Product Details

ASTM A519 GRADE 1018 COLD DRAWN CARBON STEEL TUBING

 

 

AISI 1018 Steel is a Mild/Low Carbon Steel that has an excellent weldability and produces a uniform and harder case and it is a considered as the best steel for carburized parts. AISI 1018 mild/low carbon steel offers a good balance of tougness, strength and ductility.

 

With higher mechanical properties, this AISI 1018 Cold Drawn Steel also includes improved maching characteristics along with hardness, toughness and longer durability. These specific manufacturing processes are used for surface preparation, chemical composition, rollig and heating processes.

 

All thers processes develop a supreme quality product that is suited to fabrication processes such as welding, forging, machining, cold drawing and heat treating.

 

If you are interested in our prodcuts, please contact us now, for more detailed information. We assure best in class products with excellent services to our customers.

 

APPLICATIONS

  • It is used in bending, crimping and swaging processes.
  • Carburized parts that include worms, gears, pins, dowels, non-critical components of tool and die sets, tool holders, pinions, machine parts, ratchets, dowels and chain pins use AISI 1018 mild/low carbon steel.
  • It is widely used for fixtures, mounting plates and spacers.
  • It is suitably used in applications that do not need high strength of alloy steels and high carbon.
  • It provides high surface hardness and a soft core to parts that include worms, dogs, pins, liners, machinery parts, special bolts, ratchets, chain pins, oil tool slips, tie rods, anchor pins, studs etc.
  • It is used to improve drilling, machining, threading and punching processes.
  • It is used to prevent cracking in severe bends.

Heat Treatment

The heat treatment for AISI 1018 mild/low carbon steel consists of the following processes:

Normalizing
AISI 1018 mild/low carbon steel should be heated at 890°C – 940°C and then cooled in still air.
 
Forging
This process requires heating between 1150°C – 1280°C and AISI 1018 mild/low carbon steel is held until the temperature becomes constant.
900°C is the minimum temperature required for the forging process.
The steel is then cooled in air after this process.
 
Tempering
AISI 1018 mild/low carbon steel is tempered at between 150°C – 200°C for improvement of case toughness. This process has little or no effect on hardness.
The occurrence of grinding cracks is reduced when AISI 1018 mild/low carbon steel is tempered at the above mentioned temperature.
 
Annealing
The AISI 1018 mild/low carbon steel is heated at 870°C – 910°C and allowed to cool in a furnace
Stress Relieving
500°C – 700°C is required to relieve stress in AISI 1018 mild/low carbon steel that is later cooled down in still air.
 
Case Hardening
This process requires heating to be carried out between 780°C – 820°C. AISI 1018 mild/low carbon steel is then quenched in water.
 
Core Refining
This is an optional process that requires heating at 880°C – 920°C.
AISI 1018 mild/low carbon steel after being heated is moistened in oil or water.
 
Carburizing
Carburizing takes place at 880°C – 920°C.
