Description

10Х14НДЛ steel is used: for the manufacture of castings parts, corrosion-resistant in seawater and atmospheric conditions (propellers and other parts shipbuilding).

Note

Steel corrosion-resistant in seawater and atmospheric conditions of the martensitic class. The corrosion resistance of steel higher than that of steel grades 15KH13L and 20KH13L.
