Houston, USA-based George Metals is a trusted supplier and manufacturer of Hastelloy X Rods and Bars, providing high-temperature and corrosion-resistant alloy bars and rods designed for rigorous use in aerospace, chemical processing, and industrial heat exchanger systems. Manufactured to ASTM B572 and AMS 5754 specifications, these bars and rods have excellent oxidation resistance, thermal stability, and high-temperature strength. George Metals offers special sizes, rapid shipment, and technical assistance, making them a reliable supplier to customers needing the best available materials in hostile, high-temperature, high-stress conditions.
Hastelloy X Bars and Rods consist mainly of about 47% nickel, 22% chromium, 18.5% iron, and 9% molybdenum, along with cobalt and trace additions to improve high-temperature performance. This alloy composition provides Hastelloy X its remarkable mechanical properties in terms of tensile strength of about 760 MPa, yield strength of about 340 MPa, and elongation of about 30–45%. It has strength and oxidation resistance up to 1200 °C (2200 °F), provides good fabricability and weldability, and resists carburization and stress corrosion cracking—making it perfect for harsh thermal and corrosive conditions.
