Carbon steel round bar 1020 is a lesser manufactured grade of steel than 1018 steel, and many not be as readily available as 1018. Like 1018, it can come in both hot rolled or cold drawn forms, but it is typically produced as cold drawn.
Carbon steel round bar 1020 can be welded by performing the most common welding processes. In the cold drawn or turned and polished condition, it has better weldability. It has been suggested that the welding process should not be performed in heat treated or carburized condition.
Carbon steel round bar 1020 steel is heated at 870°C – 910°C followed by holding for certain time until the temperature remains constant all over the section. It is then cooled in a furnace.
Carbon steel round bar 1020 is heated to between 880°C – 920°C in a suitable carburizing atmosphere followed by holding for sufficient amount of time to produce the needed carbon content and case depth. After this, refining/hardening and tempering processes are carried out to optimize the core and case properties.
