Steel 15KH25TL
Designation
Description
15KH25TL steel is used: for the manufacture of castings parts that are not are exposed to permanent and variable loads (equipment for fuming nitric or phosphoric acids); many details of chemical engineering, including those working in contact with urea; furnace fittings, plates, etc.
Note
The corrosion resistant steel of the ferritic class. Steel heat-resistant at temperatures up to +1100 °C, has a satisfactory resistance to intergranular corrosion.
Standards
