Material selection is a step in the process of designing any physical object. In the context of product design, the main goal of material selection is to minimize cost while meeting product performance goals. [1] Systematic selection of the best material for a given application begins with properties and costs of candidate materials.
For stainless-steel ConFlat flanges, baking temperatures of 450 °C can be achieved; the temperature is limited by the choice of gasket material. CF flanges are sexless and interchangeable. In North America, flange sizes are given by flange outer diameter in inches, while in Europe and Asia, sizes are given by tube inner diameter in millimeters.
Type C – flexible gasket (high temperature) metal bellows.
