Product Overview

Haynes 230, a domestically produced high-performance nickel-chromium-wolfram-molybdenum solid solution strengthened deforming high-temperature alloy, is made by combining a pure nickel matrix with a high-chromium, tungsten, and molybdenum multi-element solid solution strengthening design. This alloy features ultra-high tissue stability, resistance to thermal fatigue, and super-high temperature oxidation resistance, making it one of the most balanced commercial nickel-based solid solution alloys at the 1000℃ level. Its performance is significantly superior to GH3536 (Hastelloy X), with prominent advantages in high-temperature strength, resistance to thermal fatigue, and high-temperature oxidation resistance. It is non-magnetic, with excellent welding and forming processes, and is a core high-end heat-resistant material for aviation, energy, and ultra-high temperature industrial furnaces.

Main Product Features

• High-temperature stability and high thermal strength: Utilizing tungsten and molybdenum composite solid solution strengthening mechanism, the matrix structure is highly stable, maintaining mechanical strength and structural integrity under long-term ultra-high temperature conditions of 1000℃.

• Top-grade high-temperature oxidation and heat corrosion resistance: The alloy contains a 22% high-chromium ratio, which can generate a dense, self-repairing, and highly stable chromium oxide protective layer at high temperatures.

• Excellent thermal fatigue resistance and structural reliability: The alloy has uniform grain structure, low and stable coefficient of thermal expansion, and boasts top industry thermal fatigue and thermal shock resistance.

• Excellent processing, forming, and welding properties: good plasticity in the solid solution state, stable welding performance, and high consistency in component forming.
