Duplex Steel Stud Bolts are manufactured from a combination of stainless steel and nickel alloys with a normal composition of 22% chromium, 5% nickel, 3% molybdenum, and nitrogen. Such a composition provides excellent resistance to pitting, stress corrosion cracking, and chloride-induced corrosion and is hence suitable for hostile environments. Mechanical properties include 450 MPa yield strength, tensile strength of 620 MPa, and elongation of 25%. The stud bolts have resistance to fatigue, wear, and high temperatures with the ability to ensure durability and reliability for harsh applications like marine, chemical, and oil & gas

Duplex Steel Stud Bolts are highly appreciated in high-strength and corrosion-resistant applications. They have excellent resistance to pitting and stress corrosion cracking and are ideal for severe conditions, such as chemical processing, marine, oil & gas, and offshore industries. They are applied in pressure vessels, heat exchangers, desalination plants, and structural parts. They find applications in high-pressure and high-temperature applications where reliability and strength are the prime concerns. Duplex Steel Stud Bolts ensure secure fastening in challenging conditions, giving them long performance lifespan under harsh conditions like saltwater, chemicals, and low/hot temperatures.
Duplex Steel Stud Bolts are packaged with the highest level of care to ensure safe transportation, with each bolt wrapped individually to avoid damage, moisture, and contamination. The packaging is designed to sustain rough handling during shipment, ensuring product integrity. The stud bolts undergo rigorous testing before shipment, including dimensional inspection, tensile strength test, and corrosion resistance test. These inspections ensure each batch has the best quality, providing maximum performance and reliability in harsh applications in industries like marine, oil & gas, and chemical processing.
