Proven Performance That Saves Time

Heat treatment is often the last critical step before equipment returns to service. Delays during heating or cooling extend shutdown schedules, increase labor costs, and push back project timelines. AxiomHT delivers carefully controlled heat treatment processes that reduce unnecessary downtime without sacrificing quality.
<4 Hrs
Average Cooling Time

From 800°F to 120°F using Axi-Therm™ blended heating and cooling technology, versus significantly longer conventional methods.

30%
Average Cost Savings

Lower energy consumption, fewer heating elements, and shorter equipment occupancy reduce overall project costs.

135+
Years Combined Experience

Our leadership and field experts bring decades of experience solving complex heat treatment challenges.

Patent-Pending Axi-Therm™ Technology

AxiomHT's patent-pending heating and cooling technology can improve efficiency, reduce costs, and get you back to production quicker.

Comprehensive On-Site Heat Treatment Services

Every facility has different materials, code requirements, and operational needs. Our technicians mobilize directly to your location with calibrated equipment, reducing transportation delays and keeping projects on schedule.

Preheat

Reduces thermal shock during welding by bringing the base material to spec temperature, lowering cooling rates and hydrogen-cracking risk.

Learn More

Post Weld Heat Treatment

One of the most common services for pressure vessels, process piping, and critical welds — relieving residual stress and improving ductility.

Learn More

Hydrogen Bake-Out

Applies controlled heat after welding to encourage hydrogen diffusion before it creates long-term weld defects and delayed cracking.

Learn More

Line Thaw

Controlled line thaw services that safely restore flow after freeze-ups, monitoring temperatures throughout to protect equipment.

Learn More

Thermal Stabilizing

Resolves internal stresses and stabilizes metallurgical properties so materials perform reliably under demanding operating conditions.

Learn More

Phenolic Coating Cure

Proper methods to drive heat evenly into the paint, preventing blistering, disbonding, and adhesion failures months down the line.

Learn More

Solution Annealing

Dissolves precipitates in stainless steels and specialty alloys, restoring uniform microstructure and corrosion resistance.

Learn More

Refractory Dry-Out

Carefully controlled, monitored heating schedules that let moisture escape gradually from new or repaired refractory linings.

Learn More

P91 Heat Treatment Services

P91 heat treatment has little room for error. Improper heating or cooling can produce incorrect microstructures and lead to costly rework or premature failures. AxiomHT delivers precision-controlled P91 heat treatment throughout California.

Frquently Asked Questions

On-site treatment brings equipment and technicians to the job, so parts stay in place instead of being disconnected, transported, and reinstalled. This cuts the handling time and logistics risk that shop treatment adds to a project schedule.
Typically just the area or system under treatment. Crews work within the footprint of the job site and coordinate around ongoing operations elsewhere on the property.
AxiomHT tackles jobs of all sizes ranging from single weld repairs and maintenance jobs to multi-week shutdown and turnaround work.
Yes. AxiomHT offers heat treatment services not just in California, but nationwide across the United States. We also offer rapid mobilization for urgent and shutdown projects.
Preheat happens before and during welding to reduce thermal shock and cracking risk as the weld is made. PWHT happens after welding is complete, to relieve the residual stresses introduced during welding. They address different points in the same process.
Axiom Heat Treatment combines over 135 years of field experience with patent-pending blended heating and cooling technology. Our engineered solutions can reduce cycle time by around 30% while maintaining full material integrity and code compliance
All AxiomHT projects are performed according to customer specifications and applicable industry standards such as ASME and API, as well as project-specific metallurgical requirements. We offer detailed documentation and discuss project requirements with our clients before work begins.
It's generally possible with insulated equipment and proper temperature control, though extreme weather can affect scheduling and require additional precautions to maintain consistent heating and cooling rates.
