Hastelloy C-276 (N10276) Physical Properties:
- Relative density 8.9g/cm3.
- Melting point 1025-17℃.
Hastelloy C276 Sheet Heat Treatment
- Annealing: ASME SB 575 UNS N10276 annealing temperature ranges from 1040°C (1900°F) to 1150°C (2100°F) followed by rapid quenching to room temperature.
- Solution Annealing: Solution annealing can be performed at a higher temperature (about 1175°C (2150°F)) followed by rapid cooling.
- Stress relief: When 2.4819 material is welded or formed, stress relief at around 760°C (1400°F) can reduce residual stress and enhance the dimensional stability of the material.
Machining ASTM B575 Hastelloy C276
Due to the toughness and work hardening tendency of nickel c276 plate, it is necessary to select suitable cutting tools: carbide cutting tools. The process needs to be slow and add coolant, etc.
ASTM B575 (C276) Hastelloy Hot forming
C-276 alloy hot forming is quenched immediately at 1150℃ and quenched with tap water. Cold deformation of C276 alloy will increase its compressive strength.
Suppliers Welding process
Such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), arc welding or other welding processes.
