Tempering of drop forgings

 

✔ Most modern continuous tempering and all annealing processes possible

✔ Complete QA management with certification to DIN ISO 9001 and laboratory accreditation to ISO 17025

✔ Extensive laboratory equipment and sample production line for determination of mechanical parameters

The HARMS Vergüterei GmbH & Co. KG started operations in summer 2003. The decision to set up a modern tempering line was long overdue due to our many years of successful cooperation with renowned stainless steel forges. The construction of the tempering shop, as a completely new segment within the Harms company, was adapted to the high requirements of drop forgings especially for the automotive industry and equipped with the latest control and process monitoring technology.

Tempering is understood to mean hardening with subsequent tempering to temperatures of approx. 550 to 650 ̊ C. The microstructural changes occurring in the material result in a significant increase in toughness in addition to high strength.

A main focus during the design of the entire plant was the provision of state-of-the-art sample production and testing technology. With the recent laboratory accreditation according to ISO 17025 and the self-evident DIN ISO 9001 certification, we are thus able to completely treat and certify the most demanding components.
