What Makes Our Universal Ironworker Shear Blades Stand Out?

Extended Service Life Through Optimized Heat Treatment

We adopt vacuum oil quenching paired with triple tempering to deliver consistent hardness across the entire blade cross-section, eliminating soft zones and preventing premature edge abrasion. This proprietary heat treatment extends usable service life by 30–50% versus generic market blades, reducing blade replacement frequency and production downtime.

Burr-Free Cut Quality With Precision Grinding

All seating surfaces and cutting edges undergo CNC precision grinding to achieve Ra 0.8μm surface finish and ±0.02mm dimensional accuracy. This precision ensures perfect blade alignment and consistent blade gap, producing clean, burr-free cuts that eliminate secondary deburring operations. The precisely ground 90° cutting edge maintains sharpness through thousands of cuts, delivering consistent cut quality within ±0.1mm dimensional accuracy on all sheared sections.

Chipping Resistance With Toughness Optimization

We engineer our blades for the optimal balance between wear resistance and impact toughness, a critical factor in ironworker applications where sudden shock loads occur during angle and channel shearing. Our cryogenic treatment option transforms retained austenite into stable martensite, increasing toughness by 20% while maintaining edge hardness. This reduces chipping and catastrophic blade failure, particularly when shearing heavy sections or materials with scale and surface imperfections.

Universal OEM Compatibility Guaranteed

We maintain an extensive database of OEM blade dimensions and mounting hole patterns for all major ironworker manufacturers. Every blade is CNC machined to exact OEM specifications, ensuring drop-in installation with zero machine modification. This includes blades for Geka, Peddinghaus, Scotchman, Sunrise, Kingsland, Edwards, Marvel, Harsle and all Chinese Q35Y series hydraulic ironworkers. Custom blades reverse-engineered from customer samples or drawings are available within 7-10 working days.
*Note: Please send your machine model or original blade drawing if you require custom size matching.

Four-Sided Usability for Maximum Value

Our flat bar shear blades feature four usable cutting edges. When one edge wears, operators simply rotate the blade 90 degrees to expose a fresh cutting edge. This quadruples the effective blade life before resharpening is required, delivering exceptional value for high-production shops. All edges are precision ground during manufacturing to identical tolerances, ensuring identical cut quality regardless of which edge is in use.

What Materials & Processes Ensure Ironworker Shear Blade Quality?

Premium Tool Steel Selection

We select material grades based on the specific shearing application, following the industry-standard "wear resistance vs. toughness" selection matrix. Our standard AISI D2 (DIN 1.2379, JIS SKD11) high-carbon, high-chromium cold work tool steel provides excellent wear resistance for general-purpose shearing of mild steel up to 12mm thickness. For heavy-section shearing above 12mm or applications with high shock loads, we recommend H13 hot work tool steel, which provides superior impact toughness and thermal fatigue resistance. For premium applications requiring maximum life, DC53 tool steel offers 20% higher toughness than D2 with equivalent hardness, per ASTM A681 standard specifications for tool steels. All material is sourced from certified steel mills with full material traceability and mill test reports.

Controlled Manufacturing Process

Every shear blade progresses through a strictly controlled 6-step manufacturing process with documented quality checkpoints:

1 Forging/Pre-Machining: Steel blocks are forged to refine grain structure, then rough machined to near-net shape, leaving 2mm grinding stock. QC checkpoint: Ultrasonic testing for material defects per ASTM A388.
2 Vacuum Heat Treatment: Blades undergo vacuum hardening followed by triple tempering to achieve specified hardness while relieving internal stresses. QC checkpoint: Hardness testing on every blade, with microstructural analysis per batch.
3 CNC Precision Grinding: All surfaces are ground on CNC surface grinders to achieve final dimensional tolerances and surface finish. QC checkpoint: In-process coordinate measuring machine (CMM) inspection of critical dimensions.
4 Cutting Edge Preparation: Cutting edges are honed to a precise edge radius, removing micro-grinding defects that cause premature chipping. QC checkpoint: 100% visual inspection under 10x magnification.
5 Final Inspection: Complete dimensional inspection, hardness verification, and surface finish measurement. QC checkpoint: Every blade receives a unique serial number and inspection report.
6 Preservation & Packaging: Blades receive rust-preventative coating and are individually packaged in vapor corrosion inhibitor (VCI) paper. QC checkpoint: Packaging integrity verification before shipment.

Our proprietary deep cryogenic treatment process, performed at -196°C immediately after quenching, completes the martensitic transformation and increases wear resistance by an additional 20-30% for premium-grade blades.

Where Are Our Universal Ironworker Shear Blades Used?

Frequently Asked Questions About Ironworker Shear Blades

1. Which material grade should I choose for my ironworker shear blades?

AISI D2 is the standard universal grade for general mild steel cutting up to 12mm thickness. Select H13 for heavy thick plate, hot shearing and high shock load working conditions. DC53 is recommended if you need balanced high toughness and maximum wear resistance for contaminated raw steel with scale or weld slag.

2. Are your shear blades direct OEM drop-in replacements for Geka, Scotchman and Peddinghaus machines?

Yes. Our blade database covers all mainstream global ironworker brands including Geka, Peddinghaus, Scotchman, Sunrise, Kingsland, Edwards, Marvel, Harsle and all Q35Y series Chinese hydraulic ironworkers. All mounting hole positions and overall dimensions strictly match original OEM drawings for zero-modification installation.

3. What dimensional tolerance can your CNC ground blades achieve?

Standard finished tolerance is ±0.02mm via high-precision CNC grinding, we also support customized ultra-precision grinding up to ±0.01mm for strict tolerance fabrication projects. Flatness is controlled within 0.02mm per 300mm blade length.

4. How many usable cutting edges do flat bar shear blades have?

Our flat bar shear blades feature four fully ground usable cutting edges. Once one edge dulls, simply rotate the blade 90 degrees to expose a fresh sharp edge, quadrupling service life before resharpening is needed.

5. How can I send you specifications for custom blade production?

You may provide your machine brand + tonnage model, original blade dimension drawings, physical sample photos or old blade measurements (length, width, thickness and bolt hole spacing). Our engineering team will confirm drawings within 24 working hours.

6. How long is the production lead time for standard and custom blades?

Standard universal size blades are in stock for immediate shipment. Custom reversed-engineered blades take 7–10 working days from drawing confirmation to finish production and inspection.
