Duplex Stainless Steel Screws, Fasteners and Fixings
Duplex Stainless Steels are becoming increasingly common within the fastener industry for a number of reasons, including higher strength which aids in weight saving – as well as greater corrosion resistance, particularly regarding stress corrosion cracking.
Duplex is also considered more cost-effective.
Advantages in steel making techniques, and specifically control of nitrogen content have made duplex steels more popular in recent years.
Duplex is created to try and reach an equal balance between the austenitic and ferritic types of standard steels, which provides a number of advantages in fixings, such as higher strength in structural applications, improved weldability, good toughness, and better resistance to stress corrosion cracking.
Particularly, the resistance to stress corrosion cracking is a true highlight of duplex stainless steel as other stainless steels struggle in this area – however, there is a negative, as they are more difficult to form and machine than austenitic steels.
