Steel hardening
This heat treatment of steel is aimed at increasing the strength of the material. There are several ways.
We perform high-quality volume hardening. The essence of this technology is that when heated, not only the upper layers, but also the deep part of metal products become more wear-resistant and hard.
At the same time, two different methods are used – for carbon grades of steel and for alloyed ones. In the first case, during volume hardening, we cool the steel in water, and in the second – in oil, immersing the parts in these liquid environments to cool the metal. According to this technique, various grades of steel are heat treated on our equipment.
Cementation of metals
This heat treatment of metals and alloys is aimed at saturating their surface layers with carbon. After the metal has been enriched with carbon, it is quenched and tempered. As a result, the surface of the metal product acquires a higher endurance barrier, and the wear resistance parameter of the metal improves.
It is recommended to subject steel parts with 0.1-0.3% carbon content to cementation – then the core of such parts retains high viscosity after the hardening process.
Annealing of metals
This type of heat treatment of steels involves heating the steel products to the calculated temperatures and their further aging and slow cooling.
Four types of annealing are performed at our enterprise: diffusion, low, granular pearlite annealing and full.
This heat treatment of carbon steels solves various tasks: for example, obtaining a more uniform structure of the metal in already cast parts, elimination of internal stresses in the metal, reduction of its hardness level for further mechanical processing, reduction of the granularity resulting from previous technological operations, and so on.
Normalization of metals, steels
This type of heat treatment of steel products is close to annealing.
The main difference is that during normalization, the metal that has undergone hardening cools in the air, and during annealing – in the furnace.
The price of this service is not high, so it is in demand among our customers.
Nitriding of steel
This heat treatment of metals is aimed at saturating them with ammonia. The process consists in heating the steel or alloy to a temperature of 600-700 degrees Celsius and then keeping it in an atmosphere of saturated ammonia.
This type of heat treatment of steel gives it increased hardness and reliability, excellent resistance to corrosion in water, steam, and aggressive environments.
Nitrided metals or metal products are actively used in engineering and successfully extend the service life of spare parts and mechanisms.
