1. Introduction to GH4202 Materials<\/span><\/strong><\/p>\n

\u00a0 \u00a0 \u00a0 GH4202 is a Ni-Cr-based precipitation hardened deformation high-temperature alloy with a temperature of -253-800 degrees Celsius. The alloy is added with tungsten and molybdenum elements for solid solution strengthening, aluminum and titanium elements are added to form an aging reinforced phase, and a small amount of boron and cerium elements are added to purify and strengthen the grain boundaries. The alloy has good comprehensive mechanical properties and stable structure. The alloy has high corrosion resistance and oxidation resistance, as well as good oxygen-rich corrosion resistance. This alloy is a typical multi-purpose high temperature alloy material.<\/span><\/p>\n
