Carbon Steel Hydraulic Fittings are generally made from high-strength carbon steel grades like ASTM A105, 20MnV6, or similar alloys. These materials provide outstanding tensile strength, fatigue resistance, wear resistance, and stability under high-pressure conditions. The fittings come with precision threads, hardened sealing surfaces, and enhanced surface coatings such as zinc plating, phosphate coating, or galvanizing for extra corrosion protection. Their mechanical properties include strong resistance to vibrations, pressure surges, and thermal fluctuations, ensuring they remain durable and leak-tight even in harsh hydraulic environments.
