Monel alloys, specifically 400 and K500, are the gold standard for fastening in hydrofluoric acid alkylation units and subsea oil installations. SRG Fasteners manufactures precision Monel hardware that remains virtually immune to stress-corrosion cracking and pitting in chloride-rich environments.
Our Monel K500 bolts offer the same corrosion resistance as Monel 400 but with greater strength and hardness, making them ideal for high-load offshore equipment. We provide full material certification to ensure compliance with the strict safety standards of the global energy sector.
Whether you are maintaining refinery heat exchangers or deploying subsea Christmas trees, our Monel fastening solutions ensure long-term reliability and zero-maintenance operations in extreme conditions.
What is the difference between Monel 400 and K500?
Monel 400 is highly corrosion-resistant but has lower strength, while K500 is age-hardened to provide significantly higher tensile and yield strength while maintaining similar corrosion resistance.
Do you supply Monel fasteners for hydrofluoric acid units?
Yes, our Monel 400 fasteners are specifically recommended for use in HF alkylation units due to their exceptional resistance to acid attack.
