What is the UHP Graphite electrode?

Graphite electrode is made of petroleum coke and imported needle coke.

What is the UHP Graphite electrodes? and let us see the specification details 
Graphite electrode is made of petroleum coke and imported needle coke. It is widely used in electric arc furnace and refining furnace. It is suitable for producing alloy steel and other metal and nonmetallic materials. Varieties: ordinary power, high power, quasi ultra-high power (non-national standard), ultra-high power graphite electrode, specification Φ 300- Φ 600, this product has low resistivity, good conductivity and thermal conductivity, good oxidation resistance, strong thermal shock resistance and mechanical vibration resistance, High mechanical strength, high mechanical processing strength and other characteristics.
