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
steel. 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.
P20 has good manchanical property After deal with it , it will make
surfece have equal hardness . P20 has nice polishing ,mini
roughness on the surface . P20 /1.2311 can be uesd directly after
the mould machined
