Description
08kh18tch steel is used: for the manufacture of household items, equipment, food and light industry and other products used at the operating temperature to -20 °C; electropolishing pipes.
Note
Steel corrosion resistant ferritic grade, micro-alloyed rare earth element cerium.
Steel 08kh18tch recommended as a substitute for steel 12KH18N10T, and also has a few more enhanced plasticity and polishing properties in comparison with steel 08KH18T1, replaces steel 08KH18N10T in environments where General corrosion in the food industry.
