Material Description
The Nickel-Chromium-Iron-Molybdenum alloy is the so-called AMCP HX, and is developed in mid-19th century, and the mechanical properties of this alloy developed quite a lot during the past hundreds of years. Currently, HX is mainly applied in high temperature, and is famous for its anti-corrosion properties in many circumstances. Because of its resistance to corrosion and its high temperature strength HX is used for power station parts, turbine engine components or furnace parts. In a corrosive environment, this alloy can be used up to 1200 °C for static components, while creep strength is given up to 850 °C. The data in this sheet is based on the wrought material and laser processing with 40μm as layer thickness EOS M280. The built parts can be heat-treated, and material properties will vary in a specific range. And the parts can be machined, spark-eroded, polished, coated and/or any other post-treatment needed.
