The difference between graphite carburizer and coal carburizer 

The difference between graphite carburizer and coal carburizer:

First, the raw materials are different: the graphite carburizer is made of graphite after screening and processing, and the coal carburizer is made of anthracite coal forging;

Second, the characteristics are different: graphite carburizer has low sulfur, low nitrogen, low phosphorus, high temperature resistance, good conductivity, etc., which are advantages that coal carburizing agents do not have;

Third, the absorption rate is different: the absorption rate of the graphite carburizer is more than 90%, which is why the graphite carburizer with a low fixed carbon content (75%) can also meet the requirements of use;

Fourth, graphite carburizer is relatively expensive, but the comprehensive cost of use is low.
