George Metals, located in Houston, USA, is a reliable manufacturer and supplier of high-performance Jethete M152 Steel Bars, specifically designed for tough high-temperature and high-stress environments. Jethete M152 is a martensitic stainless steel alloy primarily created for aerospace and turbine applications, boasting remarkable creep resistance, fatigue strength, and oxidation resistance. Produced in accordance with AMS 5719 and other aerospace standards, George Metals offers Jethete M152 bars in a variety of diameters and lengths, all heat-treated for peak performance. These bars find extensive use in gas turbines, jet engines, nuclear power systems, and aerospace components that demand long-term stability under thermal and mechanical stress.
Jethete M152 Steel Bars from George Metals are made up of approximately 0.12% carbon, 2.5% chromium, 1.5% molybdenum, and 0.9% vanadium, with iron as the base. This carefully controlled composition boosts high-temperature tensile strength, creep resistance, and hardenability. After undergoing heat treatment, the bars can reach tensile strengths between 1,100 and 1,300 MPa, yield strength exceeding 900 MPa, and impressive fatigue resistance. Typically, Jethete M152 is delivered in a quenched and tempered state. George Metals guarantees that each bar is rigorously tested for mechanical integrity, grain structure, and dimensional accuracy, making them perfect for mission-critical applications in extreme conditions.
