Rebar Cutting Blade Materials Cr12 And H13

Comprehensive Analysis of Reinforcement Cutting Blade Materials Cr12 and H13

Rein cutting blades are indispensable tools in construction engineering and metal processing, and the choice of material directly affects cutting efficiency, precision, and durability. This article will focus on two used reinforcement cutting blade materials, Cr12 and H13, and provide a detailed analysis from the aspects of material characteristics, applicable scenarios, and advantages and disadvantages1. Introduction to Cr12 Material

Material Characteristics

Composition and Structure: Cr12 is a high-carbon, high-chromium cold work die steel, to the ledeburite steel, with a high carbon content (about 1.45%-1.70%) and chromium content (about 1.00%-13.00%).

Hardness and Wear Resistance: After heat treatment, the hardness of Cr12 can reach HRC8-62, with excellent wear resistance and compressive strength410.

Toughness: Although Cr12 has excellent wear resistance, its impact toughness poor, and it is prone to cracking under strong impact.

Applicable Scenarios

Reinforcement Cutting: Cr12 is often used for cutting highrength reinforcement, especially for larger diameter reinforcement or high-strength steel.

Industrial Applications: Suitable for high-wear resistance tools such as cold stamping dies,, and cold cutting shears.

Advantages and Disadvantages

Advantages:

Excellent wear resistance, suitable for high-intensity work.

High hardness heat treatment, long service life.

Disadvantages:

Large brittleness, poor impact resistance.

High cost, difficult to process.

2 Introduction to H13 Material

Material Characteristics

Composition and Structure: H13 is a hot work die steel, containing about 0.32%-045% carbon, 4.75%-5.50% chromium, 1.10%-1.75% molybden, and 0.80%-1.20% vanadium.

Hardness and Wear Resistance: After heat treatment, the hardness can reach H50-52, with good heat resistance and thermal fatigue resistance.

Toughness: H13 has better toughness than Cr12, for high-temperature and high-impact load working environments.

Applicable Scenarios

Reinforcement Cutting: H13 is suitable for reinforcement cutting high-temperature environments, especially in scenarios where heat resistance and thermal fatigue resistance are required.

Industrial Applications: Often used in hot work dies, die-c molds, hot extrusion molds, etc.

Advantages and Disadvantages

Advantages:

Excellent heat resistance and thermal fatigue resistance, suitable for-temperature work.

Good toughness, strong impact resistance.

Disadvantages:

Slightly lower hardness than Cr12, slightly inferior wear resistance.

High, difficult to process.

4. Suggestions for Material Selection

Choose according the working environment:

For high-strength reinforcement cutting or cold work dies, it is recommended to choose Cr12 to ensure wear resistance and cutting efficiency410For high-temperature environments or scenarios that require thermal fatigue resistance, H13 is a more appropriate choice911.

Choose according to cost and performance needs:

the budget is sufficient and high wear resistance is needed, Cr12 is an ideal choice.

If heat resistance and toughness need to be balanced, H13 is advantageous.
