GH2132 is a high-temperature alloy based on iron-nickel, strengthened by age-hardening through the addition of titanium and aluminum to form the γ' phase. It exhibits excellent comprehensive properties in the temperature range of 650°C to 700°C, including high strength, good oxidation and corrosion resistance, and good machinability and weldability. Due to its relatively lower cost compared to nickel-based alloys, it is widely used in the aerospace and energy fields.
I. Physical and Mechanical Properties
Physical Properties (Room Temperature): Density: approx. 7.93 g/cm³, Melting Point: approx. 1364-1424 °C
Mechanical Properties (Typical Values, After Standard Heat Treatment):
GH2132 is typically treated with a solution treatment followed by aging treatment.
Standard Heat Treatment:
Solution Treatment: 980-1000°C, holding for 1-2 hours, oil or water cooling.
Aging Treatment: 700-720°C, holding for 12-16 hours, air cooling.
Room temperature mechanical properties: Tensile strength (σb): ≥ 900 MPa
Yield strength (σ0.2): ≥ 600 MPa, Elongation (δ5): ≥ 15%, Hardness: ≤ HRC 35 High temperature mechanical properties (e.g., at 650°C):
Tensile strength: Remains at a high level (approximately 700-800 MPa).
Creation strength: At 650°C and 530 MPa stress, crease life is typically required to be greater than 100 hours.
