The heyu vacuum gas quenching furnace is a horizontal, single-chamber, horizontal-loading unit with no special restrictions on workpiece shape, designed for minimal distortion after quenching. The modular chamber guarantees temperature and cooling uniformity, and optional single, two-stage, or multi-stage heat-exchanger cooling structures match different cooling rates. Rear-suction or front-suction quenching circulation can be paired with top-bottom or 360° all-around air-blowing modes, and vacuum water-cooled or standard Y-series air-cooled motors are available.
We build chamber layouts from your drawings, and a dedicated after-sales team supports gas composition and cooling-rate tuning after commissioning. Monthly output of 4–6 units keeps lead times predictable. Choosing 6, 10, 15, 20, 40, or 60 bar with 99.995% N2, Ar, or He lets you dial cooling rate to the steel grade, from martensitic tool steels that need a fast top-end quench to high-alloy grades that respond better to a gentler high-pressure gas stream.

Application Fields
High-speed steel cutting tools
High-pressure N2/He quenching delivers fast, uniform cooling that retains red hardness on complex tool geometry.
Die steels such as H13 and D2
6–20 bar gas quenching minimizes dimensional distortion compared with oil quenching on large dies.
Aerospace ultra-high-strength steel
Vacuum heating plus gas quenching avoids surface decarburization and oxidation on structural aircraft parts.
Customization
Gas-pressure grade (6–60 bar), gas type (N2/Ar/He), heat-exchanger stages, blowing mode, and suction position are selected for your steel grades.
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.
