3.Characteristics:
1.High hardenability and high toughness;
2.Excellent thermal cracking ability, in the workplace can be water-cooled;
3.Moderate wear resistance ability, but also a carburizing or nitriding process can be used to improve its
surface hardness, but slightly to reduce thermal cracking ability;
4.Since its low carbon content, tempering in the secondary hardening ability is poor;
5.The ability to resist softening under high temperature, but using a temperature higher than 540 ℃ (1000 ℉)
hardness appears rapid decline (that is, the ability of working temperature is 540 ℃). 6.Heat treatment deformation;
7.Medium and high cutting processability;
8.Decarburization of medium.
4.Applications
Can be used for forging hammer forging die, die casting, aluminum alloy hot extrusion die, high-speed
precision forging die and die forging press.
