We offer These Duplex Steel S32205 Fasteners as per DIN, ISO, JIS or ANSI Standard.
Water resistance: Duplex steel S32205 has a balanced microstructure of austenite and ferrite phases, which provides excellent corrosion resistance, including stress corrosion cracking, pitting and crevice corrosion. This makes these fasteners suitable for use in complex environments such as marine and coastal applications.
Temperature range: S32205 duplex steel fasteners maintain their mechanical properties over various temperatures, from cryogenic to high temperature, enabling versatility under operating conditions.
Cost: While two-piece steel fasteners may cost more initially compared to conventional stainless steel, their high corrosion resistance and strength result in long-term cost savings by reducing maintenance, downtime and replacement costs. It can come from savings.
Fatigue Resistance: The dual S32205 design enhances fatigue resistance, making these fasteners ideal for use in applications subject to cyclic loads and vibration
Strength: S32205 duplex steel fasteners exhibit superior strength compared to austenitic stainless steel, leading to increased load-bearing capacity and better performance in construction applications
Duplex steel S32205 fasteners play a vital role across diverse industrial sectors, thanks to their exceptional properties. Widely utilized in industries such as chemical processing, oil and gas, marine, and offshore, these fasteners offer superior corrosion resistance and mechanical strength.
Oil and Gas Industry: Duplex steel S32205 fasteners are widely used in offshore and onshore oil and gas due to their resistance to sea water, acids and harsh chemicals; hence they are used in various industries like pipelines, sea under equipment, and functional workshops built.
Pulp and Paper Industry: Duplex steel S32205 fasteners find applications in the pulp and paper industry where corrosive chemicals are used during manufacturing.
Marine applications: Duplex steel S32205 fasteners are used in marine applications such as shipbuilding, offshore platforms and marine structures due to their corrosion resistance in the marine environment
Desalination equipment: Duplex steel S32205 fasteners are suitable in desalination plants where seawater is treated as fresh. The material’s corrosion resistance makes it ideal for seawater-corrosive environmental applications.
Chemical applications: In chemical corrosive control plants, duplex steel S32205 fasteners are preferred for their corrosion and pitting resistance. They are used in equipment such as reactors, heat exchangers, and storage tanks.
Understand application requirements: Identify the specific application for which you need the fastener. Consider load capacity, temperature, corrosion resistance, and environmental factors.
Corrosion Resistance: Duplex steel S32205 offers excellent corrosion resistance, especially in chloride-contaminated environments like seawater and chemical plants. If necessary, ensure that the packaging materials are treated appropriately or coated to maximize packaging.
Size and Dimensions: Based on the application specifications, determine the required fastener size, length, and thickness. Ensure fasteners meet the required standards and tolerances.
Grade Selection: Duplex Steel S32205 is a common grade known for its balanced combination of properties, including chloride stress corrosion crack resistance, high strength and good weldability, but others in your duplex stainless steel family, depending on your application Grades may need to be considered.
Compatibility: Check that duplex steel S32205 is suitable for your application. Duplex stainless steel provides excellent corrosion resistance and superior strength, making it suitable for various applications, including marine applications, chemical processing and oil and gas.
