can you cut cast iron with oxy acetylene
Oxy-fuel welding and cutting Oxy-acetylene can cut only low- to medium-carbon steels and wrought iron. High-carbon steels are difficult to cut because the melting point of the slag is closer to the melting point of the parent metal, so that the slag from the cutting action does not eject as sparks but rather mixes with the clean melt near the cut. This keeps the oxygen from reaching the clean metal and burning it. In the case of cast iron, graphite between the grains and the shape of the grains themselves interfere with the cutting action of the torch. Stainless steels cannot be cut either because the material does not burn readily.[14]
Cast-iron cookware Enameled cast iron is cast iron that has a vitreous enamel glaze. The enamel coating over the cast iron prevents rusting, eliminates the need to season the metal, and allows more thorough cleaning. Furthermore, pigments used in the enameling process can produce vibrant colors. While enamel-coated cast iron doesn't have the seasoning and cleaning issues of bare cast iron, it can be several times more costly, and does not have some of the benefits of bare cast iron, such as the ability to withstand searing heat and resist sticking. It limits the leaching of dietary iron, and chipping of the enamel coating can be a concern.
