After chemically separating several samples of cast iron material, and analyzing and evaluating the test data, we decided to have our own specification of cast iron made exclusively for us. We specify elements such as carbon, silicon, manganese, nickel, chromium, copper and sulfur to produce a highly pearlitic structure with dense fine grains, and excellent wear resistance.
