|Designation GOST Cyrillic||03Х17Н14М2|
|Designation GOST Latin||03X17H14M2|
|By chemical elements||03Cr17Н14Mo2|
03Х17Н14М2 steel is used: for the manufacture of welded parts of enhanced chemical durability in the pulp and paper, chemical and textile industry; equipment for the production of wool and artificial silk; equipment operating in contact with sea water; equipment for display of films; boiler drums; capacitive equipment for waste oil and for coking plant.
The analog of AISI 316 steel, X2CrNiMo17−12−2, 1.4404, 316 L, SUS 316 L.
Steel austenitic netacademy. Technological 03Х17Н14М2 properties of steel at high temperatures much better than comparable steels that do not contain molybdenum.
|Steel pipes and fittings to them||В62||TU 14-158-135-2003|
According to TU 14-158-135-2003, the chemical composition of steel grade 03Х17Н14М2 is determined in accordance with GOST 5632-72. In view of the lack of this brand in GOST 5632-72, the chemical composition is given in accordance with the steel grade 03Х17Н14М3 with a decrease in the mass fraction of molybdenum in accordance with the marking (by approximately 1%).

Description mechanical marks
|σU||Limit short-term strength|
|d5||Elongation after rupture|
|Corrosion resistance||The presence of molybdenum (Mo) in the steel makes it particularly resistant to corrosion. Steel has a high resistance to the ICC and applied at temperatures up to +450 °C.|
