At Thomas Smith Fasteners, we offer Super Duplex stainless steel bolts and fasteners with short production lead times
At Thomas Smith Fasteners, we manufacture high-quality fasteners using Super Duplex stainless steel grades UNS 32750 and UNS 32760.
These advanced materials offer superior corrosion resistance compared to standard Duplex grades, along with higher tensile and yield strength. They also provide excellent toughness and ductility, as well as strong resistance to stress corrosion cracking — making them a reliable, cost-effective choice for demanding applications.
UNS 32760 contains slightly higher levels of copper and tungsten than UNS 32750, giving it enhanced resistance to aggressive inorganic acids such as sulphuric and hydrochloric acid.
If you're looking for exceptional performance in harsh environments without compromising on cost-efficiency, our Super Duplex fasteners deliver long-lasting results you can depend on.
