Grade Encyclopedia
What is a grade?
A grade is the model spec of a carbon product: letters for power level or material series, numbers for size. E.g. UHP600 = Ultra High Power graphite electrode, 600mm diameter. Choosing the right grade when posting products or RFQs helps both sides match precisely.
59 grades in total; equivalent grades are for reference only, not official data. Click a grade to view details and related products.
