Operating from the heart of Kinshasa, Okoye Nickel Alloys is a trusted partner for industry, renowned for supplying robust materials that stand up to the most demanding environments. We take particular pride in our Duplex Steel Washers, components engineered to offer an exceptional balance of strength and resilience. We understand that the success of your projects depends on the quality of even the smallest parts, and we are committed to providing washers that deliver unwavering performance and long-term reliability, supporting the growth and durability of infrastructure across the region and beyond.
The composition of these washers is a sophisticated blend, primarily chromium, nickel, and molybdenum, with a dual-phase microstructure that gives Duplex steel its name. This unique structure is the source of their remarkable mechanical properties. They offer a yield strength that is approximately double that of standard austenitic stainless steels, alongside excellent toughness and impressive flexibility. This combination allows our washers to handle significantly higher loads and resist stress-related failures far better than ordinary alternatives.
