During a critical shutdown at a petrochemical complex in Gujarat, where furnace radiant tubes succumbed to rapid oxidation at 1100°C, causing $2M in losses, the team pivoted to Haynes® 214 Plates (UNS N07214). Forming a tenacious alumina (Al₂O₃) scale, these plates extended service life by over 5x versus RA 333 or Incoloy 800H, minimizing downtime in harsh, oxidizing environments. Trusted stockists like Aurico Alloys LLP supplied Haynes International mill specification for UNS N07214-compliant plates, restoring operations with peak reliability.

Haynes® 214 plates dominate in chemical, oil & gas, marine, pharma, and power sectors requiring unparalleled oxidation resistance above 955°C (1750°F). This Ni-Cr-Al wrought alloy outperforms conventional heat-resisters by prioritizing Al₂O₃ scale formation over Cr₂O₃, thriving in air, combustion gases, or chlorine-contaminated flows up to 1315°C perfect for industrial furnace radiant tubes, muffles, and gas turbine honeycombs.
Why opt for Haynes 214 over alternatives like Inconel 600 or RA85H? Its selective alumina layer delivers <0.5 mg/cm² metal loss in 1000h at 1150°C (vs 5-10x higher for others), plus resistance to carburization, nitriding, and chlorides, cutting maintenance 50-70% for fabricators and OEMs. Chlorination-resistant plates excel in petrochemical piping and hydrocarbon plants.

Applications & Benefits
Why this grade
Haynes® 214 carries about 4.5% aluminium, so it forms an alumina scale rather than a chromia one. That gives oxidation resistance to roughly 1200°C, the highest in the Haynes high-temperature range, but it is a thin-section alloy — honeycomb seals, foil and catalytic converter substrates — rather than a load-bearing structural one.
- Industrial Heating: Haynes 214 plate suppliers in Mumbai for industrial furnace radiant tubes/muffles, mesh belts, heat-treating fixtures, ceramic kiln furniture.
- Power/Gas Turbines: High-temperature oxidation resistant Alloy 214 plates for land-based gas turbine honeycombs, alumina-forming for power plant exhaust components.
- Chemical/Petrochem: Haynes 214 plates for chemical waste incinerators, hazardous processing; chlorination resistant Alloy 214 for petrochemical piping, durable sheets in carbon-rich atmospheres.
