The heyu vacuum quenching furnace covers both high-pressure gas quenching and oil quenching in one product family, so buyers can match the cooling medium to steel hardenability and distortion budget. The gas-quench platform reaches 6, 10, 15, 20, 40, or 60 bar with N2, Ar, or He; the oil-quench platform transfers the load in ≤12–40 seconds into an 800–14000 L quench tank. Both versions share a horizontal single-chamber layout and a modular chamber design that holds temperature and cooling uniformity tight, and they are applied to tool steel, die steel, high-speed steel, ultra-high-strength steel, bearing steel, spring steel, and alloy structural steel.
Our R&D team helps you select gas versus oil quenching based on steel grade and section size, and MOQ starts at one unit so you can trial a chamber on your own parts. The 6-to-60-bar gas platform and the ≤12-second oil-transfer platform sit in the same product family, so as your part mix shifts from thin HSS tools to thick bearing races you can choose the cooling curve that matches distortion budget without buying a second process line.

Application Fields
Tool and die steel hardening
High-pressure gas quenching minimizes distortion on complex dies compared with oil quenching.
Bearing, spring, and structural steel
Oil quenching provides the cooling rate needed for through-hardening of thick sections.
High-speed steel cutting tools
N2/He gas quenching preserves sharp cutting geometry while delivering the martensitic cooling rate HSS requires.
Customization
Gas-quench pressure grade, oil-tank volume, transfer speed, loading capacity, and heating power are configured to your part mix.
Packaging & Transportation
We support EXW and FOB terms. Equipment is packaged according to international export requirements based on the nature of the actual goods. For large equipment DDP is not available at this time; DDP can be provided for accessories and spare parts.
