Salt Baths

Salt baths increase metallurgist’s level of flexibility in how they conduct the process of heat treating steel. With other quenching media, metals of varying shape or hardness can display a tendency to warp or twist during the process. This can result in cracked parts or parts otherwise unable to perform their intended function. But thanks to salt baths, parts can be suspended during quenching, reducing the chance for part distortion that exists with other methods.

Because the problem of distortion is one that typically occurs for longer parts, Paulo’s salt baths are made to accommodate parts measuring up to 54 inches long. Another benefit of salt baths is the wide range of available operating temperatures, which adds a degree of flexibility. Lower temperatures (around 350 degrees Fahrenheit, depending on the material) can be used when there are special concerns for cracking or distortion control in a process known as marquenching. Higher temperatures (around 600 degrees Fahrenheit, again depending on the material), on the other hand, can be used to achieve an extremely strong yet ductile final product in a process known as austempering.

And because you can rely on our Production Information and Customer Service system (PICS), you know you can count on precise, computer-controlled operating temperatures to yield consistent results. When treating with Paulo’s salt baths, our customers can expect their parts to be free from cracking and distortion to be limited. Every time. PICS helps us deliver.
