Thermal treatment
Description
Thermal processing is a sequence of operations involving heating to a specified temperature, holding at that temperature, and cooling at a designated rate for solid metals and their alloys.
If you want to improve the strength, hardness, and machinability of metal parts, then thermal treatment of steel and cast iron will be required.
The goal of thermal processing is to achieve the necessary mechanical and physical properties (such as improved machinability, increased or decreased hardness and strength of steel, etc.) of metals and their alloys through changes in internal structure and composition without altering the shape of the product.
Thermal processing can be applied either as an intermediate operation (preliminary heat treatment) to improve machinability by pressure, cutting, stress relief, and so on, or as a final operation (final heat treatment) in the technological process, ensuring the desired level of product properties.
Qualified and experienced personnel and equipment available at our company enable us to perform most known types of thermal processing.

Karbaz offers metal thermal processing services, including bluing, annealing, normalization, and hardening of various grades and sizes of steel. These processes ensure changes in material properties, making it stronger, harder, and more durable.
Bluing – This is a thermal processing method used to enhance the mechanical properties of metal. Bluing increases the metal’s strength and hardness, making it ideal for use under high-load conditions.
Annealing – This is a thermal processing method used to relieve internal stresses, improve plasticity, and increase the deformability of the material. Annealing also helps eliminate metal defects, improving its quality.
Normalization – This thermal processing method is applied to enhance the mechanical properties of metal and increase its strength. Normalization improves the metal’s structure and increases its hardness.
Hardening – This thermal processing method is used to increase the hardness and strength of metal. During hardening, the metal is rapidly cooled in special media, leading to a transformation in its structure and the formation of martensite. This makes the metal more robust and hard.
Karbaz offers high-quality thermal metal processing on modern equipment, ensuring materials with optimal mechanical properties. Our specialists have years of experience and are ready to provide our clients with top-notch services.
We provide services for hardening and normalization of steels such as 20, 40Х, 45, annealing of metals, cast iron, copper, brass, and thermal processing of metals including bushings, springs, gears, and shafts from KARBAS in Europe.
