Building strength for your critical parts and components

Is heat treating a necessary step in your manufacturing process? We can help. P & L Heat Treating offers the insight and expertise to assist you in procuring the right heat treating process for your projects. We understand that your parts must perform well after they have been treated and make every effort to ensure the highest quality treatment has been provided.

Take a closer look at the services we provide:


Vacuum heat treating is a process that involves removing most of the air and its reactive elements from the heat treating environment. It is often an interim or final process for a wide variety of applications. P & L Heat Treating offers vacuum heat treating services to treat parts formed from steel, exotic metals, and ferrous alloys.

Vacuum bright hardening, annealing

10-bar, high speed quench capabilities

Isothermal quenching


Hardening is a process that involves monitoring and controlling heating and cooling procedures to ensure high-quality metal and alloy products. The goal? To intensify a material’s resistance to increase strength. P & L Heat Treating supports conventional endothermic hardening services that are ideal for applications designed for strength, hardness, and durability.

Conventional endothermic with gas protection:

With fan cool

With still air cool

With oil quench

With water quench


Stress relieving is a low-temperature process used to reduce the internal material stresses within a part as a result of the manufacturing process. It does not change the material’s structure or alter its hardness. P & L Heat Treating is equipped to carry out stress relieving for all metals and plastics.

Nitrogen protection




Vacuum tempering eliminates discoloration and scaling caused by conventional air tempering. An excellent alternative for high speed and tool steels, where surface finish is critical.



Tempering is a low temperature heat treatment process. It is normally performed after a hardening process. P & L Heat Treating performs tempering to reduce the hardness in materials and increase the toughness to achieve a custom ratio for your needs.

Recirculated air



Nitriding is a heat treating process that disperses a controlled mix of ammonia and nitrogen onto the surface of a metal to create a case-hardened surface. It is an effective lower-temperature treatment that delivers superior surface qualities with a low risk of distortion. P & L Heat Treating supports state-of-the-art nitriding solutions that ensure consistency and precision.
