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.
If you are interested in our products, please contact us now for more detailed information. We assure best in class products with excellent services to our customers.
APPLICATIONS
AISI 1020 steel is used in case hardened condition. The applications of AISI 1020 steel are:
-It is used for simple structural application such as cold headed
bolts.
-AISI 1020 steel also finds use in the following components:
- axles
- general engineering parts and components
- machinery parts
- shafts
- camshafts
- gudgon pins
- ratchets
- light duty gears
- worm gears and
- spindles

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.
