How can aerospace components and optical benches benefit from deep cryogenic processing?

The residual stresses in aerospace components are significant due to substantial machining needed to remove mass from the component. Residual stresses may also be caused by machining from end mills, taps, reamers, bores, broaching, and drilling operations. These residual stresses are varied and include three primary types of stress: compressive stress, tensile stress, and hoop stress.

300 Below solves these problems by processing the entire mass of the component part (core AND surface) transitions through a full 600 degree range (-300°F to +300°F) creating stress relief (technically through uniform stress being imparted throughout the three dimensional structure) instead of erratic or differential stress creation, commonly imparted by manufacturing processes.
