SUPERIOR IN STEEL PRODUCTION AND MACHINING OPERATIONS
HASTELLOY
Hastelloy contains the significant resisting properties to reducing environments like sulfuric, phosphoric, and acetic acids and hydrogen chloride gas.
Hastelloy is one of the high-performance alloys that are greatly applied to inert and vacuum atmospheres that are exposed to aluminum chloride catalysts, hydrochloric acid, and reducing chemicals. Some of the industries where Hastelloy is applied are mostly exposed to phosphoric, sulfuric, acetic, and hydrochloric acids.
Thus, Hastelloy is suitably used in high-heat applications. This type of high-performance nickel alloy can offer exceptional creep-and-stress rupture and good casting attributes.
Hastelloys have its great machinability properties which include:
- Use of plenty cutting fluid
- Machine in cast and wrought forms
- High-speed steels cutting speeds
- Cut at low speeds
- Grind high-speed cutting tools in turning and lathe operations
Applications:
- Metallurgical industry
- Chemical process industry
- High-speed steels cutting speeds
- Cut at low speeds
- Jet components:
- aircraft nozzle vanes
- tail cones
- engine parts
- cabin heaters
- collector rings
For workability, hastelloy is being annealed to produce ideal characteristics for fabricating sheets.
