Abstract : Three alloys; Type H-11 hot work steel, AM 355 semi-austenitic stainless steel, and 18 NiCoMo (300) mar-aging steel were selected for shear spinning evaluation. The selected materials were purchased, extruded and shear spinning preform blanks machined. Subscale pressure cylinders with 0, 25, 50 and 75 percent reductions were produced and final machining of test specimens started. One pressure vessel was tested to failure. The available results of shear spinning and biaxial burst testing are presented. (Author)
