George Metals, a leading manufacturer and supplier based in Houston, USA, is dedicated to providing top-notch Monel Square Bars designed for tough industrial settings. Monel, a nickel-copper alloy celebrated for its remarkable resistance to seawater, acids, and other corrosive substances, is perfect for high-performance engineering tasks. George Metals offers Monel square bars in various grades, including Monel 400 and Monel K500, crafted to comply with ASTM B164 and B865 standards. With precise machining, strict dimensional tolerances, and outstanding mechanical properties, George Metals guarantees that its Monel square bars deliver unmatched durability for industries like marine, chemical processing, aerospace, and oil & gas.
Monel Square Bars are mainly made up of about 63% Nickel and 30–34% Copper, along with trace amounts of iron, manganese, carbon, and silicon. This alloy provides excellent corrosion resistance in both acidic and marine environments, coupled with high mechanical strength. Monel 400 boasts a tensile strength of around 550–700 MPa, while Monel K500, which includes aluminum and titanium, can surpass 1000 MPa. Both grades maintain their toughness across a wide temperature range. George Metals ensures that its Monel square bars are of consistent quality, precision, and metallurgical integrity, making them ideal for machining, welding, and high-stress applications.
