Houston-based George Metals is a prominent producer and distributor of high-strength Monel K500 Bars and Rods used in industries requiring superior strength and corrosion resistance. With expertise in nickel-based alloys, George Metals produces precision-fabricated Monel K500 products for severe applications like marine, oil and gas, and chemical processing. With emphasis on quality, adherence to ASTM B865 standards, and sizes and finishes to order, George Metals provides assured and timely supply. With in-house expertise and state-of-the-art processing facilities, they are a partner of choice for mission-critical applications demanding heavy-duty and high-strength alloy materials.
Monel K500 Rods and Bars contain about 63% nickel and 30% copper along with minor but significant amounts of aluminum (2.3–3.15%) and titanium (0.35–0.85%) as age-hardening additions. The alloy reconciles Monel 400’s superior resistance to corrosion with increased mechanical hardness and strength. It has a tensile strength of up to 965 MPa, yield strength of approximately 690 MPa, and elongation of around 20%. Monel K500 maintains toughness below sub-zero temperatures and is not magnetic even on aging. The alloy also shows excellent resistance to stress-corrosion cracking, erosion, and pitting in marine and chemical environments.
