What is Grade 1020?
Grade 1020 is a low carbon steel (0.18-0.23% C) with excellent weldability and formability. This 1020 tube is a general purpose grade suitable for non-critical mechanical applications requiring good machinability and moderate strength. The aisi 1020 tube offers better strength than 1018 while maintaining good forming characteristics. It can be case hardened for improved surface wear resistance when required.
