Wai Nickel Alloys is a reputable manufacturer and supplier located in Naypyidaw, Myanmar, and they specialize in high-performance Monel 400 Stud Bolts. These bolts are celebrated for their exceptional corrosion resistance, strength, and durability. Crafted from a solid-solution nickel-copper alloy, they excel in resisting seawater, acids, and alkalis, even in the toughest marine and chemical settings. Wai Nickel Alloys takes pride in ensuring precise threading, top-notch finishing, and compliance with global standards, making their Monel 400 Stud Bolts perfect for demanding industrial applications where reliability and longevity are essential.
Monel 400 Stud Bolts consist of about 63% nickel and 28–34% copper, along with trace amounts of iron, manganese, and silicon. This unique blend grants them impressive resistance to corrosion from seawater, hydrofluoric acid, and alkalis. They boast high tensile strength (around 480 MPa), excellent toughness, and good ductility across a broad temperature range. The alloy remains mechanically stable under stress and is mostly non-magnetic. Additionally, Monel 400 Stud Bolts show remarkable resistance to pitting, stress-corrosion cracking, and general wear in both marine and chemical environments.
