Duplex Steel F51 / UNS S31803 / 329LL / URANUS 45N filler wires are designed to excel in making welds of duplex stainless steels such as F51, 329LL and URANUS 45N. Designers craft these filler wires with great strength, excellent resistance to corrosion and longevity to meet the toughest challenges. Such materials are well suited for use in areas requiring efficiency, including oil and gas, marine, chemical processing, power generation and desalination plants.
Because Duplex Steel F51 / UNS S31803 / 329LL / URANUS 45N filler wires have balanced amounts of chromium, molybdenum and nickel, their resistance to pitting, crevice corrosion and stress corrosion cracking is high. Combining ferritic and austenitic phases in duplex metal gives it higher strength and greater toughness in chloride-containing environments.
The weldability of these filler wires and their small rate of thermal expansion help reduce both distortion and stress in the welds. They can be applied to MIG, TIG and SAW welding methods and are designed for manual as well as automated welding.
These wires abide by worldwide standards and are sold in many diameters, sizes of spools and different packaging, serving a variety of welding needs. They are straightforward to use and ensure reliable performance, along with sturdy arcs and good looking welds.
All in all, Duplex Steel F51 / UNS S31803 / 329LL / URANUS 45N wires are best for making strong and corrosion-resistant welds. Since these tools are reliable in tough applications, they serve for a long time, need fewer repairs and are economical, so many fabricators and engineers around the world are interested in them.
