Leading Graphite Supplier USA - From stock or custom order.
An increasing proportion of global steel is made using electric arc furnaces, and the electric arc furnace itself is becoming more efficient, making more steel per tonne of electrode. An estimate based on USGS data indicates that graphite electrode consumption was 197,000 tonnes in 2005.

Not All Graphite is the Same. The composition of the graphite can be adjusted to achieve different mechanical, thermal, and electrical characteristics for different applications. Graphene is a highly crystalline graphite used for its excellent electric conductivity. Large grain graphite is commonly used for electrodes in steel production.

Graphite - Wikipedia
Thermodynamically, graphite at atmospheric pressure is the more stable form of carbon. Diamond is trans-formed to graphite above 1500°C (Figure 1-4). The structure of graphite consists of a succession of layers parallel to the basal plane of hexagonally linked carbon atoms. The ideal graphite structure is shown in Figure 1-5.

Industrial electric arc furnace temperatures can be up to 1,800 °C (3,272 °F), while laboratory units can exceed 3,000 °C (5,432 °F). The electric arc furnaces are the most widely used steel furnace around the world. It can be used to smelt high-quality steel and other special steels. Advantages
