The Duplex Steel 329 Fasteners are constructed of a mix of Chromium and Nickel. The Duplex Steel 329 Fasteners are non-magnetic and can tolerate oxidation temperatures of up to 1800 ° F. The Duplex Steel 329 Fasteners are extremely resistant to oxidation and corrosion in a wide range of conditions. The Duplex Steel 329 Fasteners have a high degree of formability. They are also quite machinable. They can work well at temperatures ranging from cryogenic to 2000 ° F. Duplex 329 fasteners also contain trace amounts of niobium and molybdenum, which increase their strength and hardness.
The duplex Steel 329 Fasteners also provide excellent resistance to creep ruptures. Duplex Steel 329 Fasteners have excellent welding qualities and may be welded using traditional methods, both automatic and manual. They are corrosion-resistant to contaminated chloride conditions due to their high chromium and molybdenum content.
Implementations of Duplex Steel 329 Fasteners can be found in a variety of industrial industries. They are extensively utilized in the manufacture of aircraft ducting systems and exhaust systems. They are also utilized to make chemical processing equipment and specialized marine equipment.
Duplex Steel 329 Fasteners Advantages
Many Duplex Steel 329 Fasteners are up to twice as strong as austenitic and ferritic stainless steel grades.
Ductility and high toughness
Duplex Steel 329 Fasteners is more malleable under pressure than ferritic grades and has higher toughness. Though they frequently provide lower values than austenitic steels, the unique structure and properties of duplex steel frequently offset any issues.
Corrosion Resistance is High
Duplex Steel 329 Fasteners have equivalent (or superior) corrosion resistance to ordinary austenitic grades, depending on the grade. Steels display strong resistance to crevice corrosion and chloride pitting in alloys with enhanced nitrogen, molybdenum, and chromium.
Duplex Steel 329 Fasteners provides all of the benefits listed above while requiring lower quantities of molybdenum and nickel. This implies it is a less expensive option than many typical austenitic stainless steel grades. Duplex alloy prices are frequently less variable than other steel grades, making it easier to anticipate expenses – both upfront and over time. Because of the increased strength and corrosion resistance, many duplex stainless parts can be thinner than their austenitic counterparts, resulting in cheaper prices.
