6.Features:

·XFD2 is an alloy tool steel with high content of carbon and chrome. After heat treatment, it has very high hardness and abrasion resistance. This steel also features in high hardenability and good dimensional stability. It is suitable for manufacture of clod-work dies and thermoset plastic molding molds which require high precision and long service life.

·Pure steel quality due to vacuum degas refining treatment;

·Crushed crystal structure bonded by forging and rolling; carbonized granules which are fine and even, so that there will be no cracking under quenching;

·For special adding of reinforcing elements molybdenum(Mo) and vanadium(V), both the abrasion resistance and toughness are better than SKD11.
