About Us
P & L Heat Treating, Inc. was acquired by Thermal Process Holdings, in December 2018. This acquisition is the fourth for the investment group and is part of a larger strategy of providing value added services. Our ultimate goal is to build diversified, technology-leading thermal process companies serving an attractive universe of customers, end markets, and geographies. Our culture protects the legacy and entrepreneurial spirit of our operating divisions and provides employees with long term career opportunities while continuously striving to achieve operational excellence and growth.

P&L Heat Treating and Grinding, Inc. has been located in Youngstown, Ohio for over 40 years, and  was first incorporated in 1978 by President William H. Pociask.  P & L started out in a 2500 square foot building with only two high heat austenitizing furnaces and two tempering furnaces, used for heating treating H-13 aluminum extrusion dies only. By 1982 additional building space and equipment were added, doubling the company size.

Today P & L Heat Treating operates out of a  25,000 sq foot building with 16 employees and state of the art furnaces and testing equipment, including four 12 bar vacuum furnaces, one vacuum tempering furnace, two endothermic gas high heat furnaces, nine convection tempering furnaces, and five controlled gas nitriding furnaces.

P & L Heat Treating performs a wide variety of heat treatment services. We are specialist in heat treatment of H-13, D-2, D-7, A-2, S-7, high speed steel, austenitic stainless, and alloy steels. Our controlled gas nitriding service has proven to extend the life of extrusion and forging dies by as much as three times the non-nitrided.

Our commitment to customer service and quality is always our highest priority. We are ISO9001:2015 certified and a member of MTI (Metal Treating Institute).
