About Härterei Schmidthaus
Härterei Schmidthaus GmbH is a contract manufacturer specializing in the heat treatment of metallic materials, based in Breckerfeld. The service portfolio comprises hardening, tempering, normalizing, annealing (tempering), soft annealing, stress-relief annealing, ferritization, carbide decomposition annealing and isothermal annealing (FP) – in each case with and without protective gas atmosphere. In multipurpose chamber furnaces (furnace size 1050×3500 mm) workpieces up to 5,000 kg piece weight are treated; series-produced small parts up to 20 kg are processed on roller-hearth continuous furnaces. Quenching is performed up to 1150 °C in oil, polymer or water; on two centrifugal shot-blasting machines components are subsequently blasted and descaled. Customers come from automotive, marine/shipbuilding as well as pressure equipment and plant engineering, evidenced by IATF 16949, ABS approval as well as AD 2000 W0 and EC 2014/68/EU. An in-house testing laboratory with hardness testing, metallography, tensile, impact, crack and microhardness testing issues 3.1 inspection certificates. The company, founded in 1939 in Remscheid-Lennep, is today run by the third generation of the Schmidthaus family.

Materials & Heat Treatment Processes
Heat treatment under protective gas
Hardening, tempering, normalizing and more in multipurpose chamber furnaces and a protective-gas-operated roller-hearth continuous furnace for distortion reduction.
Heat treatment without protective gas
Treatments in chamber furnaces, belt/continuous furnaces and pusher furnaces with various quenching media.
Steel (unalloyed and alloyed)
Main material for hardening, tempering and annealing processes with an optimized combination of strength and toughness.
Castings
Semi- and fully automatic testing of large castings alongside small turned parts in the in-house laboratory.
Quenching in oil, polymer or water
Various quenching media for specific requirements on microstructure and component properties up to 1150 °C.
