Steel 55KH18G14S2TL
Designation
Description
55KH18G14S2TL steel is used: for the manufacture of castings of parts operating at high temperature and pressure (compressors and blades of the nozzle apparatus, furnace conveyors, screws, fasteners, etc.); hinged cast chains for rotary kilns, consisting of high-temperature or heat-resistant parts applied in the middle area when the temperature of the gas stream from 500−950 °C.
Note
Steel corrosion resistant, heat resistant up to +950 °C austenitic.
Steel is not resistant to exposure to sulfuric acid.
Standards
