P-20 is a general purpose mold steel designed for the plastic mold industry. With a combination of Chromium, Manganese, Molybdenum, and Carbon, unwell as being pre-hardened. P-20 is a very popular mold steel grade. P-20 is used for plastic injection and compression molds, and zinc die casting dies. How To Choose Material For Injection Molds, S7, P20, NAK P20 is the old standard pre-hard steel, and it is still quite popular. It does have a tendency to work harden and contain hard spots, but, with carbide tooling so commonly used, this is not much of an issue. It is approximately 32 Rockwell and is easy to weld and polish. Aluminum is used more often now that mold grade alloys have been developed.
