General characteristics

High alloy steel grade 02Х25Н22АМ2-FRI smelted in plasma furnaces with the use of special charge materials. This low carbon nitrogen-particularly stable structural steel is an efficient material used in the manufacture of critical components in equipment in the manufacture of urea. At a temperature of from -70° to +200° steel can withstand pressure up to 200 N/mm2.

The combination of high corrosion resistance and strength can be used instead of steel stamps 03Х17Н14МЗ, which increases reliability, lifetime of equipment and reduces metal consumption. It is advisable to use this steel for operation in nitrogen-, phosphorus — and sulfate media, and in return, become brand Х17Н14М2 (3)T — conditions conducive to the manifestation of pitting corrosion.


In the manufacture of welded equipment for the synthesis of acids of high concentration, in the production of mineral fertilizers, nitrophoska, extraction of phosphoric acid and other compounds, which are characterized by increased aggressiveness. Steel 02Х25Н22АМ2-PT has a high resistance against intergranular corrosion of the base metal and welded joints operated in hostile environments at temperatures up to 80 °C.

The chemical composition of the alloy:

Fe Cr C Mo Ni N Mn P Si S
DOS. From 24 to 26 ≤0,02 From 2 to 2.5 From 21 to 23 From 0.1 to 0.14 From 1.5 to 2 ≤0,020 ≤0,4 ≤0,015


Steel 02Х25Н22АМ2-FRI made in accordance with the following specifications: 14−134−277−91; 14−1-5072−91; 14−1-5203−93; 14−159−252−95.

This steel is smelted in electric arc furnaces. Classified as stainless steel corrosion-resistant ordinary heat-resistant steel. Belongs to the group of austenitic steels. This steel fully meets strict requirements of the state standard. Such iron-steel satisfactorily handled by way of cutting, expanding the possibilities of its use.

Technological processing

In forging, rolling and forging in the initial stage of the process temperature is 1170 °C, and at the end — of about 900 °C. This steel is quite easy to cut. It is welded with argon arc manual welding. In the process of manual arc welding electrodes are used with wire rod St-01Х23Н23МЗТЗ. This type of filler material is also used for automatic arc and TIG welding. To protect the welds, apply a final heat treatment.


Steel brand 02Х25Н22АМ2-PT are widely demanded in the manufacture of welded chemical equipment, for example, such as: heat exchangers, reactors, pipelines. This steel is used in the manufacture of containers which are operated in wet-process phosphoric, acetic and 55% of sulfuric acid and other aggressive environments at temperatures up to 80 °C.

This steel grade is used in equipment intended for synthesis of fertilizers, for the manufacture of welding wire and welding electrodes. It can be used as a cladding layer for tube furnace coils and two-layer corrosion-resistant hot-rolled sheets.
