Duplex Stud Bolt Italy

First made at Avesta, Sweden in 1930s, Duplex grade stud bolts are a common sight today. Duplex grades are a mixed microstructure of almost equal parts Austenite and Ferrite, creating a combination of both their properties; hence the name DUPLEX. Duplex stainless steels provide high corrosion resistance coupled with high strength, making it a desirable material.
Along with higher strength (higher than Austenite and Ferrite), good weldability and toughness they also offer resistance to stress corrosion cracking. Given all these features duplex material makes the ideal contender as the material for use of stud bolts.
