Heat Treatment & Hardening Vacuum Furnace

Application Example: Comparison for Cr12MoV Steel

To help you visualize the value of vacuum furnaces, here is a specific process comparison. For the common Cr12MoV die steel, researchers compared vacuum furnace vs. traditional salt bath furnace:

• Process Results: With an appropriate vacuum heat treatment process, the distortion of Cr12MoV steel could be well controlled within the process requirements, while its hardness fully met technical standards.

• Advantage: This demonstrates that vacuum furnaces have a clear advantage in controlling distortion and ensuring hardness when processing precision, complex dies, overcoming some pain points of traditional processes.

How to Select a Vacuum Furnace

When choosing a vacuum heat treatment furnace, consider the following aspects:

• Based on product requirements: If your products demand high surface quality (bright, oxidation-free appearance) and dimensional accuracy (minimal distortion), a vacuum furnace is the ideal choice.

• Based on production volume: Select the appropriate chamber size and load capacity according to the dimensions and weight of your daily workpieces — models range from small laboratory units to large industrial furnaces capable of processing several tons at once.

• Based on process needs: For precision parts with complex shapes requiring minimal quenching distortion, prioritize furnaces with high-pressure gas quenching capability. If only annealing or tempering is needed, cooling pressure requirements are less demanding.
