1.What are the characteristics of Hastelloy G30?
Excellent corrosion resistance: It maintains high stability in harsh environments such as sulfuric acid, phosphoric acid, and chloride-containing solutions, effectively resisting pitting, crevice corrosion, and stress corrosion cracking.
Good high-temperature performance: It retains sufficient mechanical strength and oxidation resistance at elevated temperatures (up to approximately 1000°C), making it suitable for high-temperature industrial applications.
Balanced mechanical properties: It has moderate hardness and good ductility, allowing for easy processing through forming, welding, and machining without significant performance degradation.
High chemical stability: The alloy composition (with controlled amounts of nickel, chromium, molybdenum, and trace elements like copper) ensures low reactivity with most corrosive media, reducing material degradation risks.
2. YWhat is the yield strength of Hastelloy G30?
At room temperature (25°C), the minimum yield strength (0.2% offset) is approximately 275 MPa (40,000 psi) for the annealed state.
For cold-worked states, the yield strength can increase to 480 MPa (70,000 psi) or higher, depending on the degree of cold working (e.g., rolling or forging).
3. What is the tensile strength of Hastelloy G30?
In the annealed state (room temperature), the minimum tensile strength is approximately 620 MPa (90,000 psi).
Cold-worked samples can achieve a tensile strength of 860 MPa (125,000 psi) or more, as cold working enhances the alloy's internal structural density and strength.
