Material Strength

300 Below’s cryogenic tempering process helps to improve structural stability and integrity of metal and aluminum materials used on general aviation and international commercial aviation assets, yielding greater material strength in aerospace applications.

The residual stresses in aviation 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 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) instead of erratic or differential stress creation, commonly imparted by manufacturing processes.

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.
