Carbon Steel Flanges are mainly made up of iron and carbon, along with trace amounts of manganese, silicon, and other elements that boost their strength and toughness. The carbon content, which typically falls between 0.2% and 0.6%, plays a crucial role in defining their mechanical properties, such as tensile strength, hardness, and impact resistance. These flanges are crafted through precise forging or machining processes, ensuring uniformity and durability. They can also be heat-treated to enhance their mechanical performance, allowing them to endure high pressure, temperature, and stress in demanding industrial settings.
