Mold Steels are specialty grades of tool steel that are more well-suited to be used in mold applications. Mold steels are manufactured to be a homogeneous material that yield high cleanliness levels and free of most undesirable elements. The beneficial characteristics of these grades are good polishability and distinctive texturing.
Mold Steel Grades:
P20 – P20 High Hard
P20 Mold Steel
P20 is a low-alloy tool steel typically used for plastic injection mold cavities and die casting dies. P20 is typically sold in a pre-hard condition with a 28-32 on the Rockwell C Scale.
P20 High Hard (HH) Mold Steel (A.K.A. P20HH)
P20 high hard is an improved P20 with a 34-38 on the Rockwell C Scale. It is typically better for compressive strength than normal P20.
