Core advantages
Multi-stage gas and liquid quench sequences lock in fine-grained microstructures across every batch of chrome-moly steel.
Reduces operator guesswork and scrap rate.Composite crucibles withstand repeated 2000°C cycles and rapid thermal shock without cracking, keeping melt chemistry clean.
Lasts 3x longer than standard ceramic pots.Induction heating under vacuum prevents oxidation and decarburization, preserving alloy composition during sintering.
Oxygen levels below 10⁻⁵ mbar.Programmable profiles log real-time cooling curves, enabling traceable quality assurance for each heat treatment run.
Export data directly to your LIMS.Consistent heating and quenching parameters produce uniform austenite-to-martensite transformation across the entire billet.
Meets ASTM E112 grain size specs.Terms and conditions that remove ambiguous interpretations regarding our vacuum induction furnaces, refractory crucibles, and quenching processes for chrome-moly steel alloys.
The HVF-2000 vacuum induction furnace is rated for continuous operation up to 2000°C. This temperature is measured at the crucible hot zone under vacuum conditions. Ambient pressure and gas backfill can reduce effective temperature by up to 50°C. All published specifications assume a base pressure below 10⁻² mbar.
Our refractory crucible set is chemically inert for chrome-moly alloys with chromium content up to 12% and molybdenum up to 1.5%. For higher alloy content, a zirconia-based liner is recommended. The crucible lid and pouring lip are included in the set; separate purchase is not required.
Grain refinement is measured by ASTM E112 average grain size number. Our QuenchPro Control Module achieves a minimum of two full grain size number improvement compared to uncontrolled cooling. This is verified by metallographic cross-section analysis performed on a test coupon from the same batch.
Yes. The module controls up to three independent quench circuits: one for inert gas (argon or nitrogen) and two for liquid media (water or polymer quenchants). Each circuit has its own flow control valve and temperature sensor. The user selects the media per stage in the programmable profile.
The alumina-graphite crucible set is warranted against manufacturing defects for 12 months from the date of shipment. Thermal shock cracking due to improper preheating or exceeding the recommended heating rate of 15°C/min is not covered. A usage log is required for any warranty claim.
Retrofitting is possible for furnaces manufactured after 2018 that have the auxiliary control port. Older units require a control panel upgrade at additional cost. The retrofit kit includes the module, wiring harness, and mounting bracket. Installation takes approximately 4 hours on site.
The HVF-2000 vacuum induction furnace operates from ambient up to 2000°C, with precise control within ±5°C. This range covers sintering, heat treatment, and solution annealing for chrome-moly steel alloys. The system maintains vacuum integrity throughout the cycle, preventing oxidation and ensuring repeatable results across batches.
QuenchPro automates multi-stage cooling profiles using gas or liquid media. By controlling the quench rate at each phase, it suppresses undesirable phase transformations and promotes uniform grain refinement. Operators can store up to 50 programs, reducing variability and improving mechanical properties like hardness and toughness in chrome-moly steels.
Yes, our alumina-graphite composite crucibles are specifically formulated for reactive alloys like chrome-moly. The material offers high thermal shock resistance and chemical inertness, minimizing contamination during melting. Each crucible set includes a lid and pouring lip, and is available in sizes from 1 kg to 50 kg capacity to match your batch requirements.
Cycle time depends on alloy composition, target microstructure, and furnace load. For a standard chrome-moly steel batch, the full sintering and quench cycle ranges from 4 to 8 hours. The QuenchPro module can reduce cycle time by optimizing cooling rates, and real-time data logging helps validate each run for quality assurance.
