Steel 15KH13L (10Х13Л)
|Designation GOST Cyrillic||15Х13Л|
|Designation GOST Latin||15X13L|
|By chemical elements||15Cr13|
|Designation GOST Cyrillic||10Х13Л|
|Designation GOST Latin||10X13L|
|By chemical elements||10Cr13|
15KH13L steel is used: for the manufacture of casting parts with high ductility, subject to impact loads (turbine blades, valves, hydraulic presses, valves cracking installations, etc.); products that are exposed to relatively weak aggressive media (precipitation, wet steam, aqueous solutions of salts of organic acids at room temperature); casting parts for gas turbines and axial compressors operating at temperatures to +540 °C; casting parts, steam, gas, hydraulic turbines and compressors.
Steel corrosion resistant martensite-ferritic class.
If the steel 15KH13L used as high-temperature, the maximum operating temperature details 500 °C.
Steel corrosion resistant in atmospheric conditions, in river and tap water. Higher corrosion resistance is achieved by heat treatment and polishing.
