ASTM A519 GRADE 1020 COLD FINISHED CARBON STEEL TUBING
OVERVIEW
ASTM A519 GR. 1020 Seamless Steel Tube is low hardenability low tensile Carbon Steel Tube, which is one of the most commonly used steel pipes for general purpose applications worldwide.
It offers excellent mechanical and chemical properties like high strength, ductility, weldability, and high corrosion resistance. It is normally used in turned and polished or cold drawn condition.
Due to its low carbon content, it is resistant to induction hardening or flame hardening. It will not respond to nitriding due to lack of alloying elements. However, carburization is possible in order to obtain case hardness more than Rc65 for smaller sections that reduce with an increase in section size.
AISI 1020 steel can be largely utilized in all industrial sectors in order to enhance weldability or machinability properties. It is used in a variety of applications due to its cold drew or turned and polished finish property.

Heat Treatment
Annealing
AISI 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.
Carburizing
AISI 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.
Core Refining
AISI 1020 steel is slowly cooled and re-heated at 870°C - 900°C followed by holding until the temperature remains constant all over the section and quenching in water, oil or brine.
Case Hardening
After performing the core refining process, it is re-heated to 760°C - 780°C followed by holding until the temperature is consistent all over the section. It is then quenched in water.
Tempering
AISI 1020 steel is re-heated at 150°C - 200°C followed by holding for certain time until the temperature remains constant throughout the section. It is soaked for 1 hour per 25 mm of section and then cooled under normal atmosphere. By performing the tempering process, the toughness of the case will be improved and grinding cracks will be reduced.
Normalizing
AISI 1020 steel is heated at 890°C - 940°C followed by holding until the temperature remains constant throughout the section. It is soaked for 10 - 15 minutes and then cooled in still air.
Stress Relieving
AISI 1020 steel is heated to 650°C - 700°C followed by holding until the temperature remains constant all over the section and soaking for 1 hour per 25 mm of section. It is then cooled in still air.
