1. What are the characteristics of Hastelloy C2000?
Exceptional corrosion resistance: It resists both reducing media (e.g., sulfuric acid, hydrochloric acid) and oxidizing media (e.g., nitric acid, hypochlorite), making it suitable for complex corrosive environments.
Good mechanical properties: It maintains stable strength and ductility over a wide temperature range, from room temperature to high temperatures around 650°C (1200°F).
Excellent weldability and fabricability: It can be welded using common methods (e.g., TIG, MIG) without significant loss of corrosion resistance, and is easy to form via processes like bending and rolling.
Resistance to stress corrosion cracking (SCC): It performs well in chloride-containing environments, a common cause of SCC in many other alloys.
2. What is the yield strength of Hastelloy C2000?
For annealed products (the most common state), the minimum yield strength (0.2% offset) is approximately 275 MPa (40,000 psi) at room temperature.
In some cold-worked states, the yield strength can be significantly higher, reaching up to 550 MPa (80,000 psi) or more, depending on the degree of cold working.
3. What is the tensile strength of Hastelloy C2000?
For annealed products, the minimum tensile strength is approximately 690 MPa (100,000 psi).
The tensile strength of cold-worked products is higher, usually ranging from 860 MPa (125,000 psi) to 1100 MPa (160,000 psi), based on the level of cold working.
