With a solid reputation for technical know-how, speedy service, and material integrity, Themba Nickel Alloys has earned the trust of both local and global markets.
These Duplex Steel Washers are made from a stainless steel alloy featuring a dual-phase microstructure—roughly equal parts austenite and ferrite. This unique structure grants them exceptional mechanical strength and a corrosion resistance that far surpasses standard austenitic grades. With tensile strength typically falling between 620 and 900 MPa, these washers can handle high-stress situations and are particularly resilient against stress corrosion cracking, pitting, and crevice corrosion. They also boast impressive dimensional stability and fatigue resistance, even in chloride-rich or marine settings, making them perfect for demanding structural and fastening tasks.
