We offer our customer the biggest modern Furnace in Europa because…
we can „big and heavy“
Casehardening without limit
HARMS Lohnhärterei has since 2010 the biggest Casehardening Furnace from Europa
Case hardening for high surface hardness
Case hardening produces a hard and wear-resistent edge area and a tough core.
Case hardening consists of carburizing hardening and tempering
Steels without carbon can’t be hard During carburizing the carbon content is increased and now you get a hard surface and a tough core.
We are specialist for large case hardening Depth!
Our variable possibilities complete further gas carburizing furnaces
We realize very large carburizing depths. The furnaces operate according to the nitrogen-methanol-propane process and are controlled, regulated and monitored by a process control system. The case depth and the hardness curve are calculated by a diffusion computer module. The quenching takes place in a high-performance quenching oil with intensive forced circulation or in a polymer tank.
All heat treatment processes take place under inert gas.
