Product Description

AISI carbon steel 1020 price, 1020 cold rolled steel

1020 steel stockholders and suppliers, delivering to the whole of the China. 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

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

Forging

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

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

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.

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

Heat Treatment

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.

Certification

1020 steel is available with a cast and analysis certificate or a BS EN 10204 3.1 mill certificate, please request when placing any orders.
