Plastic Prehardened Mould Steel 1.2311 P20 3Cr2Mo Alloy Steel Block For Metal Extrusion Die
1. Comparable Grade
AISI/ASTM | DIN | JIS | GB |
P20 | 1.2311 | PDS-3 | 3Cr2Mo |
2. Application
It's used in zinc, aluminum,magnesium and its alloy die-casting
mould, thermoplastic plastic injection molds, extrusion die,
thermoplastic plastic blow molding mold, overloading mold main
components, and metal extrusion die set.
3. Feature
1. 1.2311 has pure steel vacuum degassing refining process for
polishing or etch processing plastic mold.
2. 1.2311 usually is in pre-hardened state of supply,. Without heat
treatment can be used directly in the mold, so
the construction period is shortened.
3. This steel has good machinability and mirror polishing
properties.
4. Its hardness after prehardening is 28-34HRC.
5. It has good dimensional stability.
4. Chemical composition (%)
C | Si | Mn | P | S | Cr | Mo |
0.28-0.40 | 0.20-0.80 | 0.60-1.00 | ≤0.030 | ≤0.030 | 1.40-2.00 | 0.3-0.55 |
5. Characteristic
1. Vacuum degassing refining processing steel purity, suitable for
polishing or etch processing plastic mold.
2. In pre-harden state delivery, no need in heat ttreatment can be
directly used for mould processing, shorten the construction.
3. After heat treatment machining and polishing performance is good,
the nitriding treatment, can be suitable for chrome plating surface
treatment, such as material is qualitative hardness is uniform
(400mm thick), good toughness and good machining performance.
