1.2311/ P20/ PDS-3 Hot Rolled Plastic Mold Steel Plate Used for
Injection Mold
1.2311 P20 3Cr2Mo is a common alloy tool steel which usually
supplied in QT condition. The 1.2311 steel can give an excellent
polished finish and wear resistance.
Applications
Used for various lager-sized or medium-size precision plastic mould
and alloy parts.
a, Ideally suited for the production of plastic moulds;
b, Die holders, zinc die casting dies, backers, bolsters and
injection moulds;
c, Shafts, rails and wear strips;
