Steel 15KH23N18L
Designation
Description
15KH23N18L steel is used: for the manufacture of castings of parts of installations for the chemical, oil and automotive industries, gas pipelines, combustion chamber nozzle apparatus; parts, furnace fittings, requiring high mechanical strength (can be applied to the heating resistance elements).
Note
Austenitic steel, heat-resistant up to +900 °C.
At a temperature of 600−800 °C 15KH23N18L steel is prone to embrittlement due to the formation of Sigma phase.
Standards
Chemical composition
Fe is the basis.
