Heat Treating Services

Tri-State Flame Hardening Co has been at the forefront of flame hardening and precision straightening services since 1976. Our ISO-9001:2015 certification underscores our commitment to delivering superior quality in flame hardening and vibratory stress services across various industries, including automotive, military, aerospace, medical, maritime, and consumer sectors. With over five decades of experience, we've honed our craft to provide exceptional results that meet the most demanding specifications.

At Tri-State Flame Hardening Co., we've perfected the art of tempering materials to meet your exact specifications, ensuring optimal durability and performance for your construction projects. Our specialized tempering process relieves internal stresses while maintaining the hardness your applications demand, creating building materials that stand the test of time without compromising on structural integrity.

Our annealing services carefully restore metal components to their optimal state through controlled heating and cooling processes, reducing internal stresses and enhancing workability. We've perfected our techniques over decades, ensuring your materials receive precise temperature management that meets industry standards while extending the lifespan of your critical metal components.

When materials undergo significant thermal or mechanical processes, they can develop internal stresses that compromise structural integrity and performance over time. Our specialized stress relief treatments at Tri-State Flame Hardening Co. effectively eliminate these internal tensions through carefully controlled heating and cooling cycles, restoring your materials to their optimal condition while preventing warping, cracking, and premature failure.

Our normalizing services are designed to enhance the mechanical properties of your materials, ensuring they meet the most stringent industry standards. At Tri-State Flame Hardening Co, we've perfected the process of heating materials to specific temperatures and cooling them at controlled rates to relieve internal stresses, refine grain structure, and improve machinability. This critical heat treatment process creates more uniform, stable materials that perform reliably in your most demanding construction and manufacturing applications.
