Product Description

1.2311 P20 Hot Rolled Steel Flat Bar 

1. Comparable Grade:

AISI/ASTM	DIN	JIS	GB
P20	1.2311	PDS-3	3Cr2Mo

2. Application:
1. Used in zinc, aluminum,magnesium and its alloy die-casting mould.
2. Thermoplastic plastic injection molds,extrusion die.
3. Thermoplastic plastic blow molding mold.
4. Overloading mold main components.
5. Metal extrusion die die set.

3. Feature:
1. Pure steel vacuum degassing refining process for polishing or etch processing plastic mold
2. Pre-hardened state of supply, without heat treatment can be used directly in the mold, shorten the construction period.
3. By forging rolling processing, compact structure, 100% ultrasonic testing, non-porous, needle defects.
4. For the production of plastic mold and die casting low melting point metal mold material.
5. This steel has good machinability and mirror polishing properties.
6. Hardness:28-32HRC
7. Good dimensional stability
8. With long service life,Mold die life up to 50W times

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 of 1.2311 steel flat bar:
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.
