Carbon steel is an alloy primarily composed of iron and carbon, with these two elements serving as its core components. It falls into three distinct categories: low-carbon steel, medium-carbon steel, and high-carbon steel. A variety of common materials belong to this category, including A36, A53, along with others like S235JR, S355JR, A283, A572, A192, A285, A516, A709, A533, and A333.
