Heating to 30-50 °C above Ac3, maintaining the temperature for 1-2 minutes for 1 mm of thickness. Cooling inside the furnace at a speed of 50-200 °C/hour (depending on the thickness).

Full annealing is used for pre-eutectoid steel mainly after hot forging and casting for grain refinement internal stress reduction.

Heating to a temperature of 630-700 °C (depending on the grade of steel), maintaining the temperature for 2.5 minutes for 1 mm of thickness, but not less than 1 hour. Cooling in air.

Recrystallization annealing is used to remove residual stresses and cold hardening caused by plastic deformation of metal during cold rolling, drawing or pressing.

Heating to 20-30 °C above Ac₁, maintaining the temperature for 2.5 minutes for 1 mm of thickness, cooling inside the furnace at a speed of 30-50 °C /hour to 700°C, maintaining temperature for 2.5 minutes for 1 mm of thickness, but not less than 1 hour. Cooling to 600 °C for 1 hour, then cooling in air.

Spheroidizing annealing is applied to hypereutectoid steels containing more than 0.65% carbon (for example, ШХ15 ball-bearing steels) to form a granular pearlite structure instead of lamellar.

Heating to 30-50°C above Ac3, maintaining the temperature for 1-2 minutes for 1 mm of thickness. Cooling inside the furnace at a speed of 50-100 °C/hour to a temperature of 680-700 °C, holding for 2.5-3 minutes for 1 mm of thickness, but not less than 1 hour. Cooling in air.

Isothermal annealing is a heat treatment process in which steel is treated until complete transformation of austenite into pearlite and then cooled in still air.

Isothermal annealing is the best way to obtain fine granular structure for structural and tool steels, reduce hardness and enhance steel properties to meet machinability requirements for complex alloyed steels such as18Х2НЧВА.

Heating to a temperature of 740 °C, maintaining the temperature for 2 minutes for 1 mm of the cross-section. Cooling at a speed of 50-100 °C/hour to 680 °C, maintaining temperature for 2 minutes for 1 mm of the cross-section. Repeat the cycle 2-4 times. Cooling in air.

Cyclic annealing with multiple (2-4 cycles) heating to 740 °C and cooling to 680 °C is used to achieve fine granular pearlite structure. This is mainly applicable for hypereutectoid carbon and alloyed tool and ball bearing steels.

Heating to 840 – 860 °C, maintaining the temperature for 1,5-2 minutes for 1 mm of the wall thickness, but not less than 1 hour, cooling to 600 °C inside the furnace, then in the air.

Incomplete annealing is recommended to maximize hardness reduction, improve machinability and relieve stress.

Heating to 870 – 920 ˚C for 08H18N10T and 08X17N13M2T steel types. The temperature should not be lower than 950 ˚C. Maintaining the temperature for 2 – 3 hours regardless of thickness. Cooling in air.

Stabilizing annealing is used to remove residual stresses after cold deformation and restore resistance of weld metal and the weld zone to intergranular corrosion.

Heating to 30-50 °C above Ac3, maintaining the temperature for 1-2 minutes for 1 mm of thickness. Cooling in air.

Normalization, with subsequent tempering or without it, is used to eliminate structural heterogeneity of forgings, castings, rolled metal and to refine the coarse-grained structure of the weld seam and the overheating zone in the heat affected area beside it after welding in high heat input modes (for example, electroslag welding).

It also eliminates structural heterogeneity of weld metal, improves machinability of steel and enhances its structure before quenching.

Heating up to 1030-1070 °C, maintaining the temperature for 30 minutes at a thickness of less than 10 mm, 30 minutes + 1minute for 1 mm of thickness at a thickness of more than 10 mm. Cooling in air.

Austenitization is used for welded joints from chromium-nickel steels of austenitic grade and promotes their corrosion resistance, heat resistance, ductility and resistance to local damage during operation.

Heating to a temperature of 500-710 °C (depending on the grade of steel), maintaining the temperature for 2.5 minutes for 1 mm of thickness, but not less than 1 hour. Cooling in air.

High temperature tempering is used to remove residual stresses; improve the structure and properties of the seam, as well as the heat affected zone due to the transfer of non-equilibrium quenching structures into more equilibrium ones; to remove cold work hardening resulting from plastic deformation during welding, and also to eliminate deformation aging.

High temperature tempering can be intermediate (technological) and final.

Heating to 30-50 °C below the temperature of the work hardening, maintaining the temperature for 2.5 minutes for 1 mm of thickness, but not less than 1 hour. Cooling in air.

Intermediate tempering is recommended to eliminate the danger of cracking after performing individual welding operations or cladding in cases of welding rigid joints and defect corrections with large volumes of weld metal used in certain technological processes. These parts and joints are subsequently subject to mandatory high temperature tempering.

Heating to a temperature of 180-250 °C (depending on the grade of steel), maintaining the temperature for 2.5 minutes for 1 mm of thickness, but not less than 1 hour. Cooling in air.

Low temperature tempering is carried out at temperatures of up to 250 ° C. Tempered steel retains high wear resistance, but such product (if it does not have a viscous core) will not bear high dynamic loads. Cutting and measuring tools made of carbon and low-alloy steels are typically subject to low temperature tempering.
