Duplex Steel Fasteners Manufacturer

Duplex steels are becoming more popular in the fastener business for a variety of reasons, including increased strength – which helps with weight savings – and improved corrosion resistance, particularly in terms of stress corrosion cracking. The duplex was developed to achieve a balance between the austenitic and ferritic types of conventional steels, which provides a number of benefits in fastening, including increased structural strength, enhanced weldability, good toughness, and improved stress corrosion cracking resistance.

Duplex stainless steel's resistance to stress corrosion cracking, in particular, is a true hallmark, while other stainless steel struggles in this area. These Duplex steel fasteners are used widely in industrial fields, mechanical works, and many more. Duplex Steel Fasteners are constructed from an alloy that has a high content of chromium and low to moderate content of nickel. The high chromium content present in these Duplex Steel Fasteners gives them high tensile strength along with increased hardness and toughness. These fasteners have high strength and are superior to regular grade stainless steel in terms of strength and corrosion resistance. These Duplex steel fasteners are quite advantageous and are applicable in a variety of industries
