When US commercial heat treater “Metlab” in PA closed their doors in 2024 it left a real void in the commercial heat treat industry when it comes to “Carburizing of Very Large Gears”. To date that void has not yet been entirely filled (although Nitrex recently added a mammoth pit nitriding furnace to one of their US locations).

Now it would appear that a commercial heat treater in Houston, Texas, “Worldwide Heat Treat” is stepping up to help fill the void. As we speak “Worldwide” is in the process of installing an atmosphere pit furnace with working dimensions of 100″ in diameter X 144″ depth. We will be adding further details as they become available.
