Haynes 230 Plate – Alloy 230 Composition & Key Properties
Haynes 230
Haynes 230 is a nickel-based superalloy built for strength, stability, and corrosion resistance in extreme conditions. It performs reliably in high-heat environments, resisting oxidation and nitridation at temperatures up to 2100°F (1150°C). The alloy is made from a precise mix of nickel, chromium, tungsten, and molybdenum, each playing a clear role in performance. Nickel, forming around 56–66% of the composition, provides toughness and protects against scaling. Chromium enhances oxidation resistance, while tungsten adds strength at elevated temperatures. Molybdenum improves resistance to localized corrosion, and smaller elements like carbon, silicon, and manganese support structural stability. In applications where material failure is unacceptable, Haynes 230 stands out for its controlled chemistry and dependable behavior.

The material properties of Haynes 230 make it a strong choice for high-temperature fabrication. It has a density of 8.96 g/cm³ and a melting point of 1343°C, giving it excellent thermal stability. Machining is straightforward, as standard iron alloy methods can be used. Heavy lubricants and water-based coolants help extend tool life and improve surface finish. The alloy forms well using conventional processes and can be welded with common methods such as GTAW and SMAW. Forging is carried out between 1177°C and 927°C. Cold working is also possible, though softer die materials are preferred. To restore strength after fabrication, annealing is done at 1218°C followed by rapid cooling. Good machinability allows Haynes 230 to fit a wide range of production needs.
Haynes 230 material is governed by standards such as ASTM B435, ASTM B572, and related specifications. These standards ensure consistent quality and predictable performance. In aerospace, the alloy is used for combustion cans, ducts, and turbine components that face constant high heat. It is also used to protect thermocouples in extreme temperature settings. In power generation and industrial processing, Haynes 230 is used in furnace fixtures, hot gas ducting, and cyclone separators where long service life is critical. In chemical processing, it supports grids, heat exchangers, sparger tubes, and recuperators, handling both heat and corrosive media. Across these uses, Haynes 230 proves to be one of the most reliable alloys for demanding systems.
