Hakan Nickel Alloys, located in Istanbul, Turkey, is a trusted name when it comes to high-performance fastening solutions, particularly Duplex Steel S32205 Fasteners. These fasteners are crafted to deliver exceptional mechanical strength and corrosion resistance, making them perfect for tough and high-stress environments. They’re manufactured to meet international standards and come in a wide range of sizes, threads, and configurations, making them a go-to choice for industries like oil and gas, marine, petrochemicals, and offshore engineering.
What sets Duplex Steel S32205 Fasteners apart is their unique composition, which includes nitrogen-enhanced duplex stainless steel alloy with about 22% chromium, 5–6% nickel, and 3% molybdenum, all balanced in a ferritic-austenitic structure. This blend provides remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. These fasteners boast nearly double the tensile and yield strength of standard austenitic stainless steels while still offering excellent toughness, fatigue resistance, and thermal stability, even in demanding conditions.
