Duplex Steel 329 Fasteners are essential in various industries like automotive, construction, and aerospace. The fastener industry offers numerous materials, sizes, and types of fasteners to meet specific application requirements. One such material is Duplex Steel 329. This type of steel has exceptional properties that make it an ideal material for high-stress applications, including fasteners.
Duplex Steel F329 Fasteners Features
Duplex Steel 329 is a high-strength, corrosion-resistant material with excellent toughness, making it an ideal material for fasteners. Duplex Steel 329 are specially designed fasteners that can bear heavy loads and high-pressure applications. They are known for their high corrosion resistance to chloride-rich environments and high-stress corrosion cracking. Duplex Steel 329 fasteners also have exceptional durability and can withstand high temperatures.

Duplex Steel 329 Fasteners Corrosion Resistance
Duplex Steel 329 Fasteners have high resistance to general, pitting, and crevice corrosion. They also have superior toughness and flexibility, which makes them suitable for use in highly corrosive environments, like seawater, chemical processing plants and offshore oil and gas drilling platforms. Duplex Steel 329 fasteners also have excellent stress corrosion cracking resistance, which is crucial in the fastener industry, where preventing cracks is critical.
Duplex Steel 329 Fasteners Chemical Composition
Duplex Steel 329 combines austenitic and ferritic stainless steel, containing 25% chromium and 5% nickel. It also has high levels of molybdenum, nitrogen, and copper, which impart excellent corrosion resistance properties to the material. The high levels of molybdenum and nitrogen in the chemical composition of Duplex Steel 329 Fasteners increase its strength, making it a popular choice for fasteners used in high-pressure applications.
Duplex Steel 329 Fasteners Machining
Duplex Steel 329 Fasteners are machinable but with care. The properties of Duplex Steel 329 Fasteners make them slightly more difficult to machine than austenitic stainless steel. However, modern machine tools, cutting tools, and techniques can be used to machine duplex stainless steel to produce precise parts and fasteners as needed. Machining duplex steel requires a slow and stable cutting speed, cutting fluid, and proper tooling to avoid chatter and vibration.
