We supply a complete range of industrial slitter blades and shear knives with premium H13K carbon steel substrates, optimized for high-efficiency slitting of steel coils, sheets, and strips. Explore our full range at Slitting Line Knives and Tools and Shear Blades & Knives, including:
Our slitter line blades are forged from high-grade H13K carbon steel and premium alloy steels, a specialized material developed for excellent toughness, wear resistance, and thermal stability. This substrate delivers exceptional performance when slitting:
H13K carbon steel provides balanced hardness and toughness, prevents chipping and breakage during continuous slitting, and ensures consistent cutting performance for long production runs. For more technical details, visit our Production Process page.
We adopt precise vacuum heat treatment and quenching processes for our H13K carbon steel blades, with strict temperature control to achieve optimal hardness (HRC 52-58) and internal stress relief. This process enhances wear resistance, impact resistance, and dimensional stability, making the blades ideal for continuous operation in heavy-duty slitter lines while maintaining cutting edge integrity. Shinite’s independent R&D ensures continuous optimization of heat treatment for H13K steel.
Every Carbon Steel Shear Blade H13K is precision-machined using advanced CNC equipment and surface grinders to achieve tight dimensional tolerances and smooth cutting surfaces. We strictly control outer diameter, inner hole, thickness, and parallelism for perfect fit in slitter line machines. Full customization includes:
Discover our precision capabilities on the Factory VR tour.
We implement a comprehensive quality control system from raw material inspection through forging, heat treatment, precision machining, to final testing. Each blade undergoes hardness testing, dimensional inspection, edge sharpness verification, and trial slitting. This guarantees zero defects, perfect fit in slitter lines, stable performance, and long service life in industrial slitting applications. View our quality commitments at Certificates.
