Abstract Trent 10max tubing of type 316L welded stainless steel is electropolished to a surface smoothness of 10 μin. (0.25 μm) Ra. Trent 15max is electropolished to 15 μin. (0.38 μm) Ra surface smoothness. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on forming and surface treatment. Filing Code: SS-938. Producer or source: Crucible Trent Tube.

The effect of initial waviness on the wrinkling of faces in sandwich construction is studied. Formulae are derived to determine the failing stress when the faces wrinkle due to failure of the core in tension, compression or shear. The importance of core strength requirements in maintaining surface smoothness is noted. A comparison of theory with experiments is made, and the agreement between the two is found to be reasonably good.A sandwich construction consists of two thin face layers of high-strength material and a thick core layer of lightweight material. The function of the core is twofold. Firstly, it increases the bending rigidity of the faces and second, it stabilises them so that they will not wrinkle until high stress is reached.

Alumina substrates of Al2O3–MgO–Cr2O3give excellent surface smoothness. These were studied with respect to their green tapes, the surface finish of fired substrates, and in particular smoothness. The factors contributing to these characteristics were investigated, in particular the effect of the addition of Cr2O3on surface smoothness.
