What sets Themba Nickel Alloys’ Super Duplex Ball Valves apart is their unique microstructure, which consists of about 50% austenite and 50% ferrite, along with a rich mix of chromium (24–26%), nickel (6–8%), and molybdenum (3–5%). This special composition gives them exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. Plus, they boast impressive mechanical strength, with tensile strength between 850–950 MPa and yield strength of 550–650 MPa, all while ensuring excellent toughness, impact resistance, and durability. These superior material properties guarantee reliable performance, even in high-temperature and chloride-rich environments.
