A study was undertaken into the structure, the texture, the strength, and the creep of the Cr16Ni15Mo3Ti type steel tubes cold-deformed to 20% strain that are used as the fuel element shells for fast-neutron reactors. The tubes were found to have fibrous 111 and 100 textures along their axis. The preferred orientations 011 normal to the radial plane and (011) and (112) normal to the plane tangential to the tube surface were determined. The strength, the creep strength, and the rupture strength proved to be higher along the tube axis. Qualitatively, this is attributed to a specific texture and the grain shape of the material.
