Angle Iron Shear Blades
Precision Angle Shear / Structural Steel Cut-Off Blades: Clean Cut-Off Tools with Zero Distortion
Yuan Li Knife focuses on the R&D and production of angle iron shear blades dedicated to structural steel component fabrication, ironworking steel structures, and multi-function ironworkers.
During the downward cut-off stroke, the two flanges of an angle iron are prone to inward collapse deformation or cross-sectional burrs caused by uneven stress distribution. Yuan Li angle shear blades feature a precision V-shaped cutting edge geometry that guides shear stresses evenly. Under high-speed, single-stroke downward impacts, they achieve square, perpendicular cut faces completely free of twist, deformation, or edge collapse.
Core Manufacturing Advantages of Yuan Li Angle Shears
- Premium Shock-Resistant Specialty Alloy Steels: Selected from 6CrW2Si, Cr12MoV, and high-toughness cold work tool steels, treated through multi-stage vacuum quenching and tempering to maintain a hardness of HRC 56–60, completely preventing edge chipping when shearing heavy-wall angle steel.
- Micron-Level Profile Angle Grinding: Strict control over V-edge symmetry and mounting datum tolerances ensures snug machine seating for fast, effortless alignment.
- Optimized Shear Edge Geometry: A unique progressive shear rake design significantly lowers the required machine tonnage on ironworkers, reducing machine wear and power consumption.

Common Structural Steel Shearing Issues and Solutions
- Cross-Section Distortion / Edge Collapse: Typically caused by a dull cutting edge or excessive blade clearance between upper and lower dies. Yuan Li provides precision-matched blade sets with razor-sharp edges and tight fits, producing perpendicular, smooth cut faces.
- Frequent Micro-Chipping on the Cutting Tip: Usually results from insufficient material toughness or unreleased residual stresses from heat treatment. Yuan Li utilizes secondary cryogenic treatment and multiple high-temperature tempering cycles to dramatically enhance the microscopic impact toughness of the blade tip.
