George Metals is a reliable Houston-based USA manufacturer and supplier of top-grade Monel Hex Bars, providing durable, corrosion-resistant materials with demanding industrial processes. Renowned for their quality engineering and following international standards such as ASTM B164 and ASTM B865, George Metals supplies Monel Hex Bars in several grades such as Monel 400 and Monel K500. These bars are developed to satisfy the demands of industries including marine, oil and gas, chemical processing, and aerospace. With custom size, quick delivery, and technical support, George Metals guarantees consistent performance and customer satisfaction for mission-critical alloy parts.
Monel Hex Bars consist mostly of nickel (at most 67%) and copper (approximately 28–34%), with small additions of iron, manganese, silicon, and in the case of Monel K500, aluminum and titanium for age-hardening. Monel 400 possesses high corrosion resistance with reasonable strength (tensile strength ~550 MPa), whereas Monel K500 offers greater mechanical strength (tensile strength up to 965 MPa) and hardness via precipitation hardening. Both grades of the material exhibit toughness in sub-zero temperatures, are resistant to acids and seawater corrosion, and have structural integrity under mechanical and thermal stress, thus being extremely versatile for numerous engineering applications.
