Using DC53 (Cr8W2vSi) steel for shear blade ensures exceptional performance. When quenched at 1040°C and tempered at 520–530°C, it consistently maintains a hardness of HRC 62–63. This effectively overcomes the common issues found in Cr12MoV, such as insufficient hardness after high-temperature tempering and poor toughness.

Key Advantages:
Superior Machinability: Offers excellent cutting and grinding properties.

Structural Integrity: Eliminates the risk of cracking during Wire EDM (Electrical Discharge Machining) processing.

Dimensional Stability: After tempering, retained austenite is almost completely transformed, rendering cryogenic treatment virtually unnecessary.

Optimized Microstructure: When tempered at a low temperature of 200°C, carbides are distributed uniformly without the presence of massive carbides, resulting in outstanding toughness.
