MATERIAL SELECTION FOR MECHANICAL SEALS

companies in the carbon manufacturing business, the list is fairly small. Resin Impregnated Carbon As the name implies, resin impregnated carbon is a mixture of amorphous carbon/graphite that has been impregnated with a thermoset resin. This is by far the most common type of carbon for mechanical seals used in industry today. While there is a wide

Carbon and Low Alloy Steel Casting Mechanical Properties

Carbon content and heat treatment influence strength and ductility; shown in Figure 1. Carbon contents are typically kept well below 0.30% to avoid problems with cracks in heat treating or welding. The relationship between the ratio of stress to strain is the elastic modulus. Data is derived from a tensile test. The
