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.
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.
Wear resistance: Cr12MoV has significantly better wear resistance than 9CrSi. Under the same working conditions, the number of cuts for Cr12MoV is usually 2-3 times that of 9CrSi.
Cost: 9CrSi is more cost-effective, suitable for projects sensitive to initial purchase costs; although the unit price of Cr12MoV is slightly higher, its lower replacement frequency results in a lower overall cutting cost per ton of rebar.
For high-strength or ribbed rebar, we strongly recommend H13:
If you are facing extremely high operating intensity and are concerned about downtime due to blade chipping, choose H13. Its impact fatigue resistance is top-notch in the rebar processing industry.
Yes. We understand that blade specifications vary among different equipment brands (e.g., from Italy, Germany, or China). We are equipped with a full set of CNC machining equipment, and you only need to provide the following information:
Detailed drawings (including length, width, thickness, and hole dimensions).
Material requirements (9CrSi, Cr12MoV, or H13).
Specifications of the workpiece to be processed (rebar diameter and strength grade).
We can provide a 1:1 precise customized solution.
Regular rotation: Our blades are usually designed with 4 or 8 cutting edges. Please rotate the blade promptly when one cutting edge becomes dull.
Tighten bolts: Ensure the blades are securely installed. Any slight looseness will cause destructive impact during the cutting process.
Control the gap: Adjust a reasonable blade gap according to the rebar diameter, usually about 10% of the rebar diameter.
