I will provide you with usage suggestions based on material selection, equipment matching, cutting material, and manufacturing process:


Rebar Shearing Blades Material Selection

The blade material directly determines its hardness, toughness, and service life. Choose the material according to your cutting needs:


H13  Material

Currently the mainstream high-quality blade material on the market, possessing both extremely high wear resistance and toughness, with outstanding resistance to thermal cycling. Even during long-term, high-intensity continuous cutting, it is not prone to deformation or chipping, making it suitable for large-scale processing of high-strength rebar.


Cr12MoV Material

High-hardness, high-wear-resistance tool steel. Its hardness far exceeds that of ordinary alloy blades, and it can handle the cutting needs of high-hardness cold-rolled rebar. Note that its toughness is relatively weaker; it is recommended to avoid using it in high-impact, large-gap cutting conditions.


Different types of rebar have significantly different physical properties, so blade selection needs to be based on the material characteristics:

Ordinary Round Steel: Low hardness and low cutting resistance. 9CrSi or Cr12MoV materials are sufficient, meeting basic cutting needs while controlling costs.


High-Strength Ribbed Rebar : High hardness, and the ribbed surface structure easily wears down the blade. It is recommended to use H13 material. Its excellent wear resistance and toughness can effectively reduce the risk of chipping, making it suitable for high-strength continuous cutting. 

Manufacturing Process

Blades processed through full grinding and vacuum heat treatment are preferred. These blades have a uniform hardness distribution, good edge retention, and are less prone to chipping or dulling during cutting.


Custom Rebar Shearing Blades

Our blades, through optimized hardening depth and toughness, address the common industry problem of brittle fracture when cutting high-strength rebar

High-Performance H13 Rebar Shearing Blades (AISI H13 / 1.2344 Material)

Maximize your productivity with our H13 rebar shearing blades. Engineered for the most demanding construction environments, our H13 tool steel blades provide an ideal balance of extreme surface hardness and core toughness, preventing cracks even under high-tonnage pressure.

Technical Advantages:

Premium H13 Material: Forged from high-grade H13 (AISI H13 / DIN 1.2344), known for its excellent red hardness and resistance to thermal fatigue.

Superior Impact Resistance: Vacuum heat-treated to 52-55 HRC, ensuring the blade can shear high-tensile rebar without chipping or snapping.

Universal Fit: Perfectly compatible with GQ40, GQ50, and other heavy-duty rebar shearing machines. Custom sizes are available based on your technical drawings.

Rebar shearing Machine Quick Blade Replacement: 5 Safety Steps

Core Principles: Power off and stop completely → Confirm no pressure → Standard disassembly and assembly → Precise adjustment → Test run verification.  Avoid pressurized and live electrical operation throughout the process to prevent blade pinching injuries and accidental equipment startup risks.

Step 1: Power off and lock out, completely stop the machine

Turn off the main power supply of the cutting machine, unplug the power cord/switch off the circuit breaker; manually rotate the equipment flywheel to confirm that the blade holder has no inertial movement and is completely stationary, preventing accidental equipment startup.

Step 2: Release pressure, disassemble protection

Loosen the unloading valve of the equipment's hydraulic system (for hydraulic models), completely release the hydraulic pressure inside the blade holder to prevent the blade holder from suddenly rebounding; remove the safety guard and fixing clips at the blade, and clean up rebar scraps and debris between the blade holder and the blade to ensure unobstructed disassembly and assembly space.

Step 3: Standard disassembly, gentle handling

Use a special wrench to loosen the blade fixing bolts (disassemble in a diagonal sequence to prevent deformation of the blade holder), strictly avoid directly striking the blade/bolts with a hammer; during disassembly, steadily support the blade with your hand and place the old blade properly in a non-slip, non-impact area.

Step 4: Precise installation, leveling and gap adjustment

Smoothly fit the new blade to the positioning surface of the blade holder, confirm that the blade installation direction (cutting edge facing the shearing side) is correct, and gradually tighten the fixing bolts in a diagonal sequence (even torque to prevent blade misalignment); adjust the gap between the moving and stationary blades, the conventional rebar cutting gap is controlled at 0.1~0.3mm, a gap that is too large is prone to material jamming, and a gap that is too small is prone to blade wear.

Step 5: Reset protection, no-load test run

Reset and lock the safety guard; after switching on the power, jog the equipment 2-3 times without load, check that the blade holder runs smoothly and the blade is free from jamming/abnormal noise, and after confirming that the shearing action is normal, then perform a rebar test cut. If the test cut is successful, it can be used normally.

FAQ

Question 1: What are the main material options for our rebar shearing blades?

Based on different working conditions and budget requirements, we offer three general industrial-grade alloy steel materials:

9CrSi (Alloy Tool Steel): An economical choice. It has good hardenability and machinability, suitable for cutting ordinary medium-to-low strength rebar, and is widely used in small and medium-sized projects.

Cr12MoV (Cold Work Die Steel): High-end wear-resistant type. High carbon and high chromium content, after heat treatment, it has excellent wear resistance, making it an ideal choice for continuous cutting of high-strength rebar. Its service life is much longer than 9CrSi.

H13 (Hot Work Die Steel/Red Hard Steel): High toughness and high wear resistance. It exhibits excellent resistance to chipping and thermal stability in rebar cutting applications, especially suitable for high-speed production lines or online cutting of hot-rolled rebar, and cutting of ultra-thick rebar and composite materials of scrap rebar.


Question 2: Why do my blades often chip? Is it a material problem?

Chipping is usually caused by the following factors:

Insufficient toughness: Using ultra-hard but low-toughness materials to cut large-diameter or ultra-hard rebar can easily lead to brittle fracture. In this case, we recommend switching to H13 material, as its excellent toughness can effectively absorb impact forces.

Improper clearance: Too large or too small a gap between the upper and lower blades will lead to uneven stress, resulting in chipping.

Insufficient heat treatment: Internal stress is not completely eliminated. All our blades use vacuum heat treatment technology to ensure uniform hardness from the inside out, greatly reducing the chipping rate.
