Duplex Steel S31803 / S32205 Fasteners

ASME SA194 DSS S31803 Fastener, Duplex Steel UNS S32205 Bolts, Duplex 2205 Industrial Fasteners Supplier in India.

Duplex Steel S31803 and S32205 are extensively utilized in industries that demand materials possessing superior strength and resistance to corrosion. These alloys belong to the family of duplex stainless steels, which perform better in harsh conditions by combining the qualities of ferritic and austenitic stainless steels. The first iteration of duplex stainless steel is called UNS S31803, or Duplex Steel S31803. About 22% chromium, 5% nickel, and 3% molybdenum are present. A good balance between strength, corrosion resistance, and weldability is offered by this composition. Because of its exceptional resistance to pitting and crevice corrosion, S31803 finds application in both the chemical processing and maritime industries. It is frequently used for fasteners that require high strength and resistance to stress corrosion cracking, such as bolts, nuts, and washers.
These duplex steels are highly valued for their exceptional mechanical qualities and longevity when used to make fasteners. They are made to withstand severe conditions and huge weights without breaking down. They are a dependable option for demanding applications because of their resistance to corrosion and stress corrosion cracking, which guarantees a longer service life and lower maintenance costs. Duplex steel fasteners offer strength and resistance for pressure vessels, pipelines, and structural components, assuring efficiency and safety in a range of industrial situations.

An improved form of S31803 is Duplex Steel S32205, also known as UNS S32205. It has significantly greater concentrations of nickel (5–6%), molybdenum (3%), and chromium (around 22%). These improvements raise its tensile strength and strengthen its resistance to corrosion. S32205 is preferred in more demanding applications including the oil and gas sector, chemical processing, and seawater handling because it performs better in severe environments, especially those with higher chloride concentrations.
