1.2601 Tool Steel |X165CrMoV12 Heat Treatment Process
1.Annealing
Process parameters:
Heating temperature: 800-850 ℃, holding time 2-4 hours, with the furnace cooling to below 500 ℃, and then air-cooled.
Hardness after annealing: ≤ 255 HBS.
2.Quenching
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
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.

1.2601 Tool Steel |X165CrMoV12 Frequently Asked Questions
Q: What is the difference between X165CrMoV12 and D2 (1.2379) tool steel?
A: X165CrMoV12 has a higher carbon (1.65% vs. 1.5%) and chromium (12% vs. 11.5%) content than D2 with optimised molybdenum and vanadium additions. This results in better wear resistance, heat treatable dimensional stability and edge retention in cutting applications. Our materials typically have 30-45% longer tool life in comparable applications.Q: Can X165CrMoV12 be machined in the hardened condition?
A: While machining with appropriate carbide tools or EDM is feasible, machining in the annealed condition (230-250 HB) is recommended for best results. Hard state machining should be limited to final finishing operations and material removal should be minimised. EDM is effective in the hardened condition if necessary.Q: What surface finishes are compatible with this material?
A: X165CrMoV12 is an ideal substrate for a variety of surface treatments, including PVD coatings (TiN, TiCN, TiAlN, CrN), CVD coatings, and nitriding processes. 12% chromium content provides good corrosion resistance that complements these surface treatments. Specific preparation protocols for each coating type can be found in the Surface Finish Compatibility Guide.Q: How does the material perform in thermal cycling applications?
A: The balanced alloy composition of X165CrMoV12 provides good resistance to thermal fatigue up to approximately 500°C. The material maintains structural integrity and hardness better than standard cold work tool steels during repeated thermal cycling and is suitable for moderate thermal stress applications. For severe thermal cycling applications, it is recommended that the technical team be consulted for special variants.
