When your operations face harsh marine environments, hydrofluoric acid, or highly corrosive chemical processing, standard fasteners are a liability. At Horizon Metal and Alloys, we engineer and manufacture Monel Alloy 400 (UNS N04400) nuts, bolts, and fasteners specifically designed to maintain mechanical strength and resist localized corrosion in these exact conditions.
As an ISO-certified manufacturer, we don’t just supply fasteners; we guarantee their integrity. Every Monel 400 component we produce complies strictly with ASTM F467 / F468 and ASME standards, backed by 100% material traceability and EN 10204 3.1 Mill Test Certificates (MTC). Whether you are securing offshore oil platforms or outfitting a desalination plant, our fasteners provide the documented reliability your critical infrastructure demands.
With years of manufacturing expertise, competitive pricing, ready stock, and worldwide export capabilities, we have become a trusted Monel Alloy 400 nut bolt supplier for customers across India, the Middle East, Europe, North America, Southeast Asia, and Africa.
Monel Alloy 400 is a solid-solution nickel-copper alloy (approximately 63% nickel and 28–34% copper). It is renowned for its outstanding corrosion resistance in reducing and neutral environments, as well as its ability to maintain excellent mechanical strength over a wide temperature range, including cryogenic temperatures. Because of its superior resistance to rapidly flowing brackish water and seawater, it is widely considered the industry standard for marine and chemical engineering fasteners.
We manufacture and supply a comprehensive range of Monel Alloy 400 fasteners, including:
