And whether 1020 cold rolled steel is coated, galvanized, or polished. There are 4,532 1020 cold rolled steel suppliers, mainly located in Asia. The top supplying countries are China (Mainland), Saudi Arabia, and United Arab Emirates, which supply 99%, 1%, and 1% of 1020 cold rolled steel respectively.
Rolling is classified according to the temperature of the metal rolled. 1020 Cold Rolled Steel is a plain carbon steel and has a nominal carbon content of 0.20% with approximately 0.50% manganese. Because of its chemical makeup 1020 Cold Rolled Steel has a good mixture of ductility and strength. It may be carburized or hardened.
1020 steel responds well to cold work and heat treating. Weldability is fair. Applications: Shafts, lightly stressed gears, hard wearing surfaces, pins, chains and case hardened parts where core strength is not critical. 1020 is suitable for case hardened parts where core strength is not critical. Key Words:
Grade Summary: C1018 is a general purpose low carbon steel with good case hardening qualities. It has a higher manganese content than certain other low carbon grades, such as 1020. Cold Rolled C1018 is better steel for carburized parts, since it produces a harder and more uniform case.

AISI 1020 steel is also known as C1020 steel in cold worked (cold rolled and cold drawn) condition. 1020 carbon steel is one of the most commonly used plain carbon steels, has good machinability and weldability. SAE AISI 1020 mild steel can be hot rolled or cold drawn, but it is usually in turned and polished or cold drawn conditions.
