Nimonic 75 Plates | UNS N06075 Furnace & Turbine Workhorse
Table of Contents:
When a Tata Steel furnace muffle failed after 18 months at 1050°C causing ₹4.2 crore production losses from molten metal contamination due to Inconel 600 oxide spalling maintenance switched to Nimonic 75 Plates, extending service life to 8+ years with 3x better chromium oxide adherence that resists sulfur/salt attack in carburizing atmospheres. Industrial furnace engineers, gas turbine OEMs, petrochemical procurement heads, and heat treatment fabricators now specify these 80/20 nickel-chromium plates (UNS N06075) where 600, RA330, or HK stainless suffer scaling and carburization above 950°C.
Nimonic 75 maintains 750 MPa tensile and 275 MPa yield at 1000°C with oxidation rates <0.2 mg/cm²/hr versus Inconel 600's 0.8 mg/cm²/hr in cyclic 20% O₂ + 5% SO₂ Ti/C additions form stable spinels that self-heal during thermal shock unlike simple Cr₂O₃ scales. The balanced 20% Cr prevents sigma phase embrittlement that weakens 330/800H above 900°C while retaining 40% elongation for fabrication.

Applications & Benefits
Why this grade
Nimonic 75 is an 80/20 nickel-chromium alloy with titanium stabilisation, and it is solid-solution strengthened only — it cannot be significantly age-hardened. That is precisely why it is chosen: it forms and welds readily with no solution-treat-and-age cycle and no strain-age cracking risk, which makes it the sheet-metal grade for gas turbine combustion hardware, furnace parts and heat-treatment fixtures.
- Furnaces: UNS N06075 nickel alloy plates for land-based turbine exhaust systems; resists carburization better than 600.
- Chemical: Nimonic 75 plates for sulfuric acid reactors and high-heat chemical process vessels; high-purity Nimonic 75 plates for pharmaceutical sterilization.
- Petrochem: Corrosion resistant Alloy 75 plate stockist in Mumbai for petrochemical waste heat recovery.
- Marine/Oil: Marine grade Nimonic 75 plates for offshore platform flare tips; scaling resistant Nimonic 75 sheets.
- Sourcing: Verified Nimonic 75 plate exporters in India with MTC EN 10204 3.1 certification; custom cut for laboratory equipment.
