Monel K500 Stud in 12 mm UNC thread × 75 mm length is a high-strength, precipitation-hardenable nickel–copper alloy fastener designed for demanding mechanical and corrosive service conditions. Monel K500 combines the excellent corrosion resistance of Monel 400 with significantly higher strength and hardness achieved through age hardening, making it ideal for critical bolting applications.

This 12 mm UNC threaded stud offers excellent resistance to seawater, marine atmospheres, hydrofluoric acid, alkalis, and non-oxidizing acids, along with superior resistance to stress corrosion cracking and galling. The 75 mm length ensures adequate thread engagement and load-bearing capacity in high-pressure and high-vibration assemblies. Monel K500 studs also retain their mechanical properties at sub-zero temperatures, making them suitable for cryogenic service.

Monel K500 exhibits high tensile and yield strength, good fatigue resistance, and reliable performance under cyclic loading. These properties make it a preferred material for studs used in valves, pumps, flanges, and structural assemblies exposed to aggressive environments.

Equivalent and specification designations for Monel K500 include UNS N05500, ASTM B865 / ASTM F467 (for fasteners), AMS 4675 / AMS 4676, and EN 2.4375, ensuring global standard compliance.

These Monel K500 Studs, 12 mm UNC × 75 mm length, are manufactured by Raj Metals, Mumbai. For technical specifications, availability, and commercial inquiries, please contact +91 81045 97964.

Monel K500 Round Bar in 25 mm diameter is a high-strength, precipitation-hardenable nickel–copper alloy product developed for applications requiring excellent corrosion resistance combined with superior mechanical strength. Monel K500 retains the outstanding corrosion resistance of Monel 400 while offering significantly higher tensile and yield strength through age-hardening, making it suitable for severe service conditions.

The 25 mm diameter round bar provides uniform metallurgical properties, good surface quality, and reliable machinability for precision components. Monel K500 exhibits excellent resistance to seawater, marine atmospheres, hydrofluoric acid, alkalis, and non-oxidizing acids, along with strong resistance to stress corrosion cracking and galling. It also maintains its mechanical properties at sub-zero temperatures, making it suitable for cryogenic applications.

Monel K500 round bars are widely used in shafts, fasteners, valves, pump components, marine hardware, oil and gas equipment, and offshore structures where high strength, corrosion resistance, and long service life are essential.

Equivalent and standard designations for Monel K500 include UNS N05500, ASTM B865, ASTM B164, AMS 4675 / AMS 4676, and EN 2.4375, ensuring compliance with major international standards.

These Monel K500 Round Bars, 25 mm diameter, are supplied by Raj Metals, Mumbai. For technical specifications, availability, and commercial inquiries, please contact +91 81045 97964.

Monel 400 Round Bar – Ø40 mm is a high-performance nickel–copper alloy bar widely used where excellent corrosion resistance and good mechanical strength are required. It performs exceptionally well in seawater, brine, acidic and alkaline environments, and maintains stable properties over a wide temperature range.

Monel 400 is commercially known as Nickel Copper Alloy 400 / NiCu30Fe and is designated under UNS N04400. It conforms to international standards such as ASTM B166 (round bars) and ASTM B164 (forgings), with European equivalent EN 2.4360. These standards ensure consistent chemistry, strength, and performance for critical industrial applications.

From a technical perspective, Monel 400 contains a high percentage of nickel with copper as the principal alloying element, giving it excellent resistance to stress corrosion cracking and pitting. It offers good tensile strength, high ductility, and reliable performance at both sub-zero and elevated temperatures, making it suitable for demanding service conditions.

Monel 400 Round Bars (40 mm dia) are commonly used in marine shafts, pump and valve components, heat exchangers, chemical processing equipment, oil & gas hardware, and offshore structures. Raj Metals, Mumbai supplies Monel 400 bars with assured quality, traceability, and prompt delivery for both domestic and export requirements.
