Equipment for and the components of marine vessels has to be able to endure exposure to salt fog, saltwater, and even sunlight. Corrosion resistance and strength are vital for equipment that is serving marine applications.

Heat Treating related to the Marine Industry

At Thermal Modification Technologies, we service Marine vessels with a wide range of heat-treating processes. We are well-versed in the needs and standards of equipment for marine applications as well as the best treatments for their components.

Age Hardening

Age Hardening is a popular heat treatment that enhances wear resistance, an important part of components for marine vessels. It’s often used to harden gate valves, engine parts, shafts, gears, and many other vital components.


Annealing is excellent for components that will need to be machined multiple times. Not only does this treatment improve the workability of a material, it also improves the part’s toughness and ductility. Annealing is often used for metals that will need to be worked into complex structures.

Large Capacity

We have four large-capacity furnaces and two 4,300-gallon quench tanks to process large parts for many types of Marine vessels. We can perform many different processes in these furnaces, including annealing, age hardening, normalizing, solution annealing, and stress relieving.


Normalizing removes impurities in steel components, improving their strength and hardness, more so than what can be achieved through normaling. Bars, axles, and other steel products benefit greatly from normalizing.

Post-Weld Heat Treatment

Post-weld Heat Treating can reduce dimensional changes by redistributing any residual stresses formed during welding. Heat treatment after welding can increase the toughness of the weld, especially for higher-carbon materials.

Solution Annealing

Solution Annealing is an excellent treatment for stainless steels, providing stress relief and corrosion resistance to these materials.

Stress Relieving

During machining, stresses are often introduced to a component via local deformation, and the more aggressive the feed rate into the machine, the more likely stresses will occur. Stress Relieving helps improve dimensional stability, especially in subsequent machining operations and heat treatments.
