アイテック Product Lineup

"Hastelloy" is excellent in heat resistance, corrosion resistance, oxidation resistance, and high-temperature properties, and is used in fields such as aerospace, space, and nuclear power. The reasons it is difficult to machine include high-temperature strength, susceptibility to work hardening, high affinity with tool materials, and poor thermal conductivity. Choosing the right tools is challenging, and machining requires utmost care, making it a material that is particularly difficult to work with among hard-to-machine materials. 【Features】 ■ Excellent heat resistance, corrosion resistance, oxidation resistance, and high-temperature properties ■ Used in fields such as aerospace, space, and nuclear power *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a processing case of "thin plate polishing" conducted at Aitec Co., Ltd. This case involves a Hastelloy (C-22) plate measuring 3×305×355, with a thickness tolerance of ±0.02mm and geometric tolerances for flatness and parallelism within 0.03mm. The processing was done through surface grinding, repeatedly polishing one side. Unlike conventional clamping methods, we used a different clamping technique to finish the reference surface, and then clamped the opposite side to prevent the workpiece from warping during finishing. [Case Overview] ■ Material: Hastelloy ■ Size: 3×305×355 ■ Processing Details: Surface Grinding *For more details, please refer to the PDF document or feel free to contact us.
