Description

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.

Note

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.
