Hot Rolled Alloy Steel O1 / 1.2510 / SKS3 For Shape Complexed Cold Die
Introduction:
The characteristics of hot rolled alloy steel O1 / 1.2510 is German microdeformation resistant oil steel, which is high quality and non-deformation cold tool steel.The steel is a good oil quenching cold work die steel, has a good impact toughness, temper softening resistance, mechanical processing performance, firm mouth keep ability, high compressive strength, heat treatment deformation is small.

Feature:
(1) With excellent machinability, hardened, the size is extremely stable, hardened, the surface has a very high hardness.
(2) With a high toughness, so excellent anti-wear ability and easy forging and quenching.
(3) Can be widely used in cutting, cold stamping and forming tools; such as notch die, cold stamping die, various gauges, reamers, mold bushings and plastic small modules.
Applications:
| 1, | It is suitable for making cold-resistant and non-deformed cold mold, such as sheet stamping die and jewelry embossing die. |
| 2, | It is mainly used for various kinds of metal stamping die and forming tools, such as shearing knife die and shaft sleeve. |
| 3, | Cutting tools, woodworking cutting tools, etc. |
| 4, | It can be widely used for cutting tools. |
| 5, | Wear and wear plastic molding mould and plastic small die etc. |
Terms of payment:
30% deposit T/T and the balance by L/C at sight, or T/T.
Delivery condition:
1) EF or ESR, hot rolled or forged, black surface or milling.
2) For abundant stock, 15-20 days.For customized products, 30-50 days.
When hardening, the dimension is extremely stable, after hardening, the surface hardness and toughness are extremely high, with high wear resistance, forging and quenching performance are good.
To prevent grinding crack and surface softening, it is necessary to pay attention to the proper cooling, proper grinding pressure and reasonable machining process to prevent grinding cracks and surface softening.
If mold edm after quenching and tempering, in the final stages of edm, should take the small current high frequency, the mold surface should be after discharge grinding removal "spark white layer", and add a tempering, the tempering temperature about 25 ℃ less than before.
