Technical characteristics

Steel 25KH13N2 (PT 474) belongs to the group chromium-Nickel stainless steels martensite-ferritic class, and intended for the manufacture of parts which are subjected to alternating loads, and operate in slightly aggressive chemical environments. Typical examples of application — production of working systems, hydraulic presses, hydropolymer devices, valves, valves nodes chemical industries. Steel is not recommended for use in welded structures, forging temperature range is 900…1230°C.

Application

Blades for steam and gas turbines, wire mesh products of high grade heat resistance, the nozzle blocks and other products, operating temperatures of operation, which does not exceed 650…700°C.

Chemical composition

C Cr Cu Mn Ni P S Si Ti
0,2…0,3 12,0…14,0 ≤0,30 0,80…1,20 1,5…2,0 0,08…0,15 0,15…0,25 ≤0,50 ≤0,020

Note. To improve subsequent machining on machine tools percentage of phosphorus and sulphur increases slightly. The heat resistance is improved in the calculation result of adding titanium to the starting material.
