Duplex Steel F51 / 31803/ 1.4462 Fasteners are becoming increasingly popular in several industries worldwide, such as the chemical and petrochemical, oil and gas, and marine industries. It is because of its excellent strength, resistance, and durability, making it an ideal material for fasteners. Duplex Steel F51/31803/1.4462 Fasteners have a unique combination of corrosion resistance, strength, and durability, making them ideal for use in demanding environments.

Duplex Steel F51 Fasteners Features

​

Duplex Steel F51 fasteners, also known as SAF 2205 fasteners, are duplex stainless steel fasteners that are highly resistant to corrosion and have high strength. They are composed of ferritic and austenitic stainless steel with higher chromium, molybdenum, and nickel content than standard stainless steel. Due to its structure, Duplex Steel F51 fasteners resist corrosion, cracking, and pitting from various chemicals, making them ideal for use in a harsh environment. Their features make them popular in the chemical and petrochemical industry, where they are used in pumps, valves, heat exchangers, and other equipment that require extreme resistance to corrosive environments.

Duplex Steel 31803 Fasteners Corrosion Resistance

Duplex Steel 31803 Fasteners are duplex stainless steel fasteners that have improved corrosion resistance over standard austenitic stainless steel. The 31803 fasteners have higher molybdenum, nitrogen, and chromium content, which makes them more resistant to various types of corrosion, such as crevice corrosion, stress corrosion cracking, and pitting. The combination of high strength and excellent corrosion resistance makes them preferred in the offshore and marine industries for fastening saltwater pipelines, risers, and offshore platform structures, among other applications.
