Description

Cast iron L-NiCuCr15−6-2 is used: for the manufacture of parts of nasosov, valves, furnaces, bushings for the ring holders of the pistons.

Note

Nickel cast iron. Has good corrosion resistance, especially in alkaline media, in dilute solutions of acids, in sea water and in salt solutions. Has good heat resistance, good bearing properties, high thermal expansion, has no magnetic properties at low content of chromium.
