Process for producing a low alloy white cast iron and product resulting therefrom

Abstract From the Canadian patent

A process for producing a low alloy white cast iron is disclosed. The process comprises the steps of melting an alloy consisting essentially of about 2.5 to 4.0% carbon, 0.3 to 0.8% silicon, 0.3 to 0.8% manganese 0.75 to 2.0% nickel and O to 0.75% chromium the balance, being iron except for incidental impurities commonly found in cast irons; casting such alloy into moulds to produce the desired product; removing the product from the moulds while its surface temperature is above the transformation temperature of the alloy; and cooling it by quenching into a liquid medium containing water and an organic polymer at a sufficiently high rate to prevent the formation of pearlite but not so high …
