George Metals, USA, Houston-based, is a trusted supplier and producer of Monel K500 Forgings, offering high-strength, corrosion-resistant parts for the most demanding applications. Renowned for their state-of-the-art forging technology and compliance with international quality standards (ASTM B564, ASME SB564), George Metals offers Monel K500 products with superior mechanical performance and durability. These forgings are perfect for uses demanding resistance to severe marine, chemical, and high-pressure exposures. With on-site machining, technical capabilities, and quick turnaround, George Metals is an approved supplier of precision-forged Monel K500 parts to many industries.
Monel K500 Forgings consist of a precipitation-hardenable nickel-copper alloy having around 63% nickel, 30% copper, with aluminum (2.3–3.15%) and titanium (0.35–0.85%) additions. This alloy takes the superior corrosion resistance of Monel 400 and adds more strength and hardness via age hardening. Physical properties are tensile strength of up to 965 MPa, yield strength of about 690 MPa, and elongation of 20%+. Monel K500 maintains toughness and strength at sub-zero temperatures and has excellent stress-corrosion cracking and erosion resistance, good for severe service conditions.
