1.2080 Tool Steel | X210Cr12| D3 Heat Treatment Process

1.Annealing

Purpose: to eliminate internal stresses generated during forging or rolling, reduce hardness, improve cutting performance, and prepare for subsequent processing and heat treatment.
Process parameters:
Heating temperature: 800-850 ℃, holding time 2-4 hours, with the furnace cooling to below 500 ℃, and then air-cooled.

2.Quenching

Purpose: to make the tool steel to obtain martensitic organization, improve hardness and wear resistance.
Process parameters:
Heating temperature: 1000-1050 ℃ (commonly used 1020-1040 ℃), holding time according to the size of the workpiece to determine, generally 30-60 minutes.
Cooling: oil cooling or air cooling (for small size or simple shape of the workpiece), large workpieces can be graded quenching (in the 260-300 ℃ salt bath cooling for a period of time and then air-cooled), in order to reduce the quenching stress, to prevent deformation and cracking.

3.Tempering

Purpose: to eliminate quenching stress, adjust the hardness and toughness, stable organization and size.
Process parameters:
low-temperature tempering: 150-250 ℃, insulation 2-3 hours, air-cooled, tempered hardness of 58-62HRC, for molds requiring high hardness and wear resistance.
Medium temperature tempering: 300-500 ℃, insulation 2-3 hours, air-cooled, tempered hardness of 50-58HRC, can improve the toughness, suitable for molds subject to impact load.
High-temperature tempering: 500 ℃ or more, insulation 2-3 hours, air-cooled, tempered hardness 45-50HRC, mainly for the need for higher toughness of the occasion.

4.Precautions

Heating process should control the rate of heating to avoid too rapid a rise in temperature leading to workpiece surface oxidation and decarburization. Protective atmosphere heating can be used or placed in the furnace charcoal and other anti-decarburization agent.

When quenching and cooling, choose the appropriate cooling medium and cooling method according to the shape and size of the workpiece to ensure the quenching effect while reducing the risk of deformation and cracking.

Tempering must be sufficient to ensure the elimination of internal stresses to avoid mold failure due to stress release during use. For large molds or workpieces with complex shapes, multiple tempering can be used.

1.2080 Tool Steel | X210Cr12| D3 Quality Inspection

1.2080/X210Cr12/D3 Tool Steel Quality Inspection

1.Surface Condition Inspection

FCS factory has a very strict quality inspection team, we will carefully check the surface condition of each piece of tool steel to ensure that the steel surface is free from cracks, folds, knots, oxidized skin, pitting, scratches and other defects.

2.Chemical Composition Testing

To verify whether the content of alloying elements meets the standard requirements and to safeguard the basis of the mechanical properties of the material. We will let the staff use full-spectrum direct reading spectrometer to analyze multiple elements at the same time. Sampling needs to remove the surface oxidation layer, using a block specimen to stimulate the test.

3.Dimension and Tolerance Inspection

FCS factory will use professional measuring tools to inspect the dimensions and tolerances of the steel to ensure compliance with the customer's contract requirements. Corresponding gauges will be selected according to the dimensional accuracy requirements, including tape measure, high-precision vernier calipers (0.02mm), micrometers (0.001mm), and special inspection gauges. Inspection items cover: diameter, thickness, width, length, hole diameter, chamfering dimensions, etc., to ensure that the tolerances and dimensions meet the contract requirements.

4.Hardness test

Our FCS factory will use professional hardness tester to test the hardness of steel to ensure that it meets the customer's contract requirements.

5.Ultrasonic Testing

Ultrasonic Testing Standard (UT Test Standard) is: Sep 1921-84 Class3 D/d,E/e.
FCS factory uses ultrasonic testing equipment to detect macro defects inside the material (such as cracks, shrinkage holes, inclusions, white spots, etc.), and every piece of round steel and plate will be examined by a second flaw detection test before shipment to ensure that the quality is qualified before shipment.

6.Microstructure Inspection

(1) Metallographic Analysis

FCS factory will use metallographic analysis instrument to detect the microstructure state after heat treatment, including carbide distribution, martensite morphology, residual austenite content, etc.

 (2) Grain size rating

FCS factory will use the comparative method to determine the austenite grain size by comparing the microstructure of the specimen with the standard rating chart, to ensure that it meets the customer's requirements.

1.2080 Tool Steel | X210Cr12| D3 Product Applications

Key Application Scenarios

High Precision Cutting Dies

D3/1.2080 steel excels in high volume drop stock and stamping operations on materials up to 3mm thick. Its excellent wear resistance extends die life by 30-40% compared to conventional steels, especially when machining abrasive materials such as silicon or stainless steel. Our customers report that over 1 million strokes can be achieved using our premium grade D3 steel with proper heat treatment before regrinding.

Industrial Shear Blades

The high carbon and chromium content of X210Cr12 steel creates the perfect balance of hardness and wear resistance for industrial shear applications. Metal fabricators using our 1.2080 steel for shear blades report 2-3 times longer service intervals compared to standard tool steel. The material's ability to maintain a sharp edge significantly improves cut quality and reduces burr formation.

Injection Molds

For injection molds that process abrasive or glass-filled compounds, our D3 tool steel offers excellent resistance to erosive wear. Excellent dimensional stability during heat treatment ensures the accuracy of critical mold components, while good polishability allows for a high-quality surface finish. Molders report consistent performance and minimal maintenance, even after hundreds of thousands of molding cycles.

Industry-specific applications

  1. Automotive manufacturing: drop and punch dies for high-volume sheet stamping; precision molding tools for transmission components; high-load bearing guides and wear plates; wire roll dies for fastener production.
  2. Aerospace industry: tools for machining titanium and superalloys; precision measuring gauges requiring dimensional stability; specialized cutting tools for composites; and wear-resistant fixtures and tool holders.

1.2080 Tool Steel | X210Cr12| D3 Frequently Asked Questions

Q: What is the maximum hardness that D3/1.2080/X210Cr12 steel can achieve?
A: Our D3 steel can be hardened to 60-62 HRC with proper heat treatment. The maximum actual hardness depends on the cross-section size, and thicker sections are usually 1-2 HRC lower than thinner sections due to hardenability limitations.

Q: How does D3 compare to D2 tool steels in cutting applications?
A: D3 (1.2080) has a higher carbon and usually higher chromium content than D2 (1.2379), resulting in excellent wear resistance but slightly lower toughness.D3 is the preferred choice for applications where abrasive wear is a primary concern, while D2 provides a better balance of wear resistance and toughness in applications where there is some impact loading.
