In a sprawling nitric acid plant in Tamil Nadu, a failing transition duct in the gas turbine led to unplanned downtime costing ₹5 crore, as Hastelloy X cracked under 1000°C creep loads. Switching to Haynes® 230 Plates (UNS N06230), with 65,000-hour rupture life at 871°C/103 MPa, extended component life 10x, per Larson-Miller data. Procurement engineers sourced ASTM B435 plates from Aurico Alloys LLP, optimizing uptime and slashing costs in power and chemical ops.
Table of Contents:
Haynes® 230 plates lead in chemical, oil & gas, marine, pharma, and power industries for balanced high-temp strength, oxidation, and nitriding resistance up to 1150°C. This Ni-Cr-W-Mo alloy (2.4733) outperforms in combustion cans, transition ducts, and flame holders, where solid-solution strengthening delivers superior thermal stability.
Choose Haynes 230 over Hastelloy X for 4-10x longer creep life (e.g., 65,000 vs 5,000 hrs at 871°C) and better fabricability, enabling 75% thinner sections without strength loss vital for OEMs and fabricators. Nitriding-resistant plates suit ammonia burners; exporters serve global nitric acid plants.

Applications & Benefits
Why this grade
Haynes® 230 is a nickel-chromium-tungsten-molybdenum alloy with a lanthanum addition. It is the all-round choice in the range, combining creep strength and oxidation resistance to about 1150°C with the thermal stability and fabricability that older alloys such as Hastelloy X do not have, plus useful resistance to nitriding atmospheres.
