JIEBAO Alloy and Steels stocks and supplies 1.2311 Plastic Mould Steel. This grade of tool steel is also known as P20 Plastic Mould Steel.
P20 is an alloy tool steel with good machining ability even when hardened and tempered (Brinell 300). This steel has a polished surface and is one of the most regularly used requirements for machine cut plastic molds and casting dies. P20 die steel is a kind of mold welding material model, the earliest is P20, followed by P20H, P20Ni have come out. P20 steel is suitable for making plastic molds
| 1.P20+Ni is upgrade version of plastic mold steel 0f 2311, which normally supplied in Prehardened condition |
| 2.Hardness in supplied condition is 280-320 HB |
| 3.Additional nickel content of 1 % increases through hardening |
| 4.It is micro-alloyed |

Heat Treatment
During the carburizing process, P20 / DIN 2311 / AISI P20 tool steels are heated to 871-899°C (1600-1650°F) in the carburizing medium. After carburizing, these steels are heated to 816-871°C (1500-1600°F) to harden, then held for 15 minutes before being oil quenched.
Hardening:
Heat the steel consistently to 820-840°C until completely heated. Soak in oil to cool.
Forging:
Heat gently, giving the steel enough time to heat all the way through. start forging at 1050 degrees. Never forge below 930°C, reheating as needed. After forging, allow it to progressively cool.
Stress Relieving:
To reduce machining stresses when dies are substantially machined, stabilizing is advised right before finishing machining. 460° to 500° Celsius. Good soaking followed by air cooling is advised.
Normalizing:
Heating uniformly to 900°C for P20 / DIN 2311 / AISI P20 steel.
Annealing:
Heating consistently to 770-790°C for P20 / DIN 2311 / AISI P20 annealing. Good soaking, gentle cooling in the boiler.
Tempering:
Heat evenly and soak for at least one hour for every 25mm of section at the tempering temperature. Allow it to cool in a cool air.
Welding:
P20 / DIN 2311 / AISI P20 tool steels are welded using traditional techniques.
