VACUUM HARDENING
This type of heat treatment of steel and other iron alloys allows you to obtain elements with increased hardness.
Such processing is carried out at various temperatures, depending on the type of steel. The process involves heating steel components, maintaining them at a specific temperature, and then cooling them. 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.
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, cross-section of the parts, and operational requirements, we perform vacuum hardening using bulk processes, 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 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 maximum pressures 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 manufacturing industries, 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.
