1055 carbon steel is a high-quality carbon steel with carbon content: 0.55%. Easy to sand. After heat treatment, it can reach HRc57-60 hardness, good toughness, but not rust resistance. Suitable for making swords. Good performance and inexpensive
This medium carbon steel is used for components of small cross section requiring low tensile strength, and heavy forgings in the normalized condition for automotive and general engineering such as axles, clutch members, shafts, pressed and punched parts, piston rods and gear racks.
