Elvis Nickel Alloys is a well-known manufacturer and exporter of Duplex Steel Bolts in Houston, USA, providing superior fastening solutions to industrial and structural uses. Famous for their exceptional resistance against corrosion, stress, and excessive mechanical loads, our Duplex Steel Bolts come in various sizes and standards. We have rigorous quality checks and testing protocols to provide the durability and reliability of each bolt. With a broad industry presence in oil & gas, marine, petrochemical, and construction, Elvis Nickel Alloys is your one–stop destination for high-strength, corrosion-free duplex steel fastening systems.
Duplex Steel Bolts consist of a two-phase microstructure with around 22% chromium, 5-6% nickel, 3% molybdenum, and nitrogen. These components offer improved strength, with tensile strength of up to 620 MPa and yield strength of approximately 450 MPa. Their elevated PREN (Pitting Resistance Equivalent Number) provides extraordinary resistance to pitting and crevice corrosion. Duplex bolts also exhibit exceptional fatigue resistance and structural integrity at high temperatures. The ferrite-austenite matrix offers excellent weldability, and these bolts are thus the first choice for pressure-bearing and structural assemblies in aggressive environments.

Duplex Steel Bolts are designed for application in high-stress environments where strength, corrosion resistance, and dependability are paramount. They find frequent application in offshore drilling platforms, subsea piping systems, and ship construction, where exposure to saltwater is involved. They also find extensive application in refineries, chemical plants, and pressure vessels because they can withstand corrosive chemicals and high pressures. In structural engineering, they exhibit high load-bearing capacity in bridges, towers, and industrial structures. Their duplex structure suits mechanical strength and corrosion resistance, providing long-term performance in aggressive industrial environments.
