The carbide steel material for mold parts is very hard and can reach HRA90 and above, which is unmatched by most other metal materials. This gives tungsten steel an unrivaled advantage in applications requiring high strength and hardness.
Carbide steel also has very good wear resistance. This is because the carbide particles in tungsten steel can form a hardened layer during wear, which increases the wear resistance of the material. This gives tungsten steel an advantage in applications that require wear resistance.
In addition Carbide steel is difficult to machine, this is due to the high hardness of tungsten steel, which makes it susceptible to tool wear and cutting heat during machining.
