Commercial Aviation

300 Below’s cryogenic tempering process helps to improve aviation components yielding greater strength and stability during flight related aerospace applications.

Residual stresses in components used in aviation 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 aviation 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) thus reducing erratic or non-uniform differential stress being introduced into the molecular structure of a material, as is commonly imparted during manufacturing processes as well as frequent ascent and descent of aviation components (including metal or aluminum structural components) into the upper atmospheres of our planet Earth.

Important note for our aviation industry clients:

300 Below does not process components for U.S. commercial aviation (individual major carrier airlines in the United States of America) due to an excess of trial attorneys operating in the commercial aviation sector wanting to sue every supplier for any reason during mechanical failure related aircraft accidents, but we are willing to help with general aviation (privately owned and operated aircraft) parts and components.
We are able to work directly with companies such as GE, Safran, CFM, Rolls Royce, AirBus, and Boeing so long as our treated parts and components do not end up on the end user aircraft in U.S. commercial aviation. We will gladly process components used during the manufacturing process of U.S. based aircraft, but we are not willing to treat brake rotors and other metals that are directly attached to U.S. commercial aircraft carrying civilian passengers.
