FORGE-BUSH
ETERNAL
Cr5MO1V/A2 die steel ( AISI/SAE A2, ASTM A681 standard, corresponding to GB/T Cr5Mo1V, JIS SKD12, W-Nr. 1.2363,Swedish XW-10,) is a classic medium alloy air quenched die steel, known for its balance of strength and toughness and air quenched micro deformation.
Cr5MO1V Chemical Composition
| C | Si | Mn | Cr | Mo | V | P/S |
| 0.95%~1.05% | 0.2%~0.4% | 0.45%~0.75% | 4.75%~5.5% | 0.9%~1.4% | 0.15%-0.5% | ≤0.025% |
Cr5MO1V Heat Treatment
Annealing: 800-850 ℃ slow cooling, spherical annealing hardness ≤230 HB.
Hardening: 940-960 ℃ air-cooled / oil-cooled, air hardening deformation is only 1/4 of manganese oil hardened steel.
Refractory:
Low temperature (180-220 ℃): 60-64 HRC, high wear resistance.
Medium temperature (510-520 °C): 57-60 HRC, better toughness.
Good toughness, effective hardening section≤50mm
Cr5MO1V Mechanical Property
Tensile strength: ≥ 2300 MPa
Yield strength: ≥ 1700 MPa
Elongation rate: ≥ 8%
Impact toughness: superior to Cr12 and 9Mn2V, with strong resistance to cracking.
Feature
Air quenching micro deformation: It can be quenched and hardened by air cooling, and the deformation after heat treatment is much smaller than 9Mn2V and CrWMn, with stable dimensions.
Good toughness: The toughness is significantly better than that of Cr12 and Cr12MoV, and it is less prone to corner cracking and cracking.
Moderate wear resistance: more wear-resistant than ordinary carbon tool steel and 9Mn2V, suitable for medium load molds.
High hardenability: even thicker sections can be hardened as a whole, with strong versatility.
Polished and grindable: with good surface quality, suitable for precision molds.
Application
Cold stamping die, precision stamping die, and blanking die (for medium and thin plate stamping)
Forming die, bending die, stretching die
Wire rolling die, wire rolling plate, scissor blade, punch
High precision, complex shaped, and non deformable cold work molds
