Elvis Nickel Alloys is a well-known Houston, USA-based manufacturer and exporter of high-performance Duplex Steel S31803 Bolts of high quality. Recognized for unparalleled strength and resistance to abrasive weather conditions, our S31803 bolts are the best for heavy-duty use in industries. We carefully manufacture each bolt to exacting standards with high-end technology and high-quality raw materials. With a keen emphasis on product quality as well as customer satisfaction, we cater to varied industries such as marine, oil & gas, and structural engineering. Select Elvis Nickel Alloys for dependable Duplex Steel S31803 Bolts with incomparable performance, safety, and value for most demanding applications.
Duplex Steel S31803 Bolts are manufactured from about 22% chromium, 5-6% nickel, 3% molybdenum, and nitrogen content, which provides a dual-phase microstructure improving strength and corrosion resistance. These bolts possess high tensile strength (~620 MPa), yield strength (~450 MPa), and superior resistance to pitting, crevice corrosion, and stress corrosion cracking. They exhibit reliable performance over a broad range of temperatures and provide high fatigue resistance. Their composition provides superior toughness, weldability, and dimensional stability, and as such, they are perfectly suited for dynamic and heavy–duty industrial applications.

Duplex Steel S31803 Bolts find applications across industries where strength coupled with corrosion resistance are required. They are especially suitable for offshore oil rigs, marine equipment, and subsea equipment because they can operate in saltwater and high pressure conditions. They also find widespread applications in the chemical processing and pulp and paper industry in equipment handling acidic and alkaline chemicals. They are also used in heat exchangers, water treatment facilities, and heavy equipment. Their two-phase strength enables lower weight without sacrificing performance, which makes them a leading candidate for challenging structural uses.
