Ironworker Angle Shear Blades

The Importance of High-Quality Ironworker Angle Shear Blades

In the metal fabrication industry, the ability to produce clean, fast, and accurate cuts on structural steel is a primary driver of profitability. Among the various stations of a multifunctional machine, the angle shear station is often the most used. To keep your production line moving, investing in professional-grade ironworker angle shear blades is non-negotiable.

What Are Ironworker Shear Blades?

• Core wear-resistant parts for ironworker machines (combined punching and shearing machines)

• Used for cold cutting metal profiles (angle steel, flat steel, round steel, etc.)

• Key hydraulic ironworker parts and part of ironworker tooling

• Commonly called angle iron cutter replacements when replacing

• Used in steel factories, construction sites and metal processing plants

• Material, heat treatment and precision affect cutting speed, quality and service life

Main Materials for Shear Blades

1. 9CrSi Alloy Tool Steel Blades

• Pros: Easy to process and regrind on-site, good value, moderate durability

• Best for: Light, occasional cutting; small profiles; temporary use on construction sites

• Fits: Small to medium ironworker machines (low work frequency)

2. Cr12MoV Cold Work Die Steel Blades (Most Popular)

• Hardness: HRC 58-62 (after special heat treatment)

• Pros: Great for cold cutting, durable, not easy to break/deform, 2-3x longer life than 9CrSi

• Best for: Medium/heavy, high-frequency cutting; regular industrial profiles; mass production

• Fits: 90% of medium/heavy ironworker machines

3. H13 Die Steel Blades (For Tough Conditions)

• Hardness: HRC 52-56 (after heat treatment)

• Pros: Very tough, not easy to break, works well with dirty/impure profiles

• Best for: Heavy cutting; large profiles; high-strength steel; profiles with weld scars

• Fits: Custom heavy-duty ironworker machines

Key Performance Needs

• Stable hardness (not too hard or too soft)

• Strong toughness (no breaking or deformation during cutting)

• High wear resistance (stays sharp for frequent use)

What Can They Cut?

• Angle steel: 30mm-200mm (equal/unequal)

• Flat steel: Up to 50mm thick (smooth cut, no burrs)

• Round steel: Up to 25mm diameter (no deformation)

• Channel/square steel: Custom blades for heavy industrial use

How to Make Blades Last Longer?

• Do not cut profiles larger than the blade’s capacity

• Adjust the gap between upper and lower blades (0.05-0.1×profile thickness)

• Clean profiles (remove rust, weld scars, hard slag) before cutting

• Lubricate the ironworker machine regularly

• Use professionalshear blade sharpening when blades get dull

Why Choose Our Blades?
