Performance Analysis Of Aisi A2 Materials Under High Load Conditions - China

AISI A2 materials is an American standard air-hardening cold work die steel (corresponding to Chinese standard Cr5Mo1V and Japanese standard SKD12).

Its core advantage is the balance between toughness and wear resistance, and it is one of the most widely used steel grades in medium-to-high load cold working conditions.

Under medium-to-high loads (load stress ≥300MPa, with repeated impact/friction/extrusion ), its performance is significantly affected by the heat treatment process and the type of working condition (impact/wear/bending).

Under medium to high load conditions, AISI A2 materials requires standard air quenching + low-temperature tempering treatment.

Its core mechanical properties lay the foundation for its performance under subsequent working conditions.

Specific indicators are as follows: | Performance Indicators | Typical Value (58-60HRC) | Key Significance for Medium to High Load Conditions |

| Hardness | 58-62HRC | Determines basic wear resistance and resists surface plastic deformation |

| Impact Toughness (U-shaped) | 15-25 J/cm² | Resists impact fracture under medium to high loads, superior to Cr12 series |

| Compressive Strength | ≥2500MPa | Capable of withstanding high-pressure loads such as cold extrusion and upsetting |

| Bending Fatigue Strength | ≥800MPa (10⁷ cycles) | Copes with fatigue loads from repeated stamping and bending |

| Wear Resistance | Approximately 2.5 times that of T10 steel | Resists abrasive wear and adhesive wear (core failure modes of cold-working dies) | AISI A2 materials is an "all-rounder" steel for medium-to-high load cold working conditions.

Its core competitiveness lies in the balance between toughness and wear resistance.

It is especially suitable for medium-to-high load scenarios with combined loads (impact + wear), and is one of the preferred materials for cold stamping dies, cold heading dies, and bending dies.
