Introduction: Crafted from Mumbai, Built for the Harshest Environments

At ViramiSteel Hub, we’re rooted in the dynamic industrial core of Mumbai, and we understand what factories, refineries, and offshore plants demand: pipe fittings that don’t just last but excel. That’s why we’re proud to offer Monel 400 and Monel 500 (K-500) pipe fittings engineered to endure where ordinary metals give way.

Why Monel 400 & 500 Matter Especially from ViramiSteel

Monel 400 (UNS N04400)

A nickel-copper alloy celebrated for its unyielding corrosion resistance across acidic, alkaline, and marine environments. It maintains mechanical strength even at sub-zero temperatures, making it invaluable for cryogenic and marine applications.

Element Content (%)
Nickel, Ni Remainder
Copper, Cu 28-34
Iron, Fe 2.5 max
Manganese, Mn 2 max
Silicon, Si 0.5 max
Carbon, C 0.3 max
Sulphur, S 0.024

Monel 500 (K-500, UNS N05500)

Bolstered with aluminum and titanium, this age-hardened version combines Monel’s legendary corrosion resistance with dramatically improved strength and hardness meeting demands in high-pressure or mechanical stress environments.

Nickel (plus Cobalt) 63% min
Carbon 0.25% max
Manganese 1.5% max
Iron 2% max
Sulfur 0.01% max
Silicon 0.5% max
Copper 7–33%
Aluminum 2.30–3.15%
Titanium 0.35–0.85%

How These Alloys Compare (Quick Snapshot)

Alloy Tensile Strength Yield Strength Corrosion Resistance
Monel 400 ~480–690 MPa (~70–100 ksi) ~170–345 MPa (~25–50 ksi) Excellent in various media
K-500 ~760–965 MPa (~110–140 ksi) ~450–690 MPa (~65–100 ksi) Equally strong, slight SCC risk

Industry Standards You Can Trust

We manufacture to globally recognized specs, ensuring seamless integration and uncompromised reliability:

  • Butt-Weld Fittings (Monel 400 / K-500) ASTM B366 / ASME SB366, compliant with ANSI B16.9, B16.28, and MSS-SP-43 dimensions. Sizes range from ½″–48″ (seamless up to ~10″).
  • Forged (Threaded & Socket-Weld) Fittings ASTM B564 / ASME SB564, covering 1/8″–4″, with pressure classes from 2000 to 9000 lbs.

Applications Where ViramiSteel’s Monel Fittings Shine

These fittings are engineered so as to meet real-world challenges:

  • Corrosive Environments include environments such as strong acids and also seawater. Chemical reactors can also be included here.
  • Cryogenic settings retain for toughness. This occurs even when temperatures are quite low. K-500’s tensile strength and yield strength support demanding pressure regimes.
  • Mechanical resilience combines along with corrosion resistance in Marine & Mechanical Stress Zones.

Why Choose ViramiSteel Hub?

These fittings are engineered so as to meet real-world challenges:

  • Mumbai-based manufacturing, global standards – From local yards to global platforms, we blend agility with quality.
  • Certifications that speak volumes – All fittings include material test reports (EN 10204), fully compliant with ASTM/ASME norms.
  • Customization at core – Non-standard thread types, custom wall thicknesses, and fabrication-ready dimensions – tell us your specs, and we’ll meet them.
  • Built for longevity – Our fittings are more than components they’re peace-of-mind investments.

Conclusion: Reliability You Can Count On

In a world in which downtime or corrosion may cost millions, pipe fittings made of Monel 400 and Monel 500 from ViramiSteel Hub perform steadfastly and also show resilience. Our fittings are built for lasting use in cryogenic facilities. They are also surely built for lasting success whether you’re in various refineries or multiple marine setups.
