Product Details:

Aashish Metal & Alloys is a leading manufacturer and exporter of Monel K500 Flanges, engineered for superior performance in demanding industrial applications. Monel K500 is a precipitation-hardened nickel-copper alloy with added aluminum and titanium, offering exceptional strength, hardness, and corrosion resistance, even in marine and chemical environments. These flanges combine the excellent corrosion resistance of Monel 400 with greater mechanical strength and wear resistance, making them ideal for high-stress and corrosive conditions.

Our Monel K500 flanges are manufactured in various types including Slip On, Weld Neck, Blind, Socket Weld, Lap Joint, Threaded, and Long Weld Neck, conforming to international standards such as ASME, ASTM, and ANSI. They are widely used in marine engineering, oil & gas, chemical processing, offshore drilling, heat exchangers, pump & valve components, and desalination plants. The material retains its toughness and non-magnetic properties, even at sub-zero temperatures, ensuring long service life.

Key properties include:

• Excellent corrosion resistance in seawater, acidic, and alkaline environments

• High tensile and yield strength

• Non-magnetic in annealed and hardened condition

• Good oxidation resistance up to 600°C

• Superior resistance to stress corrosion cracking

Aashish Metal & Alloys ensures precision machining, dimensional accuracy, and superior surface finish. Our Monel K500 flanges undergo rigorous quality checks, including material testing, PMI, ultrasonic testing, and hydrostatic testing to ensure compliance with client specifications. Available in sizes from ½” to 48” and pressure ratings from 150# to 2500#, we also provide customized dimensions and special coatings on request.

With a strong focus on quality, timely delivery, and competitive pricing, we supply Monel K500 flanges to clients across the globe, ensuring reliable performance in the most challenging environments.
