1.2379 / D2 Prehardening Cold Work Special Tool Steel Bar 30mm
Introduction:
Grade 1.2379 / D2 steel is a high wear resistant micro deformation cold working die steel, belonging to air hardening tool steel. With high quality fraction of carbon and high chronic, the hardness can up to 60HRC after heat treatment, but malleability,toughness,rust resistance is not good and the surface of the steel is also difficult to be polished.
Available size(mm):
| Flat Bar Size(mm) | Round bar Size(mm) | |||
| Thickness | Width | Length | Diameter | Length |
| 8-80 | 155-610 | 3000-6000 | 14-80 | 300-6000 |
Chemical Composition(%):
| C | Si | Mn | Cr | Mo | V | P | S |
| 1.40-1.60 | 0.30-0.50 | 0.30-0.50 | 11.0-13.0 | 0.70-1.20 | ≤0.8 | ≤0.030 | ≤0.030 |
Feature:
♦ 1), Good processing, heat treatment size stability.
♦ 2), Excellent machinability.
♦ 3), Excellent dimensional stability when hardened.
♦ 4), After hardening and tempering, the high surface hardness match well with the toughness of the body.
Heat treatment:
| Quenching | Tempering | ||||
| Heating temperature/℃ | Cooling | Hardness/HRC | Heating temperature/℃ | Cooling | Hardness/HRC |
| 980-1040 | Oil or Air | 60-65 | 180-220 | Air | 60-64 |
| 1060-1100 | 60-65 | 510-540 | Air | 60-64 | |
Applications:
For metal stamping die, drawing die, stainless steel sheet punching die, high hardness punching die, cutting knife mold, Roll Die, metal parts production, machinery manufacturing etc.
♦ (1) Used for drawing die of refrigerator compressor rear cover, quenching hardness 56~58HRC.
♦ (2) In order to improve the service life of flat rolling material for D2 cold working die, the wear resistance and impact toughness of steel are greatly improved by adding rare earth, so as to improve the service life of flat rolling material of round die.
♦ (3) Because the content of V and Mo in D2 steel is higher than that of Cr12MoV steel, it has better comprehensive properties, and the traditional Cr12MoV steel will be replaced gradually.
♦ (4) Made of D2 steel rolling wheels, from Taiwan palette die, and Cr12MoV can improve the service life of steel compared to 5 ~6 times.
Advantages:
♦ 1. High wear resistance;
♦ 2. High compressive strength;
♦ 3. Good dimensional stability;
♦ 4. Good machining performance;
♦ 5. Good toughness;
♦ 6. Excellent softening of temper;
Factory Hardness:
Soft Annealing 255HB
Terms of payment:
30% deposit T/T and the balance by L/C at sight, or T/T.
Delivery condition:
For abundant stock, 15-20 days.For customized products, 30-50 days.
With the development of cold stamping products moving towards high accuracy,high efficiency,varieties, we require the mould steel should has good wear resistance and high toughness.
Compared with Cr12MoV steel, this D2 die steel adds Mo,V compositions,changed the steel cast structure, improved the morphology of ledeburite , toughness and wear resistance are better than Cr12MoV steel, improved the service life as well.Because of the yield point and plastic deformation resistance is higher than Cr12MoV steel, so that forging performance and hot molding properties are a little weak than Cr12MoV steel.
