About H+W Arnstadt
H+W Härte- und Oberflächentechnik Arnstadt GmbH & Co. KG is a contract manufacturer specialized in heat treatment, located in Arnstadt, Thuringia. The company refines and optimizes precision tools and high-quality components using heat treatment technologies, covering a broad range of processes – from standard processes to individually tailored treatments. The process portfolio includes case hardening with a defined carburizing depth or case hardening depth (CHD), tempering with tensile strength testing determined by Brinell, hardening of tool steels and high-speed steels to Rockwell or Vickers hardness levels, nitriding with a defined nitriding hardness depth (NHD), induction hardening, including partial hardening, salt bath nitrocarburizing, and short-term gas nitriding. In addition, the company offers coatings according to certificate group H-O-T, also in combination with heat treatment. Materials treated are case hardening steels, tempering steels, tool steels, high-speed steels, and nitriding steels. The offering is rounded off by a pick-up and delivery service within a 200 km radius with just-in-time delivery, so customers can forgo their own transport logistics. The quality management system is certified according to DIN EN ISO 9001:2015 and the energy management system according to DIN EN ISO 50001:2018.
