Key Product Advantages of Our H13k Shear Knives 52 Shear Blades

1. Premium H13k Alloy Steel Material & Stable HRC 52 Hardness

Our H13k Shear Knives 52 Shear Blades are forged from high-grade H13k (4Cr5MoSiV1) alloy tool steel, a specialized material for high-temperature and heavy-impact shearing. With strict heat treatment, we achieve stable HRC 52 hardness, delivering exceptional performance when cutting:

• Carbon steel, mild steel and high-tensile steel plates
• Rebar, deformed steel bars and iron rods
• Steel coils, sheets and profiles for rolling mills
• Scrap metal and industrial metal waste for recycling
• Thick metal materials requiring high impact resistance

H13k material provides excellent toughness, thermal stability and impact resistance, preventing chipping and breakage during heavy shearing operations. For more technical details, visit our Production Process page.

2. Advanced Precision Heat Treatment Technology

We adopt vacuum quenching and tempering heat treatment processes to ensure uniform hardness distribution (HRC 52) across the entire blade. This professional treatment enhances the blade's wear resistance, impact toughness and dimensional stability, making our H13k Shear Knives ideal for continuous heavy-duty shearing in hydraulic shears, flying shears and rolling mill equipment. Shinite’s independent R&D ensures stable and reliable material performance.

3. High-Precision Machining & Customized Dimensions

Every H13k Shear Knife 52 Shear Blade is processed by advanced CNC machining centers, surface grinders and wire-cutting machines to ensure precise dimensional tolerance. We strictly control blade geometry, mounting hole positions and edge sharpness. Full customization includes:

• Custom length, width and thickness according to customer drawings
• Precise mounting hole positions and diameters for perfect equipment fit
• Optimized edge angles for different metal shearing applications
• Smooth machined surface to reduce material adhesion
• One-piece, laminated or segmented designs for various shear machines

4. Rigorous Multi-Stage Quality Control

We implement a full-chain quality control system from raw material inspection, forging, heat treatment, precision machining to final testing. Each blade undergoes hardness testing, dimensional inspection, impact resistance testing and trial cutting verification. This guarantees zero defects, stable HRC 52 hardness, perfect fit and reliable performance in your shearing equipment. View our quality commitments at Certificates.
