SHP Graphite Eletrodes

SHP Graphite EletrodesOur SHP graphite electrodes are manufactured using the same high quality processes as our UHP products. To provide a product that can be used more cost effectively in LMF applications, some of the raw materials in SHP graphite electrodes are of a slightly lower grade. While the consumption rate is a bit higher than that of UHP graphite electrodes, their lower cost tends to offset the difference without an impact on operational functionality.
