P20/1.2311 is a general purpose mold steel designed for the plastic
mold industry. With a combination of Chromium, Manganese,
Molybdenum, and Carbon, as well as being pre-hardened, P20 is a
very popular mold steel grade.
P20/1.2311 is used for plastic injection and compression molds, and
zinc die casting dies. Molds from this material can be made and
placed directly into service.
P20/1.2311 has a machinability rating of 65% of a 1% carbon tool
P20/1.2311 is sold in the pre-hardened condition. Typical annealed
hardness is BHN 286/301 RC 30/32.
P20/1.2311 maximum working hardness is BHN 301 RC 32. (Further heat
treating is not normally required. )
P20/1.2311 is capable of meeting ASTM-A681.
