Description

Cast iron S-Ni35 is used: for the manufacture of casting parts with the ability to save the dimensions (e.g., machine tools); parts of scientific instruments; moulds for manufacture of glass.

Note

Nickel cast iron. Like Marche L-Ni35, has a small coefficient of thermal expansion, but more resistant to thermal shock.
