Possibility of plastic processing of spheroidal cast iron

摘要

The plastic processing possibilities for products made of spheroidal cast iron are particularly analysed. The problem of precise defining that kind of alloy in present machine industry is shown. Necessity of classification change in both, Polish and European norms for cast irons, is indicated. The main aim of research was to draw a distinction between grey cast iron with flaky graphite structure and spheroidal cast iron with nodular graphite structure in their mechanical and technological proprieties.
