Tool & Die

Heat treating tool steel—done right, done fast

When customers in the tool & die industry need to heat treat large or specialty parts, or have a job requiring more precise process control, they turn to Paulo.

These customers have two simple demands: Get the heat treatment right and get it done quickly.

On both accounts, we deliver.

Leading equipment and expertise

Most of the tool steel heat treating we perform is carried out in vacuum furnaces in our St. Louis, Nashville and Kansas City plants. Our vacuum furnaces offer precise temperature and atmosphere controls to ensure hardened tool steel meets even the most complicated specs. They’re also versatile, able to treat parts that fit in the palm of a hand to those weighing up to 8,000 pounds.

Our vacuum furnace lines are especially appealing to customers in the high-pressure die casting industry. With a furnace in St. Louis capable of delivering a 20-bar quench and a series of furnaces in Nashville rated for 15 bars, we routinely accomplish the most technically demanding tool steel heat treatments in the industry while managing the risks inherent in the process.

We use our expertise to through harden many tool steel formulations, including A2, D2, S7, H13 and some martensitic stainless steels.

Customers are assured of quick turnaround for their tool & die components because our furnaces never stop.

In addition, we stay at the forefront of the industry by participating in panels, presenting research and sitting on die material committees through our affiliation with the North American Die Casting Association (NADCA).

Metallurgical know-how

Most of the time, our tool & die customers harbor decades of experience and institutional knowledge. But sometimes, they need a hand in specifying treatments that will result in hardened tool steel that performs as intended.

With the country’s best metallurgists on staff, Paulo sets itself apart in the industry by offering design and material selection guidance during research and development or troubleshooting. We do it because we believe customers are most successful when their outsourced heat treater acts more like an in-house department.
