VACUUM HARDENING
The purpose of hardening is to achieve a hard martensitic structure or, in some cases, a bainitic structure. It includes austenitization, rapid cooling, and tempering.
This type of heat treatment of steel and other iron alloys allows for the production of components with increased hardness. The treatment is carried out at various temperatures, depending on the type of steel. The process involves heating the steel components, holding them at a specific temperature, and then cooling them.
Vacuum hardening of steel
Vacuum hardening is an essential service for achieving a material with a clean surface, high shape repeatability, and minimal distortion.
Depending on the type of material, shape, and cross-section of the parts, as well as operational requirements, we perform bulk vacuum hardening with cooling in oil or gases under high pressure. This ensures reduced distortion and, consequently, allows for smaller grinding allowances.
We have modern vacuum furnaces, in which the cooling:
Is carried out using next-generation vacuum oil based on GTL, which is particularly effective for larger components made of low-hardenability steel
Using nitrogen expanded from its cryogenic form, of the highest purity, at a maximum pressure of 8, 13, or 15 bar
The result is a product with high repeatability while optimizing production costs. Vacuum hardening services for steel are highly effective in the manufacturing industry, particularly in the fields of machinery and automotive technology.
max. dimensions of the working chamber for bulk vacuum hardening:
We offer hardening processes in vacuum furnaces with a maximum load capacity of 1200 kg gross. The dimensions of the working chambers are as follows:
a = max 1200mm
b = max 900mm
c = max 750mm
The dimensions apply to processes such as hardening and carburizing (cooling in oil or gas), aging, solution heat treatment, tempering, annealing, and brazing in a vacuum chamber furnace.
