Monel Forged Fittings
Stellanox Steel supplies top-quality Monel Forged Fittings engineered for use in high-pressure, corrosive, and high-temperature environments. Made from premium Monel 400 and Monel K500, these forged fittings provide superior mechanical strength, exceptional seawater and acid resistance, and long-term performance in industries such as marine, offshore, chemical processing, oil & gas, and power generation.
Our forged fittings are available in socket weld and threaded (NPT/BSP) configurations, fully compliant with international standards such as ASME B16.11, ASTM B564, and MSS SP-83.
What are Monel Forged Fittings?
Monel Forged Fittings are compact, high-strength components designed to handle small-diameter, high-pressure piping connections. Forged from solid alloy billets, these fittings offer dense grain structures, enhanced toughness, and exceptional corrosion resistance, particularly in chloride-rich, brine, and acidic environments.
They are used in critical systems where leak prevention, pressure containment, and space constraints are major considerations.
