Heat Treat Services

Quality Heat Treating

Loenbro completes large-oven heat treating in our fabrication shop, and also utilizes proprietary 6-way and 12-way mobile heat-treatment units. Our capabilities include magnetic particle inspection, liquid penetrant inspection, positive material identification and Brinell hardness testing. Our technicians will make your part or assembly stress-free by heating to below the critical temperature and then cooling uniformly.
