Blade Blank Material Selection and Pre-treatment

‌Mainstream Materials‌

‌Medium-to-High Carbon Alloy Steel‌ (e.g., NM360-NM600 wear-resistant steel): Requires forging or rolling to achieve uniform grain structure, with hardness exceeding 46 HRC.

‌Special Condition Materials‌: Boron steel (30MnB5) for high-impact environments; ultra-low-temperature wear-resistant steel for cryogenic conditions.

‌Blank Types‌

‌Forgings: Suitable for high-strength cutting plates. Die forgings offer high precision (allowance ≤3mm), while open-die forgings are used for single-piece or small-batch production.

‌Castings: Cast steel components can be used for complex-structured cutting plates, but subsequent heat treatment is required to eliminate internal stresses.
