Key Product Advantages of Our H13 Steel Shear Blades Hrc 65 for Rolling Mill Slitting Machine Plate

1. Premium H13 Alloy Steel Material & HRC 65 High Hardness

Our shear blades are forged from high-quality imported H13 hot work alloy steel, a professional grade known for excellent toughness, impact resistance and thermal stability. Through precise heat treatment, we achieve a stable and uniform hardness of HRC 65, making these blades ideal for heavy-duty slitting and shearing of:

• Carbon steel plates and hot-rolled steel strips
• Thick metal sheets for rolling mill production lines
• Alloy steel plates and structural steel materials
• High-strength metal strips requiring continuous slitting

The H13 substrate ensures exceptional resistance to breakage and chipping even under high-pressure slitting conditions, while HRC 65 hardness delivers outstanding wear resistance and long-term cutting stability. For more technical details, visit our Production Process page.

2. Precision Heat Treatment & Stable Performance

We adopt vacuum quenching, multiple tempering and cryogenic treatment processes to eliminate internal stress and ensure uniform hardness distribution across the entire blade. This advanced heat treatment technology endows our H13 steel shear blades with high toughness, excellent impact resistance, minimal deformation and long service life — perfectly matching the high-load, continuous working requirements of rolling mill slitting machines. Strict quality control ensures consistent hardness and stable performance in every batch.

3. High-Precision Machining & Perfect Cutting Fit

Every H13 Steel Shear Blade is processed by advanced CNC machining centers, precision grinders and profile grinding equipment to ensure strict dimensional accuracy. We control parallelism, flatness, edge straightness and mounting hole positions to micron-level tolerance. Full customization includes:

• Custom blade dimensions (diameter, thickness, length as per drawings)
• Precise mounting hole positions and sizes for rolling mill equipment
• Optimized edge geometry for smooth slitting and reduced burrs
• Fine ground surface finish for smooth material feeding
• Integral forged or assembled designs for different slitting machines

4. Strict Quality Inspection & Long Service Life

Our H13 steel shear blades undergo full-process quality inspection from raw material testing, forging, heat treatment, precision machining to final finished product inspection. Each blade is tested for hardness uniformity, dimensional accuracy, edge sharpness, impact resistance and assembly fit. This guarantees zero defects, stable performance, long service life and reliable operation in rolling mill slitting machines. View our quality commitments at Certificates.
