Description
Alloy V56 is used: for the manufacture of casting in metal chill castings in the form of bars and maslot intended for the production of parts of friction, operating at ambient temperatures of 400−450° C, the rarefied atmosphere of 15−20 mm Hg. article, high loads and sliding velocities.
Note
Alloy wear-resistant and heat-resistant Nickel-based.
