What is the common casting method used for steel with low carbon content?

The common casting method used for steel with low carbon content is sand casting. This process involves using sand as the mold material, providing the ability to create complex shapes and forms with a great level of accuracy. Sand casting is particularly suitable for steel with low carbon content due to its versatility and the ability to produce components of various sizes and geometries efficiently.

Low carbon steel has excellent fluidity when molten, allowing it to fill the sand molds effectively and capture intricate details, which is essential in producing quality castings. Additionally, sand casting can handle the high temperatures required for molten steel, making it a robust choice for such applications.

Other options present different casting methods but are not specialized for low carbon steel like sand casting is, making them less suitable for this context.
