Heat Treatment
Annealed at temperatures between 982°C (1800°F) and 1149°C (2100°F) for a period of 15 minutes to 1 hour per inch of thickness, followed by air cooling or water quenching. This annealing process helps to restore the alloy’s ductility and reduce any residual stresses from cold working or forming.
Workability
INCOLOY 800H Pipe has good workability and can be formed using a variety of techniques such as cold and hot working, forging, and machining. The alloy has high ductility. Thus, easily welded using common welding techniques such as TIG, MIG, & SAW.
However, due to its high nickel content, INCOLOY 800H Pipe can be difficult to machine & requires special tooling and techniques. Thus, we use low cutting speeds, heavy feed rates, & high coolant pressure to prevent work hardening and cracking.
