Super alloy HAYNES(r) 556 alloy has good strength and carburization and oxidation resistance at elevated temperatures. It also has excellent welding and forming characteristics.
Fabrication and Heat Treatment
HAYNES(r) 556 alloy™ can be machined using conventional techniques employed for iron based alloys. High speed operations like milling, grinding or turning can be performed using water-base coolants. Heavy lubricants are recommended for operations such as boring, broaching, tapping or drilling.
HAYNES(r) 556 alloy can be formed by conventional means. For cold forming this alloy, heavy-duty lubricants can be used.
Welding of HAYNES(r) 556 alloy is performed through commonly used welding techniques like gas tungsten arc welding, shielded metal-arc welding, metal-arc welding and submerged-arc welding. However, an alloy filler metal that suits this alloy should be used.
HAYNES(r) 556 alloy can be forged at temperatures ranging from 927 to 1177°C (1700 to 2150°F).
HAYNES(r) 556 alloy can be cold worked using standard tooling methods. As plain carbon steels has an ability to produce galling, they are not preferred for forming this alloy. Galling can be minimized with the help of soft die materials.
HAYNES(r) 556 alloy can be annealed at 1177°C (2150°F) followed by rapid cooling of air and water quenching.
HAYNES(r) 556 alloy can be hardened by cold working.
The following are the major applications of HAYNES(r) 556 alloy:
- Gas turbines
- Heat transfer systems
