AISI 1020 Mild Carbon Low Tensile Steel Bar Forging 130-1600mm

 

 

INTRODUCTION

 

AISI 1020 is a low hardenability and low tensile carbon steel with Brinell hardness of 119 – 235 and tensile strength of 410-790 MPa. It has high machinability, high strength, high ductility and good weldability. 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. Due to lack of alloying elements, it will not respond to nitriding. However, carburization is possible in order to obtain case hardness more than Rc65 for smaller sections that reduces with an increase in section size. Core strength will remain as it has been supplied for all the sections. Alternatively, carbon nitriding can be performed, offering certain benefits over standard carburizing.

 

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 drawn or turned and polished finish property.

 

 

Applications of 1020 Mild Steel

 

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

Comparative Materials

  • AISI 1018 Steel: This type of steel shares much of its properties with 1020 steel such as ease of machining, weldability and strength. It is the most common cold rolled steel available in the market
  • AISI 1006 Mild Steel: This type of mild steels which have low hardness and are used in drawing. They are also very machinable and can be welded easily although its hardness is much lower than AISI 1020

Fabrication and Heat Treatment

 

Machining

In the cold drawn or turned and polished condition, AISI 1020 steel has high machinability. As per recommendations of machine manufacturers, AISI 1020 steel can be used for drilling, turning, milling and tapping operations using suitable feeds, tool type and speeds.

 

Weldability
AISI 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.

 

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.
