Scrap Shear Blade
-
Scrap Shear Blades for Heavy Steel Sections:
Each scrap shear blade is designed for cutting beams, plate and bundled scrap down to charging length, so your shear handles tough sections without stalling or twisting the frame. -
Optimized Geometry for Clean, Straight Cuts:
We tune body thickness, rake angle and relief on every scrap shear knife so the edge bites quickly, holds line and leaves square, stackable pieces instead of bent or tapered ends. -
Tool Steels Matched to Real Scrap Loads:
SHJ KNIFE uses D2-type and alloy tool steels on our scrap shear blades, setting hardness and toughness to match your typical scrap mix, from light gauge stampings to heavy profiles with welds and inclusions. -
OEM-Style Fit for Hydraulic and Guillotine Shears:
We machine seating faces and holes so replacement scrap shear blades fit common hydraulic and guillotine shears with minimal adjustment, whether you supply drawings, CAD data or a worn sample.

Scrap Shear Blade | Heavy Scrap Cutting Knives
On a scrap line, the shear makes money only when the knife keeps moving. A good scrap shear blade cuts beams, plate and bundled scrap to charging length without chipping, stalling or twisting the frame. A poor blade turns into overtime, rework and broken holders.
SHJ KNIFE designs and manufactures scrap shear blades and scrap shear knives for heavy steel cutting. We match knife geometry, steel grade and hardness to your scrap mix and shear type, so you get predictable cuts and a blade life you can plan around.
Where Scrap Shear Blades Work Best ?
A dedicated scrap shear blade sits in stations that handle the heaviest sections in the yard. Typical jobs include:
- Cutting H-beams, channels, angles and tubes to furnace length
- Squaring off flame-cut plate, torch-cut parts and profiles
- Shortening bundled scrap before loading
These cuts run at lower strokes per minute than shredders or crushers but with much higher force per stroke. That is why scrap shear blades need strong bodies, solid support faces and controlled clearances with the moving knife.
Scrap Shear Blade Geometry and Fit
We start each project from your shear and the sections you cut most often. Then we define the geometry of the scrap shear blade instead of pushing a one-shape-fits-all pattern.
Key points we tune for your line:
Blade body size – thickness and width sized to your hydraulic or guillotine shear to keep the knife flat under load
Cutting edge angles – relief and rake angles that give a positive cut while still supporting the edge against heavy scrap
Seat and hole layout – accurate seating faces, bolt holes and keyways so the blade locates repeatably and shares load across the holder
Correct geometry protects both the knife and the machine. A stable scrap shear blade reduces side forces on guides and cylinders, and helps every stroke produce straight, stackable pieces.
Blade Steel Options for Scrap Shear Knives
Wrong steel either fails early or costs more than it should. For scrap shear blades we choose tool steels that balance wear and impact instead of chasing hardness alone.
Typical choices include:
- D2 / Cr12Mo1V1 scrap shear blades for standard structural scrap and plate with strong abrasion but limited shock
- Alloy tool steel scrap shear blades (such as 42CrMo-type grades) for heavier, mixed scrap where welds, inclusions and thick sections demand higher toughness
We set hardness to match your scrap and stroke force. If your line often hits thick beams or welded constructions, we keep enough toughness in the core so the scrap shear knife can take an occasional overload without catastrophic edge breakage.
For more complex cases, such as hot scrap or very abrasive material, we can discuss surface treatments or alternative steels as a separate engineering step.
OEM-Style Replacement and Custom Scrap Shear Blades
Most teams need reliable replacement scrap shear blades that drop into existing shears without long trial fitting. SHJ KNIFE supports both standard and non-standard machines:
- OEM-style blades produced to known scrap shear sizes and seat patterns
- Custom scrap shear blades made from your drawings or CAD data
- Sample-based replacements reverse-engineered from a worn blade when no drawings are available
After we confirm a final specification, we keep it on file. Future scrap shear knives follow the same geometry and steel grade, so your maintenance team can swap blades and go back to work with minimal adjustment.
Any machine or brand names you share serve only to confirm compatibility. All trademarks remain with their respective owners.
Work with SHJ KNIFE on Scrap Shear Blades
Whether you run a scrap yard, a steel mill, a service center or a foundry, you rely on the shear to keep heavy scrap moving. SHJ KNIFE supports you with scrap shear blades and scrap shear knives designed for real loading conditions, not just catalog values.
Tell us about your shear model, scrap types and current blade life. We will help you choose the right scrap shear blade design and steel so you cut safer, protect your equipment and lower cost per ton over the long term.
