BS ISO 5832-12:2019 pdf free.Implants for surgery一Metallic materials.
1 Scope This document specifies the requirements for two wrought cobalt 28-chromium 6-molybdenum alloys used for surgical implants. The properties apply specifically to wrought bar, rod and wire. NOTE 1 The mechanical properties of a sample obtained from a finished product made of this alloy can differ from those specified in this document. NOTE2 The high carbon content of this alloy produces a structure containing a significant carbide distribution. This can be adjusted either in the production of the bar or in subsequent thermomechanical processing to produce the final device. Carbide distribution in the final device is not included as part of this document. 2 Normative references.The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
