. This provides assurance of fasteners’ quality, performance, and reliability under demanding applications and offers the customers dependable products to use in their construction.
