Graphite electrode UHP

Excellent resistance to oxidation, hign resistance to thermal and mechanical stock, high mechanical strength

1.Introduction: 

The graphite electrode is made of high-grade petroleum coke and imported needle coke, and it is widely used in electrical ark furnace for the producing of alloy steel and other metallic or nonmetallic materials. Our products include RP&HP&UHP graphite electrode and anode, the Dia. Is 50-500mm. These products have the advantage of low specific resistance, high electric and thermal conductivity, and excellent resistance to oxidation, high resistance to thermal and mechanical shock, high mechanical strength and high machining accuracy. 

We can supply high quality  product  according to the customer’s requirement.
