Rolling Meadows, IL – 1/16/04: Bohler-Uddeholm Thermo-Tech, a world-class heat treatment facility for tool steels and specialty materials, is pleased to announce that they have been approved by General Motors as a Provisional Heat Treatment Source for Premium Grade H13 die steel and other die materials. In compliance with General Motors’s Die Insert Material and Heat Treatment Specification, DC 9999-1. Thermo-Tech has met the stringent equipment, heat treatment, processing and laboratory guidelines established by the specification.

As part of the requirements for compliance, a 16 inch cube of Premium Grade H13 certified to the DC-9999-1 material specification, was heat treated, and tested by an independent laboratory to meet a minimum impact toughness, “Charpy V” of 80% of the initial capability test results. As a result of successfully meeting the requirements, Thermo-Tech is now permitted to heat treat die cast die inserts for GM’s tool sources.

Thermo-Tech, located in Mississauga, Ontario, is a state of the art facility focused on the thermal processing of tool steel applications. In addition to the 10 bar Abar-Ipsen furnace used to qualify for this specification, Thermo-Tech operates 2 and 5 bar furnaces along with atmosphere and Vacuum Tempering furnaces, a Nu-Bit Cryogenics unit and offers the THERMONITE surface enhancement (Ferritic Nitro-carburizing) process. Thermo-Tech also operates a Metallurgical Laboratory, staffed with degreed metallurgists capable of providing certification and technical support along with tooling related application recommendations.
The company is certified to both ISO 9002, and QS-9000 standards, with TS-16949 certification pending.

Thermo-Tech is part of the overall Bohler-Uddeholm Heat Treatment Alliance in North America. The Heat Treatment Alliance allows Bohler-Uddeholm to supply the highest quality steel and assurance to customers that the best heat treatment practices are being utilized to enhance the characteristics of their products.
Thermo-Tech’s recognition as a Heat Treatment Source for General Motors further strengthens the position of the alliance, in which four of the current partners are approved, either provisionally or fully.
