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

rebar cutting blade 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.

9CrSi Material

An economical and practical choice. It has good hardenability and machinability, suitable for cutting ordinary medium- and low-strength rebar, and is widely used in small and medium-sized projects.

Matching Mechanical Specifications (Customized by Size)

Shape Matching: Common blade shapes are square (four sides usable) and rectangular. Square blades allow for the rotation of four cutting edges, significantly extending their service life, suitable for large-scale processing scenarios; rectangular blades are mostly single-sided or double-sided, suitable for small-tonnage cutting machines.

Size Matching: Different tonnage cutting machines (such as GQ40, GQ50, GQ60) have specific standards for blade thickness, length, width, and bolt hole spacing.  Selection must strictly follow the equipment's instruction manual.

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. Scrap rebar: Severely corroded surface, containing sand and dirt, causing significant wear on the blades. High-nickel materials are preferred;

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 cutting blades

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

Blade Metal Materials Grade Correspondence Table

Base Grade	Steel Category	Chinese Standard GB/T 1299	American Standard ASTM	German Standard DIN (W-Nr.)	Japanese Standard JIS
H13	Hot Work Die Steel	4Cr5MoSiV1	H13	1.2344	SKD61
Cr12MoV	Cold Work Die Steel	Cr12MoV		1.2601	SKD11
9CrSi	Alloy Tool Steel (Cutting Tool Steel)	9CrSi		1.2108

H13 blade material is really good at resisting wear and has great toughness. Even when used for long periods of high-intensity cutting, it stays stable—no deformation, no chipping at all. It’s the top pick for international trade because it doesn’t need to be replaced as often, which cuts down a lot on transportation costs and customs duties compared to other materials.
