MANUFACTURE AND HYDROTEST OF THREE 20 INCH DIAMETER MAR-AGING STEEL PRESSURE VESSELS.

Abstract

The fabrication of three pressure vessels and the hydrotest of two confirms the validity of the design concept and the material selected. The use of 18% nickel mar aging steel strip at a yield strength approaching 300,000 psi is possible in a rocket case. Test results indicate that the processing techniques are practical and that consistency can be obtained. Simplicity of fabrication and heat treatment should be a favorable economic result even though the basic material cost of the mar-aging steel is somewhat higher than the lower alloy steels currently used in rocket motors. It is believed that utilizing the full properties available in the mar-aging steel and the processing techniques developed, that tensile strengths substantially in excess of 300,000 psi are feasible for metal rocket cases.
