Production of Inconel 718 Mortar Tubes by Hydrostatic Extrusion

Abstract

Inconel 718 Hydrostatic Extrusion ,. D 20 ABSTRACT (Continue oan trverse ide It necos*=-and Identify by block m.mitsee Because of a desire to :educe the cost of producing mortar tubes from a nickel alloy (Inconel 718), hydrostatic extrusion was examined at Batteile, Columbus Laboratories. Using subscale tubes, extrusion parameters were developed ana then applied to full size 60rnm tubes. It was shown that tubes can be satisfactorily produced at a reduced cost. Estimates were developed to mass produce hydrostatically extri-ded tubes. The processing parameters, dimensional results and economic analysis are presented in detail.
