摘要

Improvements in the obtaining of high tenacity castings, with laminar graphitization and high thermal conductivity, especially of foundries whose contents of carbon, phosphorus, chromium, hydrogen, polluting elements, sulfur and silicon are like those of the spanish patent no. 326.403, characterized because, besides providing the formation of a ferrite network as pure as possible and not distorted by acting on the sulfur content and decreasing the silicon content so that it is lower than that of a comparable normal cast iron, the manganese content is that is between 0.3% and 2.25% and, preferably, between 0.3% and 1.75%.
