Introduction:
Grade 1.2311 / P20 / 3Cr2Mo is an internationally widely used plastic mold steel, its good mechanical properties, high hardenability can make Larger cross-section steel to obtain more uniform hardness, and this steel has good polishing performance and high mold surface finish.
When using this steel mold, usually make quenching and tempering treatment first that the hardness is HRC28 ~ 35 (pre-hardened), and then by cold working manufactured molds can be used directly.
Chemical composition(%):
Grade | C | Si | Mn | S | P | Cr | Mo |
1.2311 | 0.35-0.45 | 0.20-0.40 | 1.30-1.60 | ≤0.030 | ≤0.030 | 1.80-2.10 | 0.15-0.25 |
P20 | 0.28-0.40 | 0.20-0.80 | 0.60-1.00 | ≤0.030 | ≤0.030 | 1.4-2.00 | 0.30-0.55 |
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: 285-330HB(28-32HRC);
• 7, Good dimensional stability;
• 8, With long service life,Mold die life up to 50W times.
