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

Preheat the steel carefully, then raise the temperature to 1150-1200°C for forging. Do not forge below 850°C.

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

 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.

  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.

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

Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each  1020 steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of alloy steel.

 1020 Carbon steel is supplied in accordance with our ISO 9001 : 2008 registration
