What type of metal is suitable for cutting with an oxyfuel torch?

The suitable metal for cutting with an oxyfuel torch is carbon steel. Oxyfuel cutting works by using a flame to preheat the metal and an oxygen beam to create an exothermic reaction that melts and oxidizes the metal, allowing it to be blown away. Carbon steel generally has the right properties, such as a melting point that can be effectively reached by an oxyfuel torch, which allows for clean and efficient cuts.

While stainless steel can be cut with oxyfuel, it presents challenges due to its higher alloy content and properties, which may require more specialized techniques or equipment for optimal cutting quality. Aluminum can also be cut with an oxyfuel torch, but it tends to generate molten splatter and is more effectively cut with alternatives like plasma cutting. Cast iron can be problematic because its brittle nature can lead to cracking when subjected to the high temperatures of an oxyfuel flame, making it less ideal for this method of cutting. Therefore, carbon steel stands out as the most appropriate choice for oxyfuel cutting operations.
