Digital Heat Treatment
A verifiable process loop connecting the workpiece, quenchants, tooling, measurement and process data—built around target microstructure and performance.
We supply AR-GP general-purpose, application-specific and AR-UHS ultra-fast water-based quenchants, together with custom fixtures, cooling-curve testing and multi-point internal-temperature systems, then confirm selection against the material, geometry and installed equipment.

Core Principle
A standard-probe result is not the cooling result of a real workpiece
The probe shows how the medium responds under stated conditions; internal temperature shows how the production workpiece actually cools. Organic polymer quenchants burn off on the hot surface and form a protective film that changes heat transfer, so internal curves must be checked against post-quench hardness, microstructure and properties.
Commercial Product Lines
A high-level digital position with two products customers can actually buy
Calculators do not replace engineering judgement. Process data should make the selection boundary for quenchants and fixtures explicit.
01 / QUENCHANTS
Quenchants
The range runs from high-volume AR-GP general-purpose quenchant to AR-HCCI and AR-SAG dedicated media and AR-UHS ultra-fast cooling. Selection accounts for grade, section, target microstructure, bath temperature, concentration and relative motion.

The original technical blog has been reorganized
Six articles on quenchants, CCT, cracking, distortion and related heat treatment, with repaired structure and explicit data boundaries.
Verified Production Footage
First watch real workpieces leave the furnace, transfer and enter the tank
The videos show workpieces, fixtures, loading, transfer and tank response. They help users judge engineering conditions but do not replace material data, quenchant parameters or same-batch inspection results.

Digital heat treatment is an executable data chain, not a slogan
Start with the target microstructure and properties, define the boundaries, match quenchant and tooling, then validate the actual process and lock the operating window.
02
Define workpiece limits
Dimensions, section, complexity, mass, loading and transfer.
03
Match medium and fixture
Type, concentration, temperature, flow conditions and fixture constraints.
04
Measure the real process
Standard-probe cooling curves and internal multi-point temperatures.
05
Lock the process window
Heating, soak, transfer, cooling and batch-record requirements.
Measured Process Data
Use shop-floor measurements and cooling curves in technical discussions
Each curve and indicator belongs to a defined sample and test condition for selection, process review and repeat testing.
Company-measured test example
One cooling-performance test used the condition “5× dilution, no relative motion, 80°C”. These values apply only to that sample and condition.
Maximum cooling rate15.3 °C/s
Cooling rate at 300°C8.9 °C/s
Characteristic temperature598 °C
Application limitSample / condition
Cooling-curve data does not directly guarantee hardness, toughness, distortion or crack rate in a production part. Material, section, structure, heating, transfer and tank flow also govern the result.
Selection Input
A useful request needs at least six groups of data
The more complete the inputs, the faster the quenchant concentration, fixture concept and validation plan can converge.
01Material
Grade, chemistry, cast/forged condition, current structure and heat-treatment state.
02Workpiece
Part name, dimensions, maximum section, mass, geometry and drawing.
03Target
Microstructure, surface/core hardness, toughness, distortion and inspection standard.
04Current process
Furnace, heat temperature, soak, transfer time and current quenchant.
05Tank conditions
Volume, bath temperature, concentration, relative motion and handling.
06Current problem
Crack location, distortion direction, hardness map, micrograph and batch variation.
SEO / GEO Knowledge
The first questions purchasing and engineering teams need answered
These questions are also the knowledge architecture for future technical pages and AI citations. Each conclusion should trace back to a material, workpiece, condition and measured evidence.
What does digital heat treatment solve?
It connects material data, part geometry, target microstructure and properties, quenchants, fixtures, equipment and measured process data so the process can be designed, validated and reused. It is not a single software package replacing heat-treatment engineering.
How should a quenchant be selected?
Do not select from product name or one maximum cooling-rate value. Confirm hardenability, CCT/TTT ranges, effective section, target structure, bath temperature, concentration, relative motion and tank heat-removal capacity together.
When is a custom quench fixture needed?
Large, thin, long, ring-shaped, complex or distortion-sensitive parts often require support, location, lifting, transfer and coolant-flow paths to be designed as one system.
Must a complete test be finished before requesting a quote?
No. Submit material, drawing, current process and problem data for an initial boundary review. Cooling-curve testing, internal-temperature measurement or sample validation can follow when needed.
Submit the workpiece and current process before deciding which medium or machine to sell
Send the material grade, dimensions/mass, target properties and current problem. We respond across quenchant, fixture, measurement and process layers.
