Jyoti Steels is a trustworthy and well-established Duplex Steel S32205 Nuts manufacturer and supplier from Mumbai, India. Jyoti Steels is dedicated to quality and performance and supplies high-quality fasteners that conform to international standards and are used in critical industrial applications. Their S32205 nuts are famous for their exceptional strength, corrosion resistance, and durability and are best suited for tough and harsh environments. Supported by state-of-the-art manufacturing plants and technical know-how, Jyoti Steels provides these high-quality fasteners to industries like oil & gas, petrochemicals, marine, and construction in domestic as well as international markets.
Duplex Steel S32205 Nuts consist of Chromium (22%), Nickel (5–6.5%), Molybdenum (3%), Nitrogen (0.14–0.20%), Manganese (≤2%), and Iron in the remainder. The above composition provides excellent resistance against pitting, crevice corrosion, and stress corrosion cracking. Mechanically, they have a tensile strength of approximately 620 MPa, a yield strength of 450 MPa, and an elongation of 25%. Physically, they have a density of 7.8 g/cm³ and a melting point around 1400°C. The properties offer an ideal combination of strength and resistance to corrosion and thus enable the nuts to be used efficiently in aggressive chemical, marine, and high-stress environments.

Duplex Steel S32205 Nuts are universally applied in industries that require high strength and superior corrosion resistance. Typical industries involve offshore platforms for oil and gas, shipbuilding and marine, chemical plants, and desalination plants. Duplex Steel S32205 Nuts are utilized to secure equipment, pipelines, structural parts, and machinery that work under high pressure and in corrosive environments. Their resistance to chloride stress corrosion cracking makes them appropriate for application in seawater and aggressive chemical exposures. They also have applications in power generation, pulp and paper, and infrastructure developments where reliability, long life, and safe fastening are critical under harsh conditions of service.
