In offshore rigs, marine pipelines, and chemical reactors, the wrong material choice can mean:
Rapid pitting & crevice corrosion in seawater
Acid leaks from weak alloys
Project delays due to failed inspections
That’s why EPCs and engineers trust Monel 400 (UNS N04400) — the alloy that performs in seawater, hydrofluoric acid, alkalis, and brine environments.
At Navgraha Steels INC, Mumbai, we supply Monel 400 plates, sheets & coils from the most trusted global mills:
