GH909 Alloy Properties Details GH909 is a Nikkle-based inert alloy that exhibits excellent creep and oxidation resistance and is thermally stable over a temperature range of 650-1100. Specifically, the main physical property parameters of GH909 alloy are as follows: density: whether at room temperature or high temperature, the density of GH909 is 82 g cm3 or so. Melting Point: GH909 has a high melting point of 1310, which shows its ability to operate for long periods of time in high-temperature environments. Hardness: GH909 has a hardness of about 370 HB at room temperature. At high temperatures, its hardness remains high at 300-320 HB. This means that GH909 can retain its mechanical properties over a wide range of temperatures. Tensile strength: At 20 and 1000 °C, the isothermal tensile strength of GH909 can reach 1120 MPa and 350 MPa respectively. GH909 superalloy chemical composition
