Home > Jethete M152 Round Bars
Okoye Nickel Alloys, a reputable manufacturer and supplier based in Kinshasa, Congo, specializes in high-performance Jethete M152 Round Bars, perfect for the rigorous demands of engineering and aerospace applications. Jethete M152 is a martensitic stainless steel alloy celebrated for its outstanding strength, toughness, and resistance to oxidation, even at high temperatures. These round bars are designed to be heat-treatable and boast excellent creep and fatigue resistance, making them ideal for use in turbine blades, fasteners, and other high-stress components. Okoye Nickel Alloys is committed to delivering products with superior precision, consistent mechanical properties, and strict adherence to international standards, ensuring that their Jethete M152 Round Bars are well-suited for critical high-temperature and structural applications.
Jethete M152 Round Bars are made up of Cr (12%), Ni (2.5%), Mo (1.25%), V (0.2%), and a balanced amount of Fe, with controlled additions of C, Si, and Mn. This alloy forms a robust martensitic structure after heat treatment, providing impressive tensile strength (~1,000 MPa) and yield strength (~850 MPa), along with good ductility and impact toughness. Jethete M152 also offers excellent oxidation resistance up to 650°C, along with superior fatigue and creep resistance. Its reliable mechanical performance under extreme conditions makes it a top choice for aerospace, turbine, and power generation applications.
