National Heat Treat in Houston, Texas, USA is a smaller commercial heat treater which has been in business since 2013. It offers carburizing, gas nitriding and a few other processes-as recently as 2024 the company was for sale, however it doesn’t appear to be on the market at this point in time. Just last week the company hired a new general manager, a very experienced heat treater by the name of Leo Martinez. Everybody in the commercial heat treat industry in Texas knows Leo Martinez, his career spans many years and at least two different companies. In our humble opinion this is a very good move by National.
