Product Overview
ALAS heavy-duty ironworker flat bar shear blades are high-wear-resistant cutting parts exclusively designed for industrial hydraulic ironworkers. As essential replacement parts and flat bar cutting dies for metal fabrication workshops, the blades cut carbon steel, alloy steel and stainless steel flat bars under cold working conditions. They output stable hydraulic shearing force, while eliminating cutting-edge burrs and workpiece deformation. Manufactured from premium DC53 cold-work steel and H13 hot-work steel, these industrial-grade flat bar cutter consumables deliver consistent performance across all major ironworker brands. With more than 15 years of industrial tooling manufacturing experience, ALAS delivers fully compatible and customizable shear blades, supported by strict in-house quality inspection and traceable production records. We complete all manufacturing procedures inside our Nanjing Jiangning factory, supplying impact-resistant, crack-proof blades at pure factory price, with no intermediate markup.

Materials & Processes That Ensure Quality
Raw Material Selection: We use certified H13 and DC53 tool steel complying with ASTM A681. H13 excels in high impact toughness and shock resistance, preventing edge chipping, while DC53 offers superior hardness and wear resistance for lasting cold shearing performance. Every batch comes with official mill test certificates and full traceability. Our premium H13 tool steel features exceptional red-hardness and thermal fatigue resistance, maintaining its structural integrity even during high-friction, continuous shearing operations.
Full-Link Manufacturing Process: Five closed-loop procedures with embedded QC checkpoints — Constant-temperature die forging (1120 °C) → Gantry rough milling → Customized vacuum heat treatment (segmented quenching + gradient tempering) → 5-axis precision grinding → Finished-product deburring and anti-rust oil spraying.
① Die Forging 1120 °C constant-temperature, eliminates internal cavity defects
② Rough Milling Removes oxide layers, controls blank tolerance within ±0.02 mm
③ Vacuum Heat Treatment Segmented quenching + gradient tempering to avoid cracking
④ Precision Grinding 5-axis grinding for cutting edges and mounting surfaces, real-time sampling
⑤ Anti-Rust Packaging Sprayed with anti-rust oil, adapted for long-distance sea shipping
Hardness control: H13 blades are finalized at HRC 50–55 to balance toughness and rigidity, preventing hydraulic impact cracking; DC53 blades are optimized at HRC 58–62 to maintain long-term cutting sharpness for continuous production runs.
