We manufacture a comprehensive range of Alloy 400 fasteners engineered to survive severe marine environments and halogenic acids.

Monel 400 Fasteners can only be hardened through cold working, not through heat treatment. They exhibit excellent mechanical properties at sub-zero temperatures, retaining toughness without undergoing a ductile-to-brittle transition. Below are the standard mechanical properties:

With a minimum of 63% nickel and 28-34% copper, Monel 400 components are virtually immune to chloride-ion stress-corrosion cracking and highly resistant to rapid localized attack in seawater.

• Marine Engineering: Fasteners for seawater valves, pump shafts, propeller hardware, and offshore splash zones.
• Chemical Processing: Crucial for equipment handling hydrofluoric acid (HF) alkylation, sulfuric acid, and caustic alkalis.
• Desalination: Piping systems, heat exchangers, and evaporators utilizing high-temperature brine.
• Oil & Gas: Fasteners used in distillation tower internals and crude petroleum stills.

As a primary manufacturer based in Mumbai, our quality control goes beyond standard chemical analysis. We conduct rigorous first-hand testing on all Monel 400 Fasteners to ensure they meet the stringent safety requirements of marine engineers and chemical plant operators.

• Ultrasonic Testing (UT): Internal flaw detection performed on raw billets prior to machining.
• Destructive Testing: In-house tensile, yield, and elongation testing to verify structural integrity under load.
• PMI (Positive Material Identification): 100% optical emission spectroscopy scanning prior to dispatch to guarantee the precise nickel-copper ratio.
